Pauropoda
Pauropods are small, pale, centipede-like arthropods. They form the order Pauropodina, belonging to the monotypic class Pauropoda. About 500 species in four families are found worldwide, living in soil and leaf mould. They look rather like centipedes, but are probably the sister group to millipedes. The name is derived from the Greek roots ' "few" and ' "foot". ==Anatomy and ecology==
Pauropods are soft, cylindrical animals with bodies long.〔 The first instar has three pairs of legs, but that number increases with each moult so that adult species may have nine to eleven pairs of legs. They have neither eyes nor hearts. The body segments have ventral tracheal/spiracular pouches forming apodemes similar to those in millipedes and Symphyla, although the trachea usually connected to these structures are absent in most species. The antennae are branching, which is distinctive for the group. Pauropods live in the soil, usually at densities of less than 100 per square metre (9/sq ft).〔
