The ghost crab is perhaps one of the most interesting and unusual creatures on the beach. These crabs are easily identified by their pale coloring and translucent shell, which makes them almost invisible against the sand. What makes these crabs really interesting, however, is their behavior. Ghost crabs are known for being very playful and active, and they are always exploring their surroundings. They are also quite fearless, and will approach people if they feel like it. If you’re lucky enough to see a ghost crab on the beach, make sure to take a close look at its unique personality!

Ghost Crab

Ghost Crab Description

Ghost crabs are a type of crab that is found on beaches around the world. They get their name from their ability to blend in with the sand , making them very hard to see. Ghost crabs are nocturnal creatures and spend most of their time in burrows that they dig in the sand. These burrows can be up to 3 feet deep and 6 feet wide . During the day, ghost crabs will close the entrance to their burrow with sand to stay cool and avoid predators. Ghost crabs are opportunistic eaters and will eat just about anything they can find, including insects , small animals, and even other crabs. Ghost crabs are also known for their ability to run very fast. Ghost crabs are interesting creatures that are fun to watch and learn about.

Ghost Crab Habitat

Ghost crabs are a type of crab that lives in the sand on beaches . They get their name from their ability to blend in with the sand and from their nocturnal habits. Ghost crabs are not very social and live alone in burrows that they dig themselves. The Ghost Crab’s diet consists mostly of small invertebrates that live on the beach, such as bugs and worms. Ghost crabs also like to eat vegetables and sometimes other crabs. Ghost crabs are important to the ecosystem because they help to keep the beach clean by eating dead animals and plants. Ghost crabs are also an important food source for other animals, such as birds . Ghost crabs are threatened by habitat loss due to coastal development, pollution, and climate change.

Ghost Crab Diet

Ghost crabs are opportunistic feeders and will consume a variety of food items. The diet of ghost crabs is primarily determined by what is available in their local environment. Ghost crabs have been known to eat small mammals , reptiles , birds , carrion , and even other Ghost crabs . Ghost crabs will also scavenge for food items such as seaweed , clams , and dead fish . In addition to their scavenging activities, Ghost crabs are also able to capture live prey . Live prey items that have been identified in the diet of Ghost crabs include small insects, snails, and crabs. Overall, the Ghost crab diet is quite variable and dependent on what is available in their local environment.

Ghost Crab Size

Ghost crabs are small crabs that range in size from about 2 to 3 inches long . They are named for their pale, translucent shell , which makes them look like ghosts. Ghost crabs are found on beaches around the world, where they burrow into the sand to make their home. They are scavengers and will eat just about anything they can find, including dead fish, seaweed, and even other ghost crabs. Ghost crabs are also known for their agility and speed. They can run up to 9 miles per hour, making them one of the fastest animals on the beach. When they feel threatened, they will sometimes play dead to avoid being eaten by predators. Ghost crabs are fascinating creatures that play an important role on the beach ecosystem.

Ghost Crab Lifespan

Ghost crabs are one of the most interesting creatures on the beach. These nocturnal animals are well known for their unique appearance, as well as their fleet feet. Ghost crabs are also relatively short-lived creatures , with most individuals only living for 2-3 years . Despite their relatively short lifespan, ghost crabs play an important role in the ecosystem of the beach. Ghost crabs are opportunistic eaters, and their diet helps to keep the population of other animals in check. In addition, ghost crabs help to Aerate the sand and keep the beach clean. As a result, Ghost crabs play an important role in the health of the beach ecosystem despite their short lifespan.

Ghost Crab Behavior

Ghost Crabs are unique creatures, known for their nocturnal habits and their ability to burrow quickly into the sand. These crustaceans are also highly adaptable , able to live in a variety of habitats ranging from the intertidal zone to the open ocean. Ghost Crabs are opportunistic feeders, and will scavenge for food as well as hunt live prey. They are also known to be aggressive , and will defend their territory from other Ghost Crabs. Ghost Crab behavior is therefore complex and fascinating, making them a popular subject of study for scientists.

Ghost Crab Speed

Ghost crabs are among the fastest animals on the planet, reaching speeds of up to 25 miles per hour . They are able to achieve these high speeds thanks to their long legs and large claws, which they use to propel themselves forward. Ghost crabs are also incredibly agile, able to change direction quickly and easily. This makes them difficult to catch, even for the swiftest predators. Ghost crabs are native to tropical and subtropical regions, where they live on beaches and in sand dunes. They are nocturnal creatures, spending the day buried in the sand and emerging at night to hunt for food. Ghost crabs are omnivorous, eating everything from other crustaceans to plants and small mammals. These fascinating creatures are a joy to watch, whether they’re scurrying along the beach or playing hide-and-seek in the sand dunes.

Ghost Crab Hunting

Ghost crabs are a type of crab that is found in tropical and subtropical climates. They get their name from their ability to change their color to match their surroundings, making them difficult to spot. Ghost crabs are excellent scavengers and can often be found near the shoreline, searching for food. Ghost crab hunting is a popular activity in many coastal areas , as they are considered to be a delicacy. The best time to hunt for ghost crabs is at night, when they are most active. Ghost crabs can be caught using baited traps or by netting them as they scurry along the beach. Once caught, they can be cooked and eaten whole. Ghost crab hunting is a fun and challenging way to enjoy the outdoors and learn about these fascinating creatures.

Ghost crabs can be great pets. They are fun to watch as they dart around and dig their burrows in the sand. To care for ghost crabs you will need a large tank with plenty of deep sand for them to dig in. You will need to provide a varied diet, constant access to saltwater, and make sure they have a stimulating environment.

Providing a Good Environment

Step 1 Get a large tank.

  • A glass aquarium is the best option for your container, but you can use a cheaper plastic container if necessary.
  • Make sure that the container you use is strong enough to hold wet sand, which can get heavy. [2] X Research source
  • It should also have a lid that fits tightly to stop the crabs from getting out. It should let in air while keeping in the moisture. [3] X Research source

Step 2 Add some sand.

  • You can buy “crab sand” at your local pet store, but it will generally be quite expensive.
  • A cheaper option is to buy clean play sand from a hardware store. As long as the sand has not been contaminated it should be fine for your crab. Check for any tears in the bag, discolouration, smells or leaks before you buy.
  • You can also use coconut fibre substrate, or use a combination of this with some clean play sand. [5] X Research source

Step 3 Provide a varied environment.

  • Provide a sloped area of sand to help with burrowing.
  • Avoid putting in any resinous (evergreen) wood into the tank. Cedar and pine can irritate crabs. [7] X Research source

Step 4 Keep it humid.

  • A humid environment will help them keep their gills moist and help them breathe. [8] X Research source
  • Dehydration can have a serious effect on the health and vitality of your crabs.

Caring For Your Crabs

Step 1 Provide your crabs with water.

  • You should ensure you have a dish of saltwater in the tank that you change at least every two weeks.
  • Create saltwater by mixing two and a half teaspoons of sea or aquarium salt with a gallon of water to reach a gravity reading of around 1.01-1.08.
  • Be sure you leave the water to sit overnight so that the chlorine and chloramines dissipate before you place it in the tank.
  • Make sure the dish is easy for your crabs to get in and out of.
  • You crab can also get moisture from wet sand. [10] X Research source

Step 2 Feed your crabs.

  • Provide a variety of vegetables, fruit, fish and meat to your crabs and see which foods they like.
  • Crabs really enjoy a variety of food, so try different natural foods and have not been treated with any pesticides or chemicals. [12] X Research source
  • Avoid too much repetition in your crab’s diet and pay attention to what food he likes the most. [13] X Research source
  • You can also buy prepared crab food from your pet store as a reliable and easy option.

Step 3 Clean the tank.

  • Sift the sand more often the more crabs you have.
  • With one crab, every three weeks is fine. With four, every week. With six or more, it's good to sift every other day. [15] X Research source

Step 4 Reshape the environment.

About This Article

Pippa Elliott, MRCVS

To care for ghost crabs, fill a glass aquarium tank that's at least 20 gallons in size with enough sand for your crabs to burrow and dig in. You should also provide your crabs with places to hide and things to climb on, which you can do by adding a few clean shells, plastic plants, or bits of driftwood to their tank. Since dehydration can have a serious effect on a crab's health, make sure to always provide your crabs with a dish of salt water and keep their tank at 70% humidity, which will help them breathe and keep their gills moist. During feeding time, offer your ghost crabs a variety of foods, like vegetables, fruit, fish, and meat, to see which they prefer.

Things You Didn’t Know About Ghost Crabs

what does a ghost crab eat

Maybe you’ve lived on the coast your whole life, or perhaps you just visit a few times a year. Either way, you’ve probably seen little white crabs scooting across the sand at night.

The Ocypode Quadrata,  also known as the Ghost Crab, is found in tropical and subtropical climates around the world. No stranger to Florida’s Gulf Coast, the creature is nocturnal, although they sometimes make daytime appearances as well.

Ghost Crabs are generally pale in color, but they have the ability to change color to blend in with their surroundings.

Ghost Crabs have a square body that can grow up to three inches in size. They have four pairs of legs, one pair of claws and stalked eyes that can swivel 360 degrees. Ghost Crabs make a unique bubbling sound by hitting their claws on the ground and rubbing their legs together. Their scientific name, Ocypode means “fast feet,” as they’re often seen darting sideways at up to 10 miles per hour.

While the Ghost Crab breathes oxygen, they must also maintain plenty of moisture in their gills. They do this by acquiring water at the edge of the gulf or by getting moisture from damp sand. Ghost Crabs feed on sea turtle hatchlings, turtle eggs, clams, insects, and other crabs.

Ghost Crabs live in tiny burrows in the sand, preferring a solitary life with only one crab per burrow.

Dug at a 45-degree angle, these burrows may be up to four feet deep. They create the angled entrances so that the onshore breeze can blow into them for ventilation. The habitats can also easily be closed off during the heat of the day to keep the crabs cool.

Of course, while it’s part of many childhood rituals to chase Sand Crabs at night (rarely actually catching them, of course), please use the opportunity to teach children about these special creatures, and to always respect and value life.

Please also remember to always use turtle-safe flashlights when on the beach at night! Our local sea turtles need your help.

Ghost Crab (Sand Crab)

What is a ghost crab.

