Crabs are in the class crustaceans, which are in the phylum arthropoda. All arthropods have an exoskeleton, which for crabs, helps protect them from predators, support them when not in water, allows muscles to be attached to the shell, and can keep them from drying out when not in water. They have "claws" that help them manipulate their food. They also have 2 pairs of antennae for sensing.
