Chilopoda
Chilopoda (centipedes; phylum Arthropoda, subphylum Atelocerata) A class of uniramous arthropods that have segmented bodies with one pair of legs to each segment. Some centipedes are adapted to burrowing in soil but most run on the surface. All are believed to be predators. The head bears long antennae and beneath the mouth-parts there is a large pair of claws (maxillipeds, forming part of the first body segment) that inject poison. Below the
mandibles a pair of
maxillae forms a functional lip, overlain by a second pair of maxillae. The name, Chilopoda, is derived from the Greek
cheilos, lip, and
pod-, foot. There are about 3000 species, found world-wide, and grouped in two subclasses (Epimorpha and Anamorpha) and four principal orders: Geophilomorpha; Scolopendromorpha; Lithobiomorpha; and Scutigeromorpha.
