The Enchytraeidae are a microdrile oligochaete family. 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, 1887 * ''Fridericia'' Michaelsen, 1889 * ''Grania'' * ''Hemifridericia'' Nielsen & Christensen, 1949 * ''Henlea'' Michaelsen, 1889 (= ''Henleanella'') * ''Lumbricillus'' Ørsted, 1844 (= ''Enchytraeoides, Pachydrilus'') * ''Marionina'' Michaelsen in Pfeffer, 1890 (= ''Marionia'' Michaelsen, 1889 (''non'' Vayssière, 1877: preoccupied), ''Michaelsena, Parenchytraeus'') * ''Mesenchytraeus'' – ice worms * ''Neoenchytraeus'' Eisen, 1878 * ''Randidrilus'' Coates & Erséus, 1985 * ''Stephensoniella'' Cernosvitov, 1934 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Enchytraeidae」の詳細全文を読む スポンサード リンク
