Each segment, except the one behind the head and the last two in the body, bears a pair of jointed legs. Appendages of the first body segment are modified to form poison claws. The last pair of legs is longer than the others and serve a sensory function. There are a pair of antennae, a pair of mandibles, one or two pairs of maxillae, and a pair of eyes on the dorsal side of the head. They are carnivores and feed on cockroaches, and other insects and earthworms. They kill their prey with their poison claws and chew it with their mandibles. There are 3,000 species worldwide.