Table of Contents

Scientific Classification

Table of content.

This animal is also known as “Sand Crab” or “White Crab”. These are also known as “Mole Crabs”.

Description

This animal has a pale body color that is similar to the color of sand. This makes it nearly invisible when it crawls about over sand. It is because of this apparent invisibility that the crab has got its unique name. The name is also suggestive of the fact that the activities of this creature are mainly restricted to night.

This animal has five pairs of legs. The first pair is called Chelipeds and is shaped like claws. The legs, when jointly used, can make crabs move in any direction – forward, backward or sideways. In male crabs of this species, one claw is slightly larger than the other.

It has large black eyes that are supported on stalks. Its eyes help it see in any direction. There are horns attached to the end of the eyes of male crabs. It is by these horns that the gender of a crab is recognized. The eyes of these creatures are sensitive to changes in light.

The large eyes of these crabs give them a wide field of vision. The eyesight of these creatures is very good. This helps them spot predators very quickly and find out any other threats.

It is about 2-3 inches in size.

It has a water-tight exoskeleton (external skeletal structure) which prevents the creature from becoming dry. The body covering also lends support to its muscles and organs.

Shell Shedding

With increasing maturity, the crab begins to lose its external skeleton. It comes off at a point, only to be replaced by a new, slightly larger shell. The new shell takes some time to harden and until that happens, the crab remains vulnerable.

This creature is found in sandy beaches of tropical as well as subtropical coasts. It can be found anywhere from the American Atlantic Sea, the Mediterranean Sea and the Red Sea to coasts along the American Pacific and the Indo-Pacific.

These crabs are usually found in sandy beaches and backshores where they live in burrows. Crabs usually burrow a deep hole to keep themselves cool during the daytime. They remain in burrows during daytime and when winter is at its coldest.

It is omnivorous, meaning it feeds on both animals and plants. It can also devour other crabs and detritus. The creature feeds on snails, clams, turtle hatchlings, lizards and small crabs. Ghost Crab foods also include organic matter.

Characteristics

Ghost Crabs

Source – umces

This is an exceptional creature that possesses the unique ability to store oxygen in airbags located close to its gills. When the creature buries itself in the sand during winter hibernation, it survives on this stored oxygen.

The crab can move on the sand at about 10 miles per hour and is able to change is direction suddenly.

It burrows into the sand at a 45-degree angle for a depth of up to 4 feet. It creates holes of 1-2 inch width. Adult crabs of this family occasionally dig a burrow with two entrance shafts.

The digging activities of these crabs have been reportedly heard even 2 meters (6.5 ft) away.

Ghost crabs generally look for food at night. This is also the time when they dig and repair their burrows. They search beaches for any animal or plant that has been washed ashore. It is rare to see these crabs during daytime as they are mainly active during the night.

Mature male ghost crabs neatly pile the burrowed sand next to their entrance. Young and female crabs do not make a neat pile and the sand they dig out is scattered in all directions beside their entrance. Female crabs can identify a male residence by the neat sand pile and get a mate for themselves.

Younger crabs burrow and make homes in the area of shore that is closer to water. Older crabs are seen to burrow away from water.

These crabs can make three types of sounds, by stroking their right claw on the substratum of their leg, by rubbing their legs together and through their gill chamber.

The animal breathes in through its gills. They periodically make their gills moist with seawater. The gill chamber produces bubbling sounds that can be heard by people who go for tanning at the beach.

The creature retreats to the ocean while laying eggs. The eggs of this creature turn into marine larvae.

This crustacean communicates through sounds with other members of its family. The creature has a unique mechanism on its right claw known as a Stridulating organ. When it strokes this against the bottom of its leg, a squeaky noise is produced. A crab produces this noise to warn other crabs not to enter its burrow. Male crabs also use this sound to attract female mates.

Ghost Crabs can make very good pets if properly looked after. If you are planning to breed these crabs in your home, here are some steps that you have to follow.

  • Get a tank of about 20 gallon size. If you want to keep over four crabs in only one tank, it is advisable that you buy one of larger size.
  • Fill half of the Ghost Crab tank with thick sand.
  • Keep little shells, rocks and small plants in the tank. This will recreate an atmosphere similar to a sea shore and keep your crabs entertained!
  • Sift the sand with a small branch or sifter to keep the contents of the tank clean. Do this once every week to rotate fresh sand. The more the crabs you have in the tank, the more frequently you should rotate the sand.
  • Use clams and oysters or even old vegetables and fish to your crab. Repetition in diet can tire your crabs and make their survival difficult. Try to find out which foods your crab like. Feed that often to your crab and also balance it with other foods.

Reproduction

Female crabs of this species have a rounded abdominal flap. Thousands of eggs are incubated inside the flap. These are freed into the sea after being matured. The eggs mature into larvae at sea after over two months and then return back to the shore.

Studies have shown the density of Ghost Crab harvesting to be around 3000-5000 every km every year.

Know some of the most interesting facts associated with these creatures.

  • These crabs can hold oxygen in their air sacs for about six weeks.
  • It wets it gills for two purposes, reproduction and respiration. Occasionally, the crab draws up water from moist sand to moisten its gills.
  • The strong hairy legs of this animal make it run very fast and achieve speeds of about 10 miles per hour. This makes this crab the fastest among all crustaceans.
  • The crab has club-shaped eyestalks and it boasts of a 360° vision. This helps it see and catch insects that are even in mid-air.
  • It has the exceptional capability to shrink back its eyes into grooves located on the frontal area of its shell.
  • Contrary to what many think, these creatures cannot swim in water. However, female crabs can keep themselves afloat by turning upside down in water. This is done to let the egg mass under their abdomen respire freely.
  • Occasionally, the crabs go out into the sea to protect themselves from predators such as raccoons and birds .
  • They devour baby turtles while they hatching out in the sand. The crabs drag the baby turtles into their burrows and eat them up.
  • Crabs of this species usually engage in a combat that is non-contact. The combat style is more ritualistic in style and ends in contact in very rare cases.

This crab changes its pace as its speed increases. It can walk for an indefinite period of time on four pairs of legs. At very high speed, it raises its fourth pair off the ground. At highest speed, it uses only the first two pairs of walking legs to keep running.

yes, we study bird nest productivity on our Florida State park beaches and ghost crabs have been documented in eating snowy plover eggs,chicks and make attempts at eating adult plovers. They also eat least tern eggs and harass least tern adults on nests. We have some footage on youtube looking at defense mechanisms feigning broken wing to lure ghost crabs away from snowy plover nests.

Question about sand crabs – we have been watching them all week at a NC beach. However, last night there were none to be found. It is close to a full moon – does this have any impact on them? All other nights have been cloudy. If not, any idea why they would be out one night and not another?

My husband and I found one on the coast of Galveston over labor day weekend. It was a pregnant female. She had her thousands of larvae last night. Would love some advice on how to care for all the larvae. We have an established 100 gallon saltwater tank and would hate to put all the larvae in there with all the fish.

It’s interesting to hear that this crab is nocturnal. My husband and I have been frequenting the Playalinda Beach near Titusville Florida, and this last month we have been watching many many ghost crabs during the day. We are absolutely fascinated by them! They display all of the characteristics and activities that you mention. We have seen one baby that is almost minuscule and is already displaying the exact behavior of burrowing out its hole. From our chairs we can sometimes see six or seven of them at a time within our vision. They are very very cautious and can move like lightning. We took a video with our phone that shows a crab flinging its load of sand away from its hole. Very entertaining creatures. Thank you for this interesting information.

Came on here to find more info.

We live near a protected barrier island, and enjoy taking our small whaler out to spend part of a beautiful day, to walk the sandy beach that extends about 20 undeveloped beautiful miles, sit and watch waves without people except for the usual few surfers, locals, and visitors. I saw this crab, who appeared to be alive, with so much color and very large, yet was not moving. I took a photo of it and sent it to the island’s preserve group who studies and protects the island’s wildlife. It is apparently a ghost or sand crab. I could not believe they shed their exoskeletons! It looked larger than one of the normal N. C. sized crabs, but now I know why it looked alive yet was not, nor was it inside it’s body at all, not dead, just the shell left behind. I can attach a photo if you are interested. Thanks for the information on your site that they actually recommended to me, from the Masonboro Island Reserve.

Thank you Debbie! It would be helpful if you’d attach a photo or two of the exoskeleton that you saw.

Introduction

You will probably only catch a quick glimpse of this fast-moving crab as it races across the sand and disappears into a burrow.

Identification

The Ghost Crab is relatively small and, being almost translucent with flecks of pink and yellow, it is well camouflaged against the sand. If you manage to see one up close, you will notice its eyes are on the end of long stalks.

Ghost Crabs live on intertidal beaches.

Distribution

Ghost Crabs are found in tropical waters, from the Kimberley in Western Australia, Northern Territory, Queensland to Sydney, New South Wales.

Other behaviours and adaptations

The Ghost Crab stays in the cool protection of its burrow by day and scuttles down to the water at twilight to hunt. The burrow, which is built quite high up on the shore (sometimes over 100 m from the sea), can be over 1 m deep.

Brief Overview of  Ghost Crabs 🦀

First described in 1860, the ghostcrabs have remained on our planet virtually unchanged since the Quaternary era, after the disappearance of the dinosaurs, evolving along with the first humans. Their presence is considered an indicator of healthy beaches, since they are particularly sensitive to chemical pollutants such as oil derivatives.

However, the main danger they face in tourist places relies in the destruction of their habitats by urbanization and  the continuous walk of people, which prevents them from eating and build their underground dens.

The Ghost Crabs’ Main Characteristics 🦀

Ghost crabs’ anatomy 🦀.

There is a wide variety of ghost crabs, so depending on the species may differ in their general characteristics. Their sizes range from a few millimeters, up to four meters wide when their legs are extended.

These decapods have a thick exoskeleton composed of highly mineralized chitin, four pairs of legs, a pair of claws and elongated and swollen peduncles that can swivel 360 ​​degrees.

Their carapaces are usually deep and have a square shape. The types of ghost crabs can be identified more easily by means of the area where they are found.

We can mention the O. quadratus , which inhabits the western Atlantic coast from New Jersey to Brazil , the O. ceratophthalmus, found on the beaches of the Indian and Pacific oceans a nd the ghost crab O. saratan, belonging to the Red Sea .

