What is Sand Crab?
A sand crab, also known as a mole crab, blue crab, or ghost crab, is a tiny crab that belongs to the family Hippidae of the species Emerita. As the name implies, you can see this crustacean on sandy beaches. It is a favorite bait in fishing and a typical food for birds.
This tiny crab, measuring only up to two inches, moves backward and quickly burrows itself in the wet sand for protection. However, since this small crab lives in the area of the ocean with the most algae, it tends to have domoic acid, mainly when found in areas with specific algae that produce it.
Unlike other larger crab species, they lack functional legs to help them maneuver walking in deep waters. Thus, they stay in the sand area and wait for the water to roll back to the sea to catch some plankton using their antennae. Smaller crabs feed on worms, algae, and mollusks, while larger sand crabs feed on carcasses and baby turtles.
Can You Eat Sand Crab?
Yes, you can eat sand crabs, especially the ones you see in clean beach sand and areas with little algae. However, you should never eat raw sand crab, as it may contain toxins, heavy metals, and bacteria that impose risks to human health.

Are Sand Crabs Healthy?

However, sand crabs are also potential carriers of toxins they may get from the water or sandy beaches.
To be sure, avoid catching sand crabs from beaches near sewage systems, beaches with algae, and generally dirty beaches. You should never eat raw sand crabs. Clean sand crabs thoroughly with running water before cooking them to avoid health issues.
How Do You Catch Sand Crabs?
The first thing to consider is their size if you’re at the beach and want to get sand crabs or mole crabs. Female sand crabs are often larger than males, making them a better option for consumption.
When planning to catch sand crabs, you should have a rake or a net to help make your job easier. It’s also wise to consider the tide since high tide means a lesser chance of catching sand crabs. However, if you don’t have the time, you can purchase sand crabs in local supermarkets near beaches or find locals who catch and sell them at a lower price.

Sand crab meat is tender and has a buttery taste. Still, you can enhance it by adding a seafood boil seasoning mix and vegetables like corn, cauliflower, carrots, potatoes, and onions.
