The front two legs are modified into claws, called chelipeds, which are used for defense, feeding, and communication. In summary, while crabs and animals that look like crabs with 8 legs share some similarities, they have distinct differences in their body shape, appendages, and behavior that make them easily distinguishable. Their legs are also longer and more spindly than those of crabs, and they are often used for walking and clinging to surfaces.

They also have a distinct 'tail' or 'abdomen' section, which is folded under their body and is used for swimming, balance, and reproduction.Īnimals that look like crabs with 8 legs, on the other hand, have longer, narrower bodies and their claws are typically smaller and less developed.