Other distinctive features 🦀

Ghost crabs emit a unique bubbling sound when they strike with their claws on the ground and rub their legs. Their scientific name, Ocypode means «fast feet», since they often move at a speed of up to 10 miles per hour.

When ghost crabs breathe oxygen, they need to keep their gills wet, so it is common to see them ingesting seawater or absorbing moisture from wet sand. As for their diet, it consists mainly of sea turtle hatchlings, turtle eggs, clams, insects and other crabs .

Now…. let´s watch them

The Ghost Crabs’ Common Habitats 🦀

Ghost crabs live in small burrows in the sand , preferring a solitary life with only one crab per burrow.

Such places are commonly dug at a 45-degree angle a nd can be up to 1.5 meters deep . They create their burrows with angled entrances so that the breeze blows in them, allowing the ghost crabs to be ventilated.

How  Ghost Crabs Reproduce? 🦀

Ghost crabs, (like most crabs), depend on the sea to perpetuate their species . During mating, the male ghost crab deposits its «genetic material» into the female, holding its claws tightly.

After a quick and unpleasant encounter with the male, the female is released and fled to her burrow, maturing her eggs in her body and depositing them shortly after in the sea, which will later return in the form of larvae and live buried in the sand until they  reach their adulthood.

From time to time they must dispute their food among themselves, which makes them fight and use their powerful pincers.

There are rarely deadly duels, but it is very common for them to lose a leg or a pincer during the fight .

Fortunately, they can recover such limb when they molt their exoskeleton . Since this is an external structure it just can´t grow, so the ghost crabs ( as most crabs)periodically grow a new one underneath, discarding the old one and growing a little more while the new «exoskeleton» hardens.

Unfortunately for them, that exoskeleton is not hard enough to withstand the stomp of a scared or distracted tourist.

let´s have a final look of them

How To Catch Ghost Crabs And Can You Eat Them?

Venture to the beach as night falls for a chance to spot a ghost crab.  How to catch these ghost crabs proves to be harder than it looks. With lightning-like reflexes, these sand-colored crabs dart across the beach and into the ocean in mere seconds.

Ghost crab hunting is a favorite among beachgoers to the Atlantic coast as capturing these speedy crabs proves to be a hilarious challenge.

Guide To Ghost Crab Hunting

What Is A Ghost Crab

The Atlantic ghost crab is small iridescent species of crab that is found along the Atlantic coast. It has been found as far north as Block Island, RI to Santa Catarina, Brazil.  There are many different ghost crabs around the world; this article will focus on the Atlantic ghost crab.

Ghost Crab Hunting

Burrows can be up to four feet deep and are often found hundreds of feet from the water’s edge. They can even be closed up with sand to keep the crabs cool in the heat. Younger ghost crabs burrow close to the sea, while older ghost crabs burrow higher up on the beach.

Beaches that experience a high volume of visitors are less likely to see ghost crabs as many are crushed from foot and vehicle traffic while in their burrows. In addition, pick up litter found on the beach. Litter washed from streets or left directly on the beach can trap and kill the crabs.

We learned all about these amazing creatures during our visit to Garden City, South Carolina .

Packing List For Ghost Crabbing

What Do Ghost Crabs Eat

Ghost crabs are omnivorous, feeding on insects, filter-feeders (like clams and mole crabs), and the eggs and hatchlings of loggerhead turtles. They will also scavenge for vegetation and detritus.

Fun Ghost Crab Facts

  • The Ghost Crab scientific name, Ocypode, means “fast feet,” as they’re often seen darting sideways at up to 10 miles per hour.
  • Ghost Crabs make a unique bubbling sound by hitting their claws on the ground and rubbing their legs together.
  • While the Ghost Crab breathes oxygen, they must also maintain plenty of moisture in their gills. They do this by acquiring water at the edge of the gulf or getting moisture from damp sand.

Can You Eat A Ghost Crab?

No. Unless you are seabird I wouldn’t recommend it.

How To Catch Ghost Crabs

What You Will Find On The Beach At Night

While there may be brave souls who will attempt to pick the crabs up with their bare hands, I recommend against this because they will pinch!

Walking closer to the water always yielded the most ghost crab sightings before they scamper away into the sea or back into their “crab holes,” as my daughter would say.

Larger crabs can found further from the water while smaller ones hang closer to the water’s edge.  Once the light hits the crabs, they will often freeze for a few seconds before moving. Just like a deer in headlights.

We found that tossing a little sand on them would relax them just long enough to scoop them up in our nets. Try to approach the crabs from behind if possible so, they don’t scurry away.

Consider using a sea turtle safe light while on the beach or a flashlight with a red light. Headlamps are another excellent tool for ghost crab hunting as it allows for two free hands to maneuver the net. After carefully scooping up the crab, place it in the bucket.

It is fun to see how many each person can get before setting them free. However, the true belly-laughs come from dumping the bucket of crabs at the end and watching fancy footwork paired with loud squeals of excitement and horror. It’s hilarious when a crab darts over someone toes!

Since Ghost Crabs are not for eating, it is more like Ghost Crab catching verse Ghost Crab hunting. Be sure to release all your Ghost Crab friends not long after you capture them.

Tips For Ghost Crab Hunting

Ghost Crab hunting tips

  • Make it an educational event in addition to a fun activity. Teach children about the wildlife they encounter during a visit to the beach so they know what to expect and have a better appreciation of the world around them.
  • Use a five-gallon bucket to collect your crabs if possible. Crabs are master escape artists and can easily get out of small sand buckets. Especially the larger crabs.
  • The best time for ghost crabbing is between May and September.
  • Wear darker colored clothes as camouflage. Ghost crabs are always on high alert for predators.
  • Please be careful with the crabs and free them quickly so they can get back to their hunt for food and remoisten their gills to keep breathing.

Additional Resources

What To Pack : Flashlight or headlamp, a net, a large bucket, and a little bit of courage.

Atlantic Ghost Crab Facts (Ocypode Quadrata)

Last updated on August 27th, 2022 at 06:27 pm

A ghost crab, also known as mud crab, blue crab , or shellcracker, is one of many species in the Ocypode genus of crabs that are found in the western Atlantic Ocean and inhabits muddy bottoms in the salt and brackish waters of North America, Europe, and Africa.

The Ocypode quadrata has two color phases that are based on the location of their burrows; they are either light-colored like soil or dark-colored like fresh leaves. This adaptation allows them to hide more effectively from predators and prey alike.

It is a small species of crab found in shallow waters off the coasts of North America, Europe, and Africa. It can be distinguished from other crabs by its distinctive coloration and elongated pincers which have tiny hooks at the tips to aid in gripping prey. Ghost crabs, as they are commonly known , are often seen on sandy beaches at night, particularly when there are no high tides or storms to ruin their feeding grounds with seawater.

It was originally thought to be part of the family Ocypodidae , but molecular studies show that it is part of the Xanthidae , an entirely different family of crabs. The Atlantic ghost crab favors muddy or sandy bottoms, and can be found as deep as 50 meters below sea level.

They live in the shallow waters of the western Atlantic Ocean and along the eastern coast of North America. The crabs are found from North Carolina to Florida, Bermuda, and the northern Gulf of Mexico and as far south as Brazil’s Paraíba coast in the Atlantic Ocean and Colombia’s Caribbean coast in the Pacific Ocean.

What is a ghost crab?

Atlantic ghost crab

The Atlantic ghost crab, Ocypode quadrata, is a species of crab from both east and west coast of North America. Most commonly found on sandy beaches, it has adapted to life in shallow waters that are exposed to high amounts of light. It gets its name from its ability to disappear by flipping its body over when disturbed, leaving only two pairs of legs visible.

It also has an unusual talent for regenerating limbs after they have been lost due to injury or predation; however, there have been cases where ghost crabs have not regenerated one or more limbs, resulting in bilateral asymmetry. They can be found along beach shores from southern Canada to central Mexico and many off-shore islands including those off of Nova Scotia, Baja California Sur, Puerto Rico and Bermuda.

Ghost crab description and origin

Ocypode quadrata, also known as sand crabs, are found on both sides of North America. They live in shallow waters and sandy beaches, usually less than three feet deep. They thrive in areas where there is access to both land and sea.

They may look like a spider with their eight legs, but these animals are crustaceans just like crabs, lobsters, and shrimp that have an exoskeleton. Unlike crabs, however, which have two larger claws for prying open shells and pinching off pieces of food, they can only pinch off smaller pieces because they do not have larger claws. They also use strong jaws to tear through flesh from dead fish or other marine life; it’s one of many natural decomposers at work in ocean habitats around the world.

Ghost crab scientific name

The scientific name of the Atlantic ghost crab is Ocypode quadrata

Ghost crab habitat

If you’re thinking about adding some ghost crabs to your saltwater tank, it might be important to know where they come from. They are a species native to tropical waters along North and South America. They prefer coastal environments and can be found in mudflats and estuaries as well as mangrove forests.

Ghost crab size and weight

They can grow to be about 3 inches (8 cm) wide at maturity and weigh around 2.5 ounces.

Ghost crab adaptations

Atlantic ghost crab

Ocypode quadrata are generally nocturnal, hiding away in moist crevices during daylight hours. They have relatively short pincers, at only 0.9 in (2 cm), but they do have long pedipalps that can be used to assist with smell and touch. Their front legs are longer than their back legs, which helps them move faster, as well as helping them protect themselves by hiding within larger rocks or driftwood piles. While these crabs can appear quite large due to their carapace widths of up to 6.3 inches (16 cm), they typically grow no more than 3.1 inches (8 cm).

The two eyes on each side of a ghost crab’s head give it excellent lateral vision while its poor depth perception means it won’t easily flee if a threat is approaching from behind. This makes it a very effective predator of smaller organisms like sea anemones and sponges, both of which lack depth perception as well.

Why are they called ghost crabs?

  • The name ghost crab comes from its ability to blend into its surroundings; when you walk past them you may not even notice them until a leg or claw pokes out from under a piece of seaweed or beach detritus.

