''Steatocranus'' is a small genus of rheophilic cichlids mostly native to the Congo River Basin in DR Congo/Congo Brazzaville, although one species, ''S. irvinei'', is restricted to the Volta River in Ghana and will likely be removed from this genus at a future date. There are also at least 10 undescribed species awaiting description. The fish in this genus all have relatively reduced swim bladder function. The name ''Steatocranus'' refers to the fatty deposit on the forehead of most species. Two species, ''S. casuarius'' (also known as the Buffalohead Cichlid) and ''S. tinanti'' are relatively common in the aquarium trade. As for other cichlids brood care is highly developed and both sexes are involved in raising the young. All ''Steatocranus'' species are secretive cave spawners and form monogamous pairs for breeding. The female is more actively involved in fry raising, while the male is primarily concerned with territorial defence. ==Species== There are currently nine recognized species in this genus: * ''Steatocranus bleheri'' M. K. Meyer, 1993 * ''Steatocranus casuarius'' Poll, 1939 (Lionhead cichlid) * ''Steatocranus gibbiceps'' Boulenger, 1899 * ''Steatocranus glaber'' T. R. Roberts & D. J. Stewart, 1976 * ''Steatocranus irvinei'' (Trewavas, 1943) * ''Steatocranus mpozoensis'' T. R. Roberts & D. J. Stewart, 1976 * ''Steatocranus rouxi'' (Pellegrin, 1928) * ''Steatocranus tinanti'' (Poll, 1939) * ''Steatocranus ubanguiensis'' T. R. Roberts & D. J. Stewart, 1976 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「Steatocranus」の詳細全文を読む スポンサード リンク
