''Anurida maritima'' is a cosmopolitan collembolan of the intertidal zone. It is often found in aggregations of up to several hundred on the surface of rock-pools. ==Description== ''A. maritima'' is a wingless animal, typically up to 3 mm long, and dark slaty blue in colour. Its body is roundish, expanding slightly towards the rear. The head bears a pair of eyes and a single pair of antennae, the thorax comprises three body segments, each of which bears one pair of legs, while the abdomen comprises six segments.〔 The entire body is covered with white hydrophobic hairs which allow the animal to stay above the surface of the water on which it spends much of its life. Unlike other springtails, ''A. maritima'' cannot leap, since its furcula is vestigial. This is apparently because when other springtails are placed upon water, surface tension unfolds their furcula and renders them unable to jump, so it has probably been lost by disuse.〔
