Crabs

Crabs are hard-shelled arthropods that walk along the seabed or up onto seaweeds with their jointed legs. Two major groups of crabs are the true crabs, including the Dungeness crab eaten in seafood restaurants, and the lithode crabs, which include box and king crabs. True crabs have four pairs of walking legs, and are also smooth looking. Lithode crabs have three pairs of walking legs, and are more dramatic looking.
