It is currently known from 12 locations in the wet zone including Beraliya, Dombagaskandha, Madakada, Gilimale, Hiyare, Kottawa, Kanneliya, Weddagala, Nakiyadeniya, Pahiyangala and Boralugoda. It is recorded from a wide range of altitudes. Due to its restricted range and the threats to its habitat Lepidocephalichthys jonklaasi, is listed as an Endangered species. The species has already begun to disappear from some of the sites mentioned above due to destruction and fragmentation of its habitat and many other threats that are operating on the species. == Morphology == Members of the genus Lepidocephalichthys have a sharp, erectile spine on their cheeks. In some species the spine is sharp enough to puncture easily one’s hand during handing of the live fish. However, it is not venomous or harmful. These fish have an ancillary respiratory mechanism where they swallow air, which is then used to oxygenate the blood that passes through the walls of the intestines. Unlike the case of the channids and anabantids, the air is not expelled through the mouth or gills, but via the anus. This enables them to survive in very poorly oxygenated water although in Sri Lanka, by and large, they occur in habitats that do not require this facility and are not generally considered as “air breathers”. The loaches are small, eel-like or worm-like fish, often attractively colored. They have (often rudimentary) cycloid scales and three pairs of barbells. Mature males in many species have highly modified pectoral fins (Roberts, 1989). Little is known about the breeding habits of the members of this family cobitidae and only a few species have been bred in captivity to date. 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「Lepidocephalichthys jonklaasi」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