The most obvious explanation for a name like ghost crab is that it’s just plain creepy. But there’s more to it than that. They are called ghost crabs because they have pale, translucent exoskeletons and live in burrows at high tide—perfect for causing all kinds of confusion for unwary beachgoers, who might mistake them for otherworldly spirits or zombies. Also, their movements look like slow-motion time-lapse photography. It really is an apt name.

A popular myth tells of someone stepping on one, which looks dead but isn’t; when the foot comes down again, he crushes both his own toe and his dinner. Like any good myth, though, there are several variations on exactly how it plays out: sometimes a leg gets squished instead of a toe; sometimes people think they’ve stepped on one only to find that what was squished wasn’t a ghost crab after all!

What do ghost crabs eat?

They are omnivores, so they consume a variety of items. The most common foods in their diet include fruits, seaweed along with algae and plankton that are washed up on shore, and carrion. And occasionally small snails, such as Littorina littorea , they also eat other invertebrates, such as dead fish. They’re also scavengers that will eat whatever is in front of them if they’re hungry enough, meaning they’ll often consume meat scraps from seafood restaurants.

Ghost crab life cycle

Atlantic ghost crab

Their life cycle starts with courtship. After mating, females lay their eggs in long strings and then bury them in sand or gravel. Most ghost crab species protect their eggs by covering them with debris to hide them from predators, but some females, instead, choose to remain with their eggs until they hatch.

The female will then care for her young for several weeks after they have hatched. Ghost crabs are preyed upon by birds, fish, mammals, and other crustaceans. As a result, it is common for crab parents to abandon their nest immediately after hatching; once mature, ghost crabs prefer to live on dry land away from predators.

The average lifespan of a wild ghost crab is three years, although many captive individuals may live longer than ten years when protected from predators and parasites. Ghost crabs require very little water throughout most stages of their lives; they obtain all necessary moisture through food sources alone.

Are ghost crabs aggressive?

Yes, ghost crabs are aggressive. They’re a territorial species, and they’ll attack other ghost crabs that enter their territory. Most often, fighting occurs during mating season or when males challenge one another for a large food source. As with any crab, it is possible to take two males from separate territories and place them in an aquarium together—provided you give them plenty of space and hiding places.

Ghost crab lifespan

Their average life span is 3 to 4 years. Female crabs live slightly longer than males because they have a slightly higher body fat content that provides energy in case of prolonged molting or pregnancy. Large crabs die sooner than small ones because they require more food and their shells can’t withstand so much pressure before cracking.

Ghost crab predators

There are few known predators, but seagulls and foxes will eat them if they can catch them. Like other crabs, they do not die easily. If a crab is attacked by a bird, it will pull its appendages into its shell and block off any possible entrances. The bird may be able to peck through the shell, but unless it has sharp claws or a beak that can grip onto hard material, like plastic or rock, ghost carb will usually give up after a short time.

Are ghost crabs good eating?

Like other crabs, they are edible when cooked, but people rarely eat them. They’re sometimes sold in Asian markets as part of a mixed seafood dish, where they are boiled and eaten whole along with their legs and claws. Outside of Asia, ghost crabs aren’t widely eaten. If you’re interested in trying them yourself, your best bet is to cook them on their own rather than as part of a mixed seafood dish or some other recipe. Doing so will allow you to fully appreciate their unique flavor and texture.

Are ghost crabs dangerous?

They’re not dangerous to humans, but ghost crabs can be a nuisance when they sneak into homes. Fortunately, there are several effective ways to prevent these crustaceans from creeping in.  For example, you could simply seal any cracks or holes that might allow them access to your home.

If you have an outdoor pool or spa, make sure to keep any drains covered with wire screens. Another option is installing motion-detecting lights at your windows and doors—these will scare away most crabs if they approach during dark hours

Can ghost crabs be pets?

Although there are plenty of animals that make good pets, ghost crabs are not among them. These solitary arthropods have special adaptations to living and hunting on land, but they still need access to a saltwater habitat where they can lay their eggs. If you’re looking for an exotic aquatic pet instead, there are many others available—but be sure that your local laws allow pet ownership before you bring home a wild animal.

Ghost crab facts

Atlantic ghost crab

  • The ghost crab’s back and claws are covered in light-sensitive cells called ommatidia, which it uses to detect movement and light. This helps it hunt for food at night—its natural hunting period.
  • Ghost crabs can be easily identified by their light grey color with white spots on their claws, legs, and shell.
  • Because they don’t have real eyes, they rely on these white spots to detect predators that might be approaching.
  • The two most common species of ghost crabs are found off both North American coasts: one inhabiting intertidal zones and sandy beaches of Massachusetts, Maine, Rhode Island and Connecticut; and one along North Carolina coastlines down to Georgia’s barrier islands.

This incredible adaptation not only aids them in evading predators but also enhances their efficacy as hunters, whether it be foraging for the diverse array of food sources available to them or strategically capturing prey.

These funny, little guys exhibit remarkable versatility within their behavioral repertoire, engaging in a wide range of activities from digging intricate burrow systems to displaying fascinating social interactions within their colonies.

We can get a deeper understanding of the ecology and importance of these captivating crustaceans as we dig into their habit. As we journey into the world of ghost crabs, prepare to be amazed by the complexities and wonders of these enigmatic creatures.

What’s So Special About Them?

These little crabs are fascinating creatures that catch the eye of beach goers and marine enthusiasts alike. One of the most captivating features of these crabs is their ability to blend in with their sandy surroundings.

This incredible camouflage not only protects them from predators but also allows them to sneak up on their prey with ease. Unfortunately though, their prey is often baby sea turtles who already have an uphill battle for survival.

Another remarkable trait is their speed. These little guys are known for being incredibly fast runners, able to sprint at speeds up to 20 km/h!

They accomplish this through their unique sideways gait, which allows them to move quickly while still remaining low to the ground. This speed, combined with their amazing camouflage, makes them efficient and elusive hunters.

Ghost crabs are also equipped with an interesting set of eyes. Their two large, stalked eyes can rotate 360 degrees, giving them a panoramic view of their environment. This allows them to keep a watchful eye on potential threats while also surveying the landscape for prey.

In addition to their physical adaptations, ghost crabs are nocturnal creatures, venturing out after sundown to scavenge and hunt. They are often seen scurrying along the shoreline, leaving intricate tracks in the sand as evidence of their nighttime activity.

Finally, ghost crabs have an amazing ability to “breathe” both on land and underwater. They possess gills for breathing in water, and specialized structures called branchiostegal lungs, allowing them to extract oxygen from the air.

This remarkable adaptation enables these crabs to thrive in the ever-changing environment of the intertidal zone.

Scientific Name and Sand Crab Comparison

What is the scientific name for ghost crabs.

Ghost crabs often referred to as little white crabs belong to the genus  Ocypode  within the family Ocypodidae. There are around 20 ghost crab species found around the world, and one of the most common species is  Ocypode quadrata , also known as the Atlantic ghost crab.

Are They Sand Crabs?

While ghost crabs are also referred to as sand-colored crabs, it’s essential to note that they are not the same as mole crabs.

Sand crab is a general term, including various crustaceans living in sandy habitats. Yes, ghost crabs can be considered a type of sand crab.

How Do They Compare To Mole Crabs?

In comparison to mole crabs ( Emerita ), these crabs display some differences. Mole crabs are small, rounded crabs with no visible legs, residing in the swash zone of sandy beaches.

On the other hand, ghost crabs are larger, agile, and possess visible legs, which allow them to quickly scuttle across the sand.

Mole Crabs :

  • Small and rounded
  • Live in the swash zone
  • No visible legs

Ghost Crabs :

  • Larger and agile
  • Live in burrows
  • Possess visible legs including four pairs of walking legs

Stone Crabs?

Ghost crabs are not related to stone crabs. Stone crabs ( Menippe  spp.) belong to a different family, Menippidae, and are known for their large, strong claws.

They inhabit rocky shores and estuaries, while ghost crabs prefer sandy habitats.

Appearance and Location

These fascinating creatures are known for their unique appearance and quirky behaviors. Let’s take a closer look at the physical attributes and the locations where they can be found.

What Color Are Ghost Crabs?

Ghost crabs display a wide range of colors, typically blending in with their surrounding environment. Their colors can range from a sandy or light brown to a pale yellow or gray.

They might even have hues of blue or green, depending on their specific environment and light. Young ghost crabs are much darker than adult ghost crabs.

How To Tell The Difference Between Male and Female Ghost Crabs

Male ghost crabs are larger than females and have one claw larger than the other. See pic above.

Where Can You Find Ghost Crabs?

Ghost crabs can be found up and down the Atlantic Coast and on many East Coast Beaches. During the summer months you will find them on the white sand beaches including those up north in Rhode Island to North Carolina’s Outer Banks down along both sides of the Sunshine State’s Coastline. 

Younger ghost crabs burrow closer to the water’s edge while older ghost crabs burrow higher on the beach. Another interesting fact is the female deposit their fertilized eggs near the surf line.

This allows the winds and tides to help the little guys find something to latch onto as they grow.

Are There Ghost Crabs In Florida?

Absolutely! Ghost crabs can be found throughout the coastal regions of Florida and on both the Atlantic Ocean side of the state and the Gulf Side.

They are commonly found on sandy beaches and dunes, especially in those areas with a significant amount of vegetation. Often in a small hole you might overlook if you aren’t paying attention. 

Where Can I Find Ghost Crabs In Florida?

Ghost crabs can be found on many beaches including:

  • Panama City Beach:  One of Florida’s Panhandle coastal beaches, Panama City Beach, is a go-to spot for observing ghost crabs scuttling along the shoreline.
  • Henderson Beach State Park : Along with other local wildlife, located near Destin on Florida’s Gulf Coast, this state park is a great spot on the Panhandle to find ghost crabs.As you walk along the beach, watch for movement on the sand from the corner of your eye.
  • St. Augustine Beach:  With a rich history and a lengthy stretch of shoreline, St. Augustine Beach offers an ideal environment for ghost crabs to thrive.
  • Siesta Key:  In addition to its crystal-clear waters, Siesta Key’s pristine sand creates the perfect habitat and is a great place to search for ghost crabs.

Remember that these creatures are nocturnal, making nighttime the best time to spot them moving about with a flashlight.

