Centipede vs. Millipede

Centipedes (from the New Latin prefix centi-, "hundred", and the Latin word pes, pedis, "foot") are predatory arthropods belonging to the class Chilopoda (Ancient Greek χεῖλος, kheilos, lip, and New Latin suffix -poda, "foot", describing the forcipules) of the subphylum Myriapoda, an arthropod group which also includes millipedes and other multi-legged creatures. Centipedes are elongated metameric creatures with one pair of legs per body segment.
