''Brachionichthys'' was, until recently, the only genus in the family Brachionichthyidae (commonly known as handfishes), but presently five genera are placed in this family of anglerfishes.〔Last, P.R.; Gledhill, D.C. 2009: A revision of the Australian handfishes (Lophiiformes: Brachionichthyidae), with descriptions of three new genera and nine new species. ''Zootaxa'', 2252: 1-77. (Abstract and excerpt ) (PDF )〕 They use their pectoral fins to walk about on the sea floor. These highly modified fins have the appearance of hands, hence their scientific name, from Latin ''bracchium'' meaning "arm" and Greek ''ichthys'' meaning "fish". The prehistoric species ''Histiontophorus bassani'', from the Lutetian of Monte Bolca, is now considered to be a handfish, sometimes even being included in ''Brachionichthys''. ==Species== The currently recognized species in this genus are: * ''Brachionichthys australis'' Last, Gledhill & Holmes, 2007 (Australian spotted handfish) * ''Brachionichthys hirsutus'' Lacépède, 1804 (Spotted handfish) 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「Brachionichthys」の詳細全文を読む スポンサード リンク
