Sisoridae is a family of catfishes. These Asian catfishes live in fast-moving waters and often have adaptations that allow them to adhere to objects in their habitats. The family includes about 235 species. ==Taxonomy== The family Sisoridae is recognized as a natural, monophyletic group based on morphological and molecular evidence.〔 It is divided into two subfamilies, Sisorinae and Glyptosterninae (glyptosternoids). The Sisorinae contain the five genera ''Bagarius'', ''Gagata'', ''Gogangra'', ''Nangra'', and ''Sisor''. The Glyptosterninae contain three tribes. Glyptothoracini contains only the genus ''Glyptothorax'' and Pseudecheneidina contains only the genus ''Pseudecheneis''. The remaining genera, ''Euchiloglanis'', ''Exostoma'', ''Glaridoglanis'', ''Glyptosternon'', ''Myersglanis'', ''Oreoglanis'', ''Parachiloglanis'', ''Pareuchiloglanis'', and ''Pseudexostoma'', are contained in the tribe Glyptosternina.〔 The monophyly of the entire family and the tribe Glyptosterninae are well supported by osteological morphology and molecular data.〔 In the genera ''Glyptothorax'' (tribe Glyptothoracini) and ''Pseudecheneis'' (tribe Pseudecheneidina), the species have thoracic adhesive apparatuses to attach to objects in the stream bed; in ''Glyptothorax'', grooves of this apparatus run parallel or oblique to the axis of the body, while in ''Pseudecheneis'' grooves run transverse to the axis of the body. The thoracic adhesive apparatus is not present in the other sisorid genera. The paired fins may be plaited to form an adhesive apparatus in ''Pseudecheneis'', glyptosternoids, and variably in ''Glyptothorax''. Thus, glyptosternoids lack a thoracic adhesive apparatus, but do have plaited paired fins, and members of the subfamily Sisorinae lack either a thoracic adhesive apparatus or plaited paired fins.〔 The monophyly of certain glyptosternoid genera is doubtful. The paraphyly of ''Pareuchiloglanis'', ''Oreoglanis'', and ''Pseudexostoma'' (with the possible inclusion of ''Myersglanis'' and ''Parachiloglanis'') has been demonstrated and a rediagnosis of glyptosternine genera is needed. Evidence from a 2007 molecular analysis supports polyphyly of ''Pareuchiloglanis''. ''Glaridoglanis'' might be a basal member of the tribe Glyptosternina. ''Pseudecheneis'' may be placed in the tribe Glyptosternina, but its sister-group relationship between it and the monophyletic glyptosternoids cannot be rejected. It has been proposed to move the genera of Erethistidae into Sisoridae. 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「Sisoridae」の詳細全文を読む スポンサード リンク