One Ghost Crab Per Damp Sand Burrow

Ghost crabs are known to occupy damp sand burrows, which they create to escape the sun, predators, or seek shelter during high tide. Each burrow is unique, as it is built by a single crab using its powerful claws.

The burrows can be found scattered along the beach in areas where the sand is moist enough for them to dig. It’s not uncommon to come across these distinct holes that serve as a ghost crab’s humble home.

Interactions with Humans

Can ghost crabs hurt you.

Ghost crabs pose little to no threat towards humans as they are non-aggressive creatures. While their snapping claws might look intimidating, they usually use them for digging burrows and catching prey.

In a rare situation where a ghost crab might feel threatened, it could pinch a human, but the pain would only be mild and short-lived. But you should be careful and respect the crabs’ natural habitat by not intentionally provoking them or disrupting their burrows.

Are Ghost Crabs Good To Eat?

Although ghost crabs are not poisonous, they are generally not one of the top choices for a crab dinner. Compared to larger crabs, their meat is minimal and not as flavorful.

Ghost crabs have a primarily nocturnal lifestyle and feed on various small creatures like insects, smaller crabs, and even sea turtle eggs. Due to their diet and small size, they are not commonly found on plates.

Some cultures do enjoy consuming ghost crabs, especially in coastal regions where they are abundant. The crabs are usually boiled or steamed, similar to the cooking methods for other edible crab species.

For those who decide to give this seafood option a try, it is crucial to catch the crabs sustainably and responsibly to avoid causing harm to the local ecosystems that often include sea turtle nests.

Ghost Crab Hunting

Where can you go ghost crab hunting.

Ghost crab hunting is an exciting activity for the entire family, and it can be done on various beaches across the globe.

These little friends are nocturnal creatures are commonly found along the shores of the Atlantic, Pacific, and Indian Oceans.

Some popular locations for ghost crab hunting include the East Coast of the United States, the Gulf Coast, and Australia’s sandy shores.

What Do You Need To Take With You When Ghost Crab Hunting?

You want to be prepared and ready to enjoy your ghost crab hunting experience. That means the right equipment.

The best way to catch them is to be aware of their nocturnal habits, and hunt at the right time of day or should I say night.

Here are a few essential items to have with you:

  • A large bucket or container : To gently hold the ghost crabs you capture.
  • A small net or scoop : A tool that helps you catch the crabs without hurting them.
  • Comfortable footwear : For walking along the beach and protecting your feet from sharp objects.
  • Appropriate clothing : Light, breathable clothing that can get wet or sandy is a good choice.
  • A sea turtle-safe flashlight : More on this in the next subsection.

Why You Should Use A Sea Turtle Safety Flashlight/Red Flashlight

When ghost crab hunting at night, it is crucial to protect the local sea turtles by using a sea turtle-safe flashlight , also known as a red flashlight. This type of light has two essential benefits:

  • Protecting sea turtles : Sea turtle hatchlings rely on the natural light from the moon to navigate their way to the ocean. Bright, white flashlights can disorient them, leading them away from the sea and into danger. A red flashlight ensures the hatchlings can safely make their journey.
  • Preserving night vision : Red light does not disrupt human night vision as much as bright, white light would. Using a red flashlight allows for better visibility of the surroundings without disturbing your night vision – making it easier to spot the elusive ghost crabs.

Ghost crab hunting can be a fun adventure that gives you a chance to observe these fascinating creatures in their natural habitat.

Grab your gear and head to the nearest beach. With a little bit of patience and luck, you may be able to catch these small crabs with fast feet for a fun experience the whole family will enjoy.

Ghost Crabs live on tropical beaches

Ghost crabs are known as sand crabs.

Ghost crabs are also known as sand crabs. They are tiny animals that are mainly terrestrial. They live in elaborate burrows. Sand crabs live their entire adult life on beaches in tropical and subtropical regions around the world. They prefer quiet beaches and forage for food at night when they are less apt to be seen by predators.

where Ghost crabs live

Sand crabs are found along beaches from Rhode Island south to Brazil. Unlike crabs that live in the water they only need to wet their gills. In Chesapeake Bay these crabs like to brace themselves in the sand and let the waves wash over their bodies to wet their gills. They also have hairs on the base of their legs that wicks up water from damp sand to wet their gills.

What ghost crabs eat

Ghost crabs are omnivores because they eat meat and vegetable matter. They eat all kinds of food they find on the beaches. Their diet includes vegetation and other debris washed in by the tides. They also feed on mole crabs, clams and the eggs of loggerhead turtles.

Predators of these tiny crustaceans include raccoons, shorebirds and gulls. Sand crabs hide in their burrows during hot sunny days. They stay in the burrows for two reasons during the day. They stay inside their burrows during the day when the hot sun heats up the beaches. It is also much harder for predators to see the tiny crabs at night than it is during daylight hours.

Ghost crab live in burrows

Ghost crabs all live in burrows that have a small opening about the size of a nickel or a quarter. They burrow down into the sand often creating an elaborate tunnel system underground. Their tunnels often go down four feet into the sand with side branches. Young sand crabs create burrows close to the water’s edge while older adults often create burrows hundreds of feet from the edge of the waves.

mating and reproduction

Sand crabs mate all year long and the males prefer to mate near their burrow holes. During the mating time with a female the male secretes a fluid that hardens and prevents rival male’s sperm from reaching the ova of the female. The female carries the fertilized eggs under their bodies until they are ready to hatch. She releases the eggs into the water where the larvae grow and develop into young crabs before coming ashore to live the rest of their lives.

Physical Features

Ocypoda is the Latin name for ghost crabs. It means “swift-footed.” The crabs have four sets of walking legs and one pair of white claws. The adult’s carapace (shell) is usually about 2 inches long. Young crabs are much darker with a mottled gray or brown shell. Older adults have shells that are square-shaped and semi-transparent. The males are usually larger than the females and their shells can grow up to 3 inches long. They have eyestalks that are club shaped. The crabs can rotate the eyestalks 360 degrees looking for predators and food.

What is the diet of a ghost crab?

Introduction to ghost crabs.

Ghost crabs are fascinating creatures that inhabit sandy beaches and shorelines. They receive their name from their translucent exoskeletons and their quick movements, which make them appear almost as ghosts. These nocturnal creatures are active mainly during the night when the temperatures are lower, and they can be observed scurrying around on the beaches in search of food.

Habitat of Ghost Crabs

Ghost crabs can be found in a wide range of habitats, from tropical to temperate climates, and from the intertidal zone to the dune crest. They are usually found on sandy beaches, where they dig burrows in the sand to protect themselves from predators and extreme weather conditions. Ghost crabs prefer to live in areas that are free of human activity, and they tend to avoid disturbed or polluted beaches.

Physical Characteristics of Ghost Crabs

Ghost crabs have a unique appearance that distinguishes them from other crabs. They are small to medium-sized, with a carapace that ranges from 1.5 to 10 centimeters in diameter. Their legs are long and slender, and they have sharp claws that they use for hunting and self-defense. Ghost crabs have two pairs of eyes, one for spotting prey and one for detecting predators. Their translucent exoskeletons are well adapted to their sandy habitats and provide camouflage against predators.

Feeding Habits of Ghost Crabs

Ghost crabs are omnivores, which means they eat both plant and animal-based foods. They are opportunistic feeders that will consume anything they can get their claws on. Their diets are mainly influenced by their habitat and the availability of food. Ghost crabs are scavengers that hunt at night and forage during the day. They have a keen sense of smell and can detect food from a distance.

Why is the Diet of Ghost Crabs Important?

The diet of ghost crabs is important because it helps sustain their populations and contributes to the overall health of their ecosystems. Ghost crabs play a crucial role in the food web of sandy beaches and shorelines. They prey on small animals and scavenge on dead organisms, which helps to clean up the beaches. Their burrowing activities also help to aerate the sand and promote the growth of vegetation.

What Do Ghost Crabs Eat?

Ghost crabs eat a variety of plant and animal-based foods, depending on their habitat and the availability of food. They have been observed feeding on algae, seaweed, fruits, and seeds, as well as fish, crabs, insects, and mollusks. Ghost crabs will also scavenge on carrion, such as dead fish or crabs.

Plant-Based Foods in Ghost Crab Diet

Plant-based foods in the ghost crab diet include algae, seaweed, fruits, and seeds. These foods are usually found in the intertidal zone or washed up on the beach. Ghost crabs have been observed feeding on the green alga, Ulva spp., which is common on sandy beaches.

Animal-Based Foods in Ghost Crab Diet

Animal-based foods in the ghost crab diet include small fish, crabs, insects, and mollusks. Ghost crabs use their sharp claws to catch and kill their prey, which they then tear apart and consume. They are also known to scavenge on carrion, such as dead fish or crabs.

Importance of Calcium in Ghost Crab Diet

Calcium is an essential mineral that is required for the growth and development of the exoskeleton in ghost crabs. Ghost crabs obtain calcium from their diet, primarily from the shells of mollusks and crustaceans. Without sufficient calcium in their diet, ghost crabs may develop weak or malformed exoskeletons, which can make them vulnerable to predators and other environmental stressors.

How Do Ghost Crabs Digest Food?

Ghost crabs have a simple digestive system that consists of a stomach, an intestine, and a rectum. They do not have a true digestive gland but rely on enzymes produced by the lining of their stomach to break down their food. The food is then passed through the intestine, where nutrients are absorbed, and waste is eliminated through the rectum.

Hunting and Foraging Techniques of Ghost Crabs

Ghost crabs use a variety of hunting and foraging techniques to find food. They are opportunistic feeders that will consume whatever is available. They use their keen senses, such as smell and vision, to locate food. They are also known to dig small pits in the sand to trap prey, such as small fish or insects.

Conclusion: The Versatile Diet of Ghost Crabs

Ghost crabs are fascinating creatures with a versatile and opportunistic diet. They play an important role in the food web of sandy beaches and shorelines, and their feeding habits help to maintain the health of their ecosystems. Their diet is influenced by their habitat and the availability of food, and they consume both plant and animal-based foods, depending on what is available. Overall, ghost crabs are important indicators of the health of their ecosystems and are fascinating creatures to observe and study.

what does a ghost crab eat

Are Ghost Crabs Edible?

Ghost crabs, also known as sand crabs or sand bubbler crabs, are edible, but they don’t supply as much meat as other crab species. They tend only to be a source of food for sea birds or raccoons; however, they may be consumed safely.

