They are true masters of camouflage, with their coloration helping them blend seamlessly into their beach environments upon which they reside.
Here is a picture of a crab, so you know what you are looking for. This is a male – notice the larger claw:
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.
- Small and rounded
- Live in the swash zone
- No visible legs
- Larger and agile
- Live in burrows
- Possess visible legs including four pairs of walking legs
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

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?

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.
