An oligochaete is a member of the class Oligochaete, which includes annelids (segmented worms), characterized by long, naked bodies bearing a few bristles (chaetae) on each segment. Earthworms are the best-known oligochaetes, but many are freshwater worms as small as 1 mm (0.025 inch) long. Giant Australian earthworms grow up to several meters long.