What Is a Ghost Crab?

Ghost crabs are crustaceans belonging to the family  Ocypodidae.  They are  quite smaller in size  compared to other crab species. On average, they measure about 2-3 inches.

Ghost crabs are found in coastal areas around the world, including tropical and subtropical regions. They  inhabit sandy beaches , mudflats, and intertidal zones, where they can find suitable conditions for survival.

These small crabs have a unique appearance that helps them hide on the sandy shores. They have a semi-translucent exoskeleton and their coloration can vary from pale yellow to gray or brown; this color allows them  to blend in with the sand.

They are  most active during the night.  They spend their days burrowing in the sand and emerge at night to scavenge for food. However, they can also be found during low tide, especially in areas where the tide exposes portions of the beach.

They are  very agile and fast , which allows them to swiftly navigate the beach and evade potential predators. They also actively sift through the sand, consuming microorganisms and detritus.

Species of Ghost Crabs

Here are a few common ghost crab species:

  • Ocypode ceratophthalma: This is one of the most widespread species found on the Atlantic coast and on the coastal beaches of the Indian Ocean and Pacific Ocean.
  • Ocypode gaudichaudii: Also known as the  horn-eyed ghost crab , this species is found in the Indo-Pacific and Eastern Pacific regions. It has distinct eyestalks with horn-like projections.
  • Ocypode quadrata: Found along the eastern coast of the U.S., from Massachusetts to Brazil, this species is commonly known as the  Atlantic ghost crab. 
  • Ocypode ryderi: This species is native to the western coast of the Americas, from Mexico to Peru. It is commonly known as the  Pacific ghost crab  or ryder’s ghost crab.

Can You Eat Ghost Crabs?

Technically you can eat ghost crabs, although you may not want to.  These crabs are relatively small and do not contain a lot of crab meat.

Moreover, ghost crabs are often found in sandy beach environments that may be exposed to various contaminants and pollutants . Eating ghost crabs sourced from these areas can be risky due to environmental contamination.

If you are interested in consuming these small scavengers, other types of crabs are more palatable for their larger size, meat content, and culinary value, such as blue crabs , Dungeness crabs, snow crabs, and king crabs .

What Do Ghost Crabs Taste Like?

People who have tried ghost crabs describe their meat as  bitter, bland and lacking distinct flavor.  These tiny crabs are not considered as flavorful or succulent as other crab species that are commonly consumed for their taste.

How to Catch a Ghost Crab?

Ghost crabs are usually active at night, so head to a sandy beach or shoreline during the evening or early morning hours for ghost crab hunting.

Once you locate one, approach it slowly and try to chase it down. Keep in mind that ghost crabs are fast and agile, so be prepared for quick movements.

A small handheld net with fine mesh can be helpful. Slowly lower the net over the crab, making sure to keep the opening of the net on the sand. Once the crab is inside the net, gently lift it off the ground and secure the opening to prevent the crab from escaping.

If you want to catch ghost crabs during the day, look for signs of fresh sand excavated from their burrows. Use a small shovel or your hands to dig around the entrance of the burrow. Be patient and gentle, as the crab might retreat deeper into its burrow. Once you spot the crab, carefully reach in and grab it from behind, being cautious of its pincers.

Remember, when catching ghost crabs, it’s important to handle them gently and carefully. I recommend releasing them back into their natural habitat once you have had fun catching one.

How Do You Cook Ghost Crabs?

Cooking ghost crabs, while possible, is not a common practice since they don’t contain a lot of meat. However, if you still want to cook ghost crabs, you can do so by following the below tips.

Rinse the crabs and remove  the triangular-shaped flap on the crab’s underside  (known as the apron), and discard it.

Bring a pot of salted water to a boil. Carefully  place the cleaned ghost crabs into the boiling water and let them cook for 8-10 minutes  or until the shells turn bright orange.

Once the crabs are cooked, place them in a bowl of ice water to cool down quickly. Once cooled,  use a crab cracker or a mallet to crack the shells and extract the meat . Discard the shells and any inedible parts.

Ghost crab meat is delicate and can be used in various recipes that call for crab meat. You can sauté the meat with butter and garlic, add it to soups or stews, or incorporate it into crab cakes or stuffing.

What do Crabs eat? (Full List!)

Ben Thomsen

What do crabs eat?

In the wild, crabs form an important part of the food web since they eat a wide variety of food items and provide a nutritious meal to many.

Crabs are omnivorous crustaceans that feed on particles, animals and plants found at the bottom of the ocean or in lakes. Marine crabs like the snow crab mostly eat other animals of the sea like shrimp, clams, starfish worms and snails. Freshwater crabs tend to live on smaller animals and plants by filtering the water.

The most common food items included in the natural crab diet are:

  • Shellfish like mussels, clams, crayfish and snails
  • (other) Crabs/crustaceans
  • Algae / seaweed
  • Carrion (dead animals)
  • Decaying plant and animal matter (debris)

Despite food items often being similar between different crab species, feeding strategies and behaviors differ substantially.

Some crabs prefer sifting through sand particles or filtering the water while others are active predators.

There are also differences in what time of the day different crabs eat.

Some are more active during the day, while others forage only at night. If you’re interested in learning more about the day/night rhythm of crabs, check out my post on how and when crabs sleep here.

Commercially, crabs are important in the sea-food market. While many commercial crab species are caught in the wild, other crabs (such as mud crabs and blue crabs) are bred in captivity. Additionally, they are often kept in captivity for research purposes or as pets.

Crabs kept in captivity are usually fed a consistent diet of only one or two food types , while wild crabs eat a wide variety of food . Crabs in captivity are often fed formulated foods, squid, mussels, fish, worms, brine shrimp, rotifers, and fresh fruit and vegetables.

Crabs are opportunistic feeders that will eat anything they can get. However, their diet depends largely on food availability.

Crab diets can change between seasons, as different food types become more abundant, or as they grow bigger and can handle larger food items. Cannibalism occurs in many crab species, either opportunistically, by feeding on dead crabs, or actively, by larger crabs killing and eating smaller crabs.

Common crab diets.

What do crabs eat in the wild?

Sea crabs eat shellfish , barnacles, shrimp, crabs, sea stars, worms, seaweed , plant matter, debris, and plankton .

While we often think of crabs as marine creatures, there are also many freshwater crab species found in tropical and subtropical areas.

Like most crabs that live in the sea , freshwater crabs eat both plant and animal matter but, obviously, there are different food sources in freshwater than in seawater.

Many of their food sources, like shellfish, worms, plant matter and debris, are similar to those of marine crabs. Freshwater crabs also eat insect larvae, small reptiles, frogs, frog eggs and tadpoles . 3

A crab’s diet largely depends on its size. Big crabs can handle larger prey items and crack open hard shells.

They also need more calcium and other nutrients to maintain their larger shells. Therefore, big crabs often prefer more nutrient-rich foods, like snails , crabs, sea stars, sea worms , and fish, while small crabs prefer smaller and soft-bodied food items.

Big crabs eat a larger variety of food than small crabs. Small crabs generally eat more plant-based foods, as well as microalgae, plankton, brittle stars, and shrimp.

What do hermit crabs eat?

Hermit crabs have a fragile shell and therefore use the empty shells of other creatures to protect them. Like most crabs, they have ten legs but only six are visible.

They use the other legs to hold on to their shell. In most hermit crabs, one pincer is larger than the other. They use the large pincer to handle and break open large food items, while the smaller pincer is used like tweezers to pick up small items. 1, 2

What do saltwater hermit crabs eat?

Saltwater hermit crabs mostly feed on decaying plant and animal matter.

They will use their pincers to scrape debris from rocks, or to scoop up sand to their mouth, where they carefully pick out food particles.

Their bushy antennae catch small food particles, like plankton and debris, which they remove with their mouth.

They will also browse on plants, seaweed, sponges, and sea squirts by plucking them with their pincers. Hermit crabs can also scavenge on carrion and some larger crabs will actively hunt for snails and other creatures.  

What do baby crabs eat?

what does a ghost crab eat

Baby crabs, like most smaller crab species, mostly eat particles floating around in the water or fish carcasses as they have a hard time hunting living prey.

All crabs start out their life as planktonic larvae. They go through several life stages before they become recognizable as crabs.

The small crabs (little crab larvae) are not large enough to prey on animals like their parents but will eat microscopic particles in the water like plankton, algae, and small worms. When they grow a bit bigger, they can start to hunt scavenge for

Even then, they need to go through several molts before they reach adult size. The small size of immature crabs comes with limitations to their menu.

This is true for most crabs, but particularly for the hermit crab is a particularly small type of crab, most of which never grows bigger than a golf ball in size. Hermit crabs eat more like the babies of larger crabs.

While adult hermit crabs eat a wider variety of food, juvenile hermit crabs are limited to smaller food particles such as debris, plankton, and microalgae.

Do big hermit crabs eat little ones?

It is quite normal for crabs to eat baby crabs of other, and even their own, species!

While cannibalism among crabs is generally common, cannibalism between hermit crabs seems to be rare in the wild , and colonies of different-sized crabs live together.

In captivity, however, larger crabs will sometimes injure or kill smaller crabs, especially when food, empty shells, or space is limited. This is also the case for most crayfish held in captivity .

While crabs often attack each other in the wild, it does not necessarily mean that they will eat each other. Although they may lose a limb or two ( which can grow back eventually! ), they often escape before the bigger crab gets the upper hand.

If molting crabs cannot find sufficient shelter in their enclosure while they are vulnerable, they will be easy pickings for larger crabs.

What do Blue Crabs eat?

Blue crabs have a diamond-shaped shell with a long spike extending to either side. They can be blueish grey to brownish green. Blue crabs like to eat other smaller crabs like the ghost crabs, but also marsh turtles and some species of marine snails . They also catch smaller marine crustaceans such as shrimp, barnacles, and even small lobsters. 9-11

what does a ghost crab eat

Important food items that blue crabs eat include:

They will also eat barnacles, insects, plankton, sea worms, and carrion when the need arises.

Females have orange and purple tips on their claws. They can be found in estuaries and lagoons and can tolerate both fresh- and saltwater conditions, but larvae need saltwater to grow.

