Centipedes (Class Chilopoda) are fast-moving venomous, predatory, terrestrial arthropods that have long bodies and many jointed legs. Chiefly nocturnal, centipedes are found primarily in tropical climates but are also widely distributed in temperate zones. Some species are highly venomous but human deaths are very rare (

Like the millipedes (which, unlike centipedes, are not venomous), centipedes are highly segmented (15 to 173 segments), but with only one pair of walking legs per segment. Centipedes are dorso-ventrally flattened, and are among the fastest and most agile of non-flying arthropod predators.
The head of a centipede has a pair of antennae, jaw-like mandibles, and other mouthparts. The most anterior trunk segment of a centipede has a pair of venomous claws (called maxillipeds) that are used for both defense and for capturing and paralyzing prey. Despite their name, which stems from the Latin words centum (meaning 'hundred') and pes, pedis (meaning 'foot'), they normally have around half that number of legs, though it is possible to find centipedes with over 200 legs.
The house centipede (Scutigera coleoptrata) is a fast-moving carnivore that feeds on insects such as cockroaches, house flies, and other small house pests, and is thus domestically beneficial in nature. Though generally harmless to humans, its alarming appearance and painful bite (like a bee sting) result in its extermination from residences (

I made a
photo album out of this freaken français:Chilopoda
Article de Wikipedia, l'encyclopedie libre Les chilopodes (Chilopoda) sont une classe d'arthropodes myriapodes. Chacun des nombreux segments porte une paire de pattes sauf le premier dont la paire d'appendices est transformée en paire de crochets à venin appelés forcipules et les deux derniers. Les chilopodes sont prédateurs d'autres arthropodes ou de vers. Ils sont tous terrestres mais ont besoin d'un milieu humide car leur cuticule ne possède pas de couche de cire leur permettant de résiter à la sècheresse, ils sont aussi lucifuges (ils fuient la lumière). La morsure des plus grandes espèces est douloureuse pour un homme adulte et peut parfois être dangereuse pour un enfant(
