''Acestridium'' is a genus of freshwater fish in the family Loricariidae of order Siluriformes. The type species is ''Acestridium discus''. The genus name is derived from latinised Greek 'agkistron' meaning hook. ''Acestridium'' species are native to small streams of the Amazon region of Brazil, Venezuela, and Colombia.〔 Species of this genus are found in litter banks. Members of this genus typically are long and thin, or 'twiglike' and superficially resemble the genus ''Farlowella'' of the same family. Adult length is 5–7 cm and each species shows adaptation for camouflage in the water margins - bright green leaf like in ''Acestridium dichromum'' and varigated brown in other species. == Species == There are currently seven recognized species in this genus:〔 * ''Acestridium colombiense'' Retzer, 2005 * ''Acestridium dichromum'' Retzer, Nico & Provenzano, 1999 * ''Acestridium discus'' Haseman, 1911 * ''Acestridium gymnogaster'' Reis & Lehmann A., 2009 * ''Acestridium martini'' Retzer, Nico & Provenzano, 1999 * ''Acestridium scutatum'' Reis & Lehmann A., 2009 * ''Acestridium triplax'' Rodriguez & Reis, 2007 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「Acestridium」の詳細全文を読む スポンサード リンク
