Annelids
The annelids (Annelida , from Latin ', "little ring"), also known as the segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments. The Annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of polychae ...

Criodrilidae
The family Criodrilidae is represented by genus ''Criodrilus'' comprising limicolous (mud-dwelling) and/or aquatic earthworms endemic to the Palaearctic currently known only from Europe and Japan, respectively. Only three or four species are described, and the type, ''Criodrilus lacuum'', has been introduced into North and South Americas, and is found rarely in plant pots or paddy fields. The Criodrilidae are characterised by holoic nephridia absent from anterior segments (cf. ''Pontodrilus''), a simple gut with no gizzard and no typhlosole. They are true earthworms, having a complex vascular system with capillaries, the male pores (on 15 or 13) behind the female pores (on 14) and a multicelled clitellum. They were at one time placed in the earthworm families Glossoscolecidae or Almidae, but at present are considered to constitute their own family. Criodrilidae species (criodrilids) are found in mud next to lakes and waterways (cf. North American ''Sparganophilus''). They fee ...
