Chelipeds are the large claws that many crabs have on two of their legs. They use these chelipeds for feeding and defense. The number of chelipeds a crab has can be a clue to how many legs it has in total.
For example, hermit crabs have one large claw and three small claws on each of their first two pairs of legs. This means they have a total of eight legs.
