Enchytraeidae
Enchytraeidae is a family of microdrile oligochaetes. They resemble small earthworms and include both terrestrial species known as potworms that live in highly organic terrestrial environments, as well as some that are marine. The peculiar genus ''Mesenchytraeus'' is known as "ice worms", as they live in glaciers and will die if exposed to temperatures a few degrees above freezing. Apart from these, the best-known species is probably the Grindal Worm (''Enchytraeus buchholzi''), which is commercially bred as aquarium fish food. Selected genera Enchytraeidae genera include:WoRMS (2010) * ''Achaeta'' Vejdovský, 1878 * '' Archienchytraeus'' Eisen, 1878 ('' nomen dubium'') * ''Cernosvitoviella'' Nielsen & Christensen, 1959 * '' Christensenidrilus'' Dózsa-Farkas & Convey, 1998 (= ''Christensenia'' Dózsa-Farkas & Convey, 1997 (''non'' Brinck 1945: preoccupied)) * ''Cognettia'' Nielsen & Christensen, 1959 * '' Enchytraeina'' Bülow, 1957 * ''Enchytraeus'' * '' Epitelphusa'' Drago, ...

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 ...