Blue Crab diet

They are mainly active during the day and forage in shallow waters. They are active foragers that can move large distances. They probe the sand with their legs to find snails and clams burrowed in the sand.

Their ability to endure both saltwater and freshwater gives them a wider variety of habitats to forage in with a wider variety of food items compared to crabs that can only forage in either fresh or saltwater.

What do horseshoe crabs eat?

The horseshoe crab diet is made up of organisms that live in the soil or can be found on the soil surface.

what does a ghost crab eat

Their mouth is jawless and toothless and located between their legs. Sharp bristles on the insides of their legs grind food items before it enters their mouth.

Common food items of the horseshoe crab include:

  • Other crabs and shellfish

They will also eat small fish, plant material and seaweed.

Horseshoe crab diet

However, it is worth noticing that horseshoe crabs are not true crabs , but rather the last remaining species from an ancient group of creatures that have been around since before the dinosaurs.

Unlike true crabs, they have a long tail, twelve legs (instead of ten), and they lack antennae. They live offshore, buried under the soil, coming to shore periodically to lay their eggs. 4-7

They use their shovel-shaped shell and their legs to burrow into the soil, both for refuge and to forage. Each of their legs have a set of pincers, which they use to grab food items, crush shells, and bring food to their mouth.

Their ability to dig into the soil gives them the ability to forage on buried animals, while there are many other crab species that feed on similar food items, they usually need to find them above or close to the surface.

What do Fiddler Crabs eat?

The fiddler crab can be found on beaches and in lagoons, mudflats, mangroves, and swamps. 8 They prefer a mix of salt and freshwater and tolerate both to some extent but prefer brackish waters.

what does a ghost crab eat

Fiddler crabs feed on sandy beaches, mostly by scooping up sand in their claws and bringing it to their mouth. They sort through the sand for food particles with their mouthparts, leaving behind small balls of sand.

Common food items of fiddler crabs include:

  • Eggs of small marine creatures

They are opportunistic feeders and will eat carrion and, occasionally, predate on small crabs and mussels.  

Smaller claws are used for feeding and larger claws for fighting other males. They live in burrows in the sand on the beach.

In contrast to most other crabs, these crabs feed on land, instead of in the water. While they are adapted to spending time outside the water, they still need to wet their gills regularly to keep them moist and functional.

Beaches offer a unique transition between marine and terrestrial habitats and thus carrion and debris found on the beach could include elements from both habitats.

What do ghost crabs eat?

Ghost crabs are found on beaches, where they live in burrows. They are mostly active at night. Most ghost crabs have a pale color to blend in with their surroundings.

what does a ghost crab eat

Ghost crabs are active scavengers and hunters on the beach. As opportunistic feeders, they will eat anything they can find, but they seem to prefer animal-based over plant-based food sources. 12-14

Ghost crabs eat a wide range of food, including:

  • Crabs (including other ghost crabs)
  • Dune and sea plants

They will also eat plankton, marine worms, snails , debris, and larger prey, like sea turtle eggs and hatchlings, small lizards, and chicks of sea birds.

They have a box-shaped body and one claw that is bigger than the other, but not as big as in male fiddler crabs. Their long eye stalks give them a distinctive look.

Like the fiddler crabs, ghost crabs also forage on land. However, they forage at night, and they are active foragers and predators, in contrast to the fiddler crabs who mostly sift through sand for food particles.

However, when ghost crabs do participate in deposit feeding (filtration of sand) they can extract as much as 70% of the algae content of the sediment they ingest.

What do king crabs eat?

King crabs are the largest commercially important crab. They can grow up to 11 inches in body width and weigh 24 pounds.

what does a ghost crab eat

Their diet differs based on their location and on the presence of other competing predators in the area, showing that they are opportunistic feeders. 15  

The most important prey items of king crabs are:

  • brittle stars
  • sea urchins
  • other crabs
  • Algae and protists

King crabs are found in the polar regions of the world in shallow waters with rocks, boulders, or cobbles. They have eight legs, instead of ten, and are covered in sharp spines.

King crabs are large, fast-moving predators that will actively seek out their prey, either in groups or alone.

Even though they eat other crabs , cannibalism is rare in nature.

They will also eat plankton, microalgae, seaweed, fish, sponges, seagrass, and squid. When larger food items are scarce, they will scoop up sand to feed on smaller food items.

King Crab diet pie chart

Being one of the largest crab species, they consume larger prey items, compared to smaller crab species.

Their tendency to live and feed in large groups gives them the ability to take down large prey items such as large starfish.

What do snow crabs eat?

The snow crab is found in the polar regions, even further north than the king crab, preferring deep waters. They are bright red to brown with a round body and long legs.

what does a ghost crab eat

Adult males can reach 2 to 6.5 inches in body width and females 1.5 to 4 inches.

Snow crabs are slow-moving predators, preying mostly on sedentary animals and plant matter. 16-18

They will either catch their prey with their claws or scoop up sediment to their mouth and pick out food particles. Important food items include:

  • Other crabs
  • Brittle stars

They also eat plankton and debris. Cannibalism is common in snow crabs and is believed to shape the age structure of populations and the distribution patterns of individuals.

Snow crab diet

Different-sized snow crabs are found at different depths, possibly so that smaller crabs can avoid cannibalism by bigger crabs.   

Even though they are large, active predators, like the king crabs, they are slow-moving and mostly rely on sedentary prey.

What do green crabs eat?

Green crabs can be found in marine and estuarine habitats, including mud, sand and rocky areas in shallow waters.

what does a ghost crab eat

In rocky areas, green crabs also eat sea snails . They also feed on the seagrass and seaweed that they hide between.

Like the blue crab, they are active predators that hunt in shallow waters, but, unlike blue crabs, they cannot forage in fresh water. 10

Important food items in the diet of the green crab include:

  • Crabs (including their own species)

With their dark, mottled brown to green color they can easily blend in between aquatic vegetation or seaweed.

There is also a red color morph of the green crab that blends in better in deeper waters, where red light does not penetrate, and the crabs appear brown. Adult green crabs can reach 2 to 4 inches in body width.

What do mud crabs eat?

As the name suggests, mud crabs live in the mud of estuaries and mangroves.

what does a ghost crab eat

Mud crabs forage at night. They will eat anything they can find, especially stationary or slow-moving creatures and plant materials. 10

T he most common food items of mud crabs include:

  • Animal carcuses

They will also eat fish, plant material, debris, and carrion.

Some of them live in burrows. Depending on the species and location, mud crabs can be brown or black with hues of red, green or yellow. Adults can reach 6 to 11 inches in body width and weigh 3.5 to 6.5 pounds.

Living in estuaries and mangroves mean that they have different food types available than would be available in a marine environment. Like the ghost crabs, they are night-time foragers, therefore they can avoid competition with day-time foragers and feed on prey items that are active at night.

What do crabs eat when on land?

While most crabs are found either in saltwater or in freshwater, some crab species, like the fiddler crab and the ghost crab mentioned above, are adapted to living on land.

These adaptations enable them to find a wider variety of food sources such as insects, reptiles, and plant material.

What do crabs eat on the beach?

On the beach, crabs can sift through sand for small food particles, feed on carrion, look for snails , worms and other creatures that burrow into the sand, or pick barnacles and mussels from rocks.

what does a ghost crab eat

With the beach acting as an interface between land and sea, they can feed on both terrestrial and marine food sources.

For example, they can feed on both dune vegetation and kelp, insects and shellfish, and eggs of both terrestrial and marine animals.

What else do crabs eat? (Crab diet FAQs)

We have gone through the typical diets of a handful of common crabs above. However, I get many questions on specific items and whether they are included in the diets of our crustacean friends or not.

Below is a selection of common questions on food and my best efforts to answer whether crabs eat them or not. However, if you have read the article above, I am confident that you will already have a good idea of what items are included or not!

In fact, most animals that crabs can readily access, and that do not kill them, will be good sources of food for almost any crab. However, the accessibility of the food strongly depends on the type of crab hunting for the type of prey. More on this in the following!

Do crabs eat plankton?

Yes, several crabs have the ability to eat both zooplankton and phytoplankton.

Whereas zooplankton is basically microscopic animals and protists, phytoplankton consists mainly of microalgae (single-celled plants), but is often loosely defined as all microorganisms that obtain their energy from the sun, which would include cyanobacteria and Euglena species .

The prevalence of each type of plankton in their diet depends on the environment in which they live, and they usually don’t distinguish or have a preference between them. Crabs eat plankton either by filtering the water or the sand and other sediments for microscopic particles.

Crabs that filter the water for plankton are called filter-feeders while those that filter sand or sediment are called deposit-feeders. Some of these have specialized gills that are used for feeding as well as breathing !

An example of a filter-feeding crab is the porcelain crab. They are called porcelain crabs due to their fragile nature and they tend to lose limbs. Luckily, crabs can regenerate most of their limbs again .

Porcelain crabs have specialized appendices on their arms that look like an antenna but rather than catching radio signals, they catch all sorts of planktonic microorganisms such as Euglena and algae.

This type of filter-feeding with suspended appendages is also called “suspension-feeding”.

Hermit crabs, such as the common marine hermit crab ( Pagurus bernhardus ), can also filter feed. Although hermit crabs lack the specialized organs of the porcelain crabs, they can use their front legs to generate a current of water into their mouth from which they eat the zoo and phyto plankton present in the water.

what does a ghost crab eat

Examples of deposit-feeders are fiddler crabs, ghost crabs, Semaphore Crab, and Sand Bubbler Crabs. These crabs “ingest” the sand to filter out plankton particles, bacteria, and leftovers of dead animals, and plants.

Do crabs eat seaweed?

Yes, most crab species eat seaweed as can be seen from the stomach contents studies presented at the beginning of this article.

They will eat different types of seaweed, from giant kelps to small sea lettuce.  

Crabs use their pincers to cut off pieces of seaweed or to pluck seaweed from the substrate and bring it to their mouth.

However, most crab species seem to prefer animal-based food over seaweed, since animal-based food is higher in nutrients – especially protein, which often constitutes up to 30% of a crab’s diet.

 Seaweed, however, often serves as an abundant and easily accessible food source, especially during hard times when other food sources might not be available.

Do crabs eat algae?

