What Are Crabs?

Crabs are marine-dwelling crustaceans. Besides crabs, crustaceans include creatures such as lobsters and shrimp.

Crabs are called decapods. Deca means ten and pod means foot. Crabs have 10 feet - or legs. Two of those legs are the crab's characteristic large front claws, or pinchers. Crabs use these claws for cutting, crushing, and grasping.

Crabs can be amusing to watch with their funny way of walking sideways. They walk this way because their legs are attached to the sides of their bodies. And, their joints bend outward, unlike our knees, which bend forward.

They are also easily recognized by their eyes. Their compound eyes, which are on stalks that grow from the top of their bodies like snails, help them to see better in low light conditions and spot their prey. 

Crabs are omnivores, which means they eat both plants and animals. Their diet consists of foods such as algae, worms, sponges, and other crabs. Crabs are also eaten by humans. Some crabs, such as hermit crabs, are kept as pets.

There are many different species of crabs found in all the Earth's oceans, in freshwater, and on land. The smallest is the pea crab, named because it's only about the size of a pea. The largest is the Japanese spider crab, which can be as large as 12-13 feet from claw tip to claw tip.
