Class ChilopodaAnatomy
centipedes have a segmented body and paired, jointed appendages on most segments millipedes have a cylindrical body with two pairs of legs on most segments, while centipedes are dorso-ventrally flattened and have only one pair of legs on most segments head of a centipede has a pair of jointed antennae centipedes are covered by a hard exoskeleton, made out of protein and a tough polysaccharide called chitin Reproduction System Male centipedes spin a small web onto which they deposit a spermatophore for the female to take up. Sometimes this involves a courtship dance, but sometimes the males just leave the spermatophore for the females to find. Lithobiomorpha and Scutigeromorpha orders lay their eggs singly in holes in the soil |
