Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton.They range in length from less than 0.5 mm (0.02 in) up to 2 to 3 metres (6.6 to 9.8 ft) in the 'giant' species such as the giant Gippsland earthworm (Megascolides australis) and the Mekong worm (Amynthas mekongianus).
The other subspecies (Ch. l. limnaei) attaches itself externally to the body of snails or to the inside of their shell (Lymnaea, Physa, Ancylus, Australorbis and many other genera [3]) and can freely move (so-called commensal ectosymbiosis). It consumes various tiny organisms that it manages to suck in from its vantage point on its host.