Yes, most crabs can eat algae in one form or the other.

Crabs can eat either microscopic algae such as phytoplankton or macroscopic algae such as seaweed.

As described in the two sections above, algae is a common food source for crabs and they will either filter it from sand or water or eat macroscopic algae directly using their claws and mouthparts.

Some species do also scrape off and eat densely packed layers of sediment from rocks and other objects in the sea where algae grow along with bacteria.

Do crabs eat shrimp?

Yes they do. Because crabs are omnivorous and sometimes cannibals they do not hesitate to eat fellow crustaceans – including shrimp.

Crabs and shrimp reside together at the bottom of the sea where they both feed on decaying plant and animal matter.  

And because they reside in the same niche, they will often encounter the remains of each other’s decaying bodies and crabs are not picky when it comes to dead animal matter in their diet!

However, living shrimp are relatively small and oftentimes too fast for most crabs to catch.

Do crabs eat amphipods?

Most crabs will eat dead amphipods as they are an excellent source of protein and reside in the same environment. 

Amphipods are crustaceans ranging from about 0.04 inches to more than 10 inches in size. They are scavengers like crabs, and often reside in the ocean floor with crabs and other crustaceans.

While amphipods are often fast for most crabs to catch when alive, many types of fish, including Mandarin fish, Clownfish and Pipefish, are fast enough to hunt and eat smaller amphipods in aquariums.

However, smaller crab species like the hermit crabs are known to be quite proficient at catching and feeding on amphipods. Therefore, hermit crabs may also be used to get rid of unwanted amphipods in fish tanks.

Do crabs eat crayfish?

Rarely, but mostly because they are hard to catch.

While crabs and crayfish are scavengers eating mostly dead animals, they can both be aggressive if feeling threatened and both do sometimes attack other crustaceans.

There are many examples of crabs eating crayfish and vice versa. It is often the bigger of the two that initiates the aggression and wins the fight.

When crabs and crayfish fight the crab tends to win because a larger proportion of a crab’s body is covered by hard shell and the tail of the crayfish is exposed to the claws of the crabs.

However, crayfish and lobsters have a strong flexible tail that allow them to swim away from encounters fast, often saving them from being eaten by crabs.  

Do crabs eat starfish?

Yes! Especially the bigger crab species like the King Crab.

While you might think that starfish are slow movers and easy prey for crabs, it is not common for most crabs to eat starfish (or sea stars) in nature.

Although a starving crab may be encouraged to attack and eat living starfish, crabs usually prefer to eat them after they have died.

Living starfish are usually consumed by larger crabs such as the Snow Crab and King Crab and starfish constitute around 15% of snow crabs diet (see section on snow crab food preferences above).

 They are usually eaten to a lesser extent by King Crabs and mostly at 16-50 meter sea depths and rarely deeper than 80 meters.

But what about the other way around?

Starfish may actually be quite aggressive towards crabs and are known to attach and devour living crabs via coordinated attacks in large numbers.

For example, the North Pacific Starfish has been observed to overwhelm fairly large spider crabs and eat them during moulting season.  

Do crabs eat sea urchins?

Some crabs, like the king crab, eat sea urchins, but it requires a certain strength to open their shell.

Sea urchins are challenging to eat because most of their body is covered in a hard spiky shell.

However, crabs also carry hard exoskeletons, so crabs do have the ability to withstand the spikes of sea urchins.

Furthermore, the claws of larger crabs are able to break the shell of sea urchins to access and eat their soft tissue.

A good example is the King Crab that is fairly capable of consuming sea urchins and does so almost all water depths. King Crabs are strong and can easily crush the shell of sea urchins with their pinchers.

King crabs have been documented to eat sea urchins at sea depths as deep as 300 meters.

Do crabs eat jellyfish?

Yes, but since crabs live on the bottom of the sea they do often not easily come into contact with jellyfish that swim in the open sea. However, they will be able to reach dying or stranded jellyfish and they will also eat swimming jellyfish when possible.

The early life stages of jellyfish do take place attached to the sea floor where they are easy prey for the crabs they may encounter.

Crabs may also encounter jellyfish that have died and washed up on the beach. Fiddler crabs and ghost crabs would be happy to feast on such a catch.  

In these cares some crabs might be opportunistic feeders and eat the jellyfish. The stinging cells of jellyfish are unlikely to penetrate the hard shell and mouth pieces of crabs and do not bother them.

Do crabs eat fruit?

Yes, some crabs, like the coconut crab and some hermit crabs, do indeed eat fruit!

It may seem surprising, but there are many land crabs that eat fruit pulp.

Depending on the crabs size it can grab hold of and drag away large fruits such as Mangoes.

The coconut crab is gigantic (in fact the largest terrestrial crab alive!) and has evolved to be able to climb palm trees and break into coconuts to eat them.

By moving fruits that contain seeds, crabs can contribute to seed dispersal which helps plants establish in new areas.

See the video below for a brief introduction to the coconut crab:

Do crabs eat sand?

No, they do not eat the sand, but they filter it for food.

Some crabs do indeed appear to eat sand. But in fact, they are filtering the sand (so called deposit-feeding) and eating the contained algae, cyanobacteria , small invertebrates and/or tiny particles of dead animals.

Some crabs, like the mole crab, ghost crab, and fiddler crab frequently participate in filter-feeding and can extract up to 70% of plant and nutrient matter from the filtered sand. 

If you buy sand or rocks for you aquarium however, I would recommend you to sanitize it for microorganisms first. The ecosystem of your aquarium will establish itself and your crabs will soon be able to feed on the algae, protists and death animal matter that accumulate in the sand.

Do crabs eat turtles?

Crabs generally leave adult turtles alone but are a big problem for small sea turtles.

Baby turtles, as cruel as it may be, are often eaten by crabs when they emerge from their nests on the beach or when they are still in their eggs.

Because crabs can run much faster on the beach than baby sea turtles, they may catch them before they can reach the sea to swim off.

The crabs eat the soft parts and leave the rest. Some crabs are known to eat the flesh of dead animals, including land- and sea turtles.

Do crabs eat anemones?

Dead anemones are easy prey for most crabs.

However, live anemones have protective stinging cells as jellyfish do. While these will not always penetrate the hard shell and mouthparts of crabs, crabs may feed on them opportunistically.

But rather than eating anemones, some crabs use them to their advantage in other ways.

Crabs like the Pom Pom crab do not eat anemones and have instead developed a symbiotic relationship with them.

This beautiful crab is very small and therefore vulnerable to being eaten by big fish.

As a defence mechanism, the Pom Pom crab constantly holds two small anemones in its claws, waving them around like a cheerleader.

The anemones are used by the crab to chase predators away by stinging them and in turn, they get the benefit of eating part of the crab’s food.

Do crabs eat squid and octopi?

If the squid is dead – yes! But a large squid or octopus is a challenge for most crabs.

The Cephalopoda is a group of marine mollusks that includes cuttlefish, squid, nautilus, and snails , is characterized by symmetrical bodies with tentacles protruding from the body.

Octopuses are soft cephalopods, which do not have an outer shell and include the giant Pacific octopus.

Many larger squid and octopuses actually love to feed on crabs ! Especially the giant pacific octopus loves to attack and eat marine crabs.

Do crabs eat worms?

Yes, most crabs eat many types of marine worms especially bristle worms like sandworm, clamworm, and lugworm.

Worms, especially the marine members of the Polychaeta class of worms, are an important food source for many crabs.

However, some crabs eat more worms than others and worms.

Whereas worms are seldom found in the diet of the Blue Crab, they make up around 10% of the Snow Crab, King Crab and Horseshoe Crabs diets.

Do crabs eat insects?

Yes, but mostly those that feed on land.

Insects are more or less strictly land animals and do not live underwater where most crabs reside.

Those crabs, like the mole crab, fiddler and ghost crabs that filter through sand to find food, do however, ingest quite a substantial amount of insects.

Also, dead insects may drop to the bottom of lakes and the sea where crabs will be able reach and ingest them.

Do crabs eat flies?

Flies are not readily accessible to crabs as flies are only found on land. Dead flies however may be eaten by crabs if they fall into the water.

Flies may also be present in the sand that is filtered by deposit-feeding crabs such as the fiddler or ghost crabs.

Do crabs eat spiders?

The short answer is no.

Because spiders are insects that live strictly on land, they are unlikely to make up a substantial part of any crabs diet.

Although rare, small spiders or their eggs may be filtered from sand by filter-feeding crabs.

Do crabs eat geckos?

Because geckos are not water animals, few marine crabs would have easy access to geckos.

If land crabs are fast enough they might be able to catch a gecko, but it is unlikely as geckos are faster than crabs. Therefore it is not likely to be part of most crab diets. However, dead lizards are known to be eaten by many crabs.

However, some geckos will accidentally fall into the water and most geckos are able to swim – and some can even run on the water surface !  

But because geckos swim significantly slower than they can run on land, there will be a chance that they will be caught by a hungry crab or another water predatory animal.

Do crabs eat frogs?

Crabs that live in seawater are unlikely to encounter frogs because these can only survive in freshwater.

However, the crabs that live in freshwater could catch frogs and eat them, but they need to be fast.

They are much more likely to feed on dead frogs, tadpoles or frogspawn .

Do crabs eat seagulls?

If a terrestrial crab encounters a dead seagull , then yes!

There are even examples of the large coconut crab attacking and overwhelming living sea birds on land .

What do crabs eat in a fish tank?

They will eat whatever is present such as fish food, algae, cyanobacteria and dead animals. Most crabs do a good job at cleaning out your tank.

They eat mostly the same as they would eat in the wild. All the items previously described in this post can be good options for feeding your pet crab.

Many of the food items eaten by crabs in captivity will overlap with those listed for the different crabs described previously in this article. So be carefull if you plan to keep crabs and e.g. snails or crayfish together.

However, you can also buy designated crab food items suited for crabs kept in fish tanks in your lokal pet store.

Crabs are diverse and fascinating creatures. Their diet is variable and adaptable, shaped by both food availability and nutrient requirements.

There is no simple answer to the question “What do crabs eat?” because crabs include vastly different species living in different environments.

However, understanding their natural diet helps us understand the nutritional needs of crabs in captivity and elucidates the vital role they play in the ecosystem.
