Crabs are (usually) marine crustaceans. They have ten legs (counting specialized ones, e.g., claws or flattened pair of hind ones for swimming). Their body is generally broad and flattened; their eyes on short stalks, with the abdomen small and folded under the thorax. Commonly they have a hardened shell. The term crab is also used to describe other creatures with superficial similarities to true crabs, e.g., crustaceans like the hermit crab or horseshoe crab. There is also a parasite called a crab louse; body lice are informally referred to as crabs.
