简单描述
检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 2; 背的软条 (总数) : 7; 臀棘: 0; 臀鳍软条: 6 - 8. Diagnosis: head broad (width at least 2/3 of length); snout length less than 0.9 times head width; hind margin of adipose fin nearly straight; premaxillary dentition forming (in adults) 2 well separated, kidney-shaped plates; maxillary barbels never black and reaching at least to hind margin of eye; 8-11 (usually 9 or 10) gill rakers on lower limb of first gill arch; palatine membrane bilobed (with a large and a smaller lobe); dorsal margin of cleithral process broad and flat (visible only in adults)(Ref. 57126).
Commonly occurs in running water, lakes and submerged vegetation in the Sudd, rare in fringing vegetation. Feeds on the bottom on mud, debris, insects, notably chironomid larvae and mollusks. Gravid fish are recorded throughout the year with a peak in the dry season (Ref. 28714).
通常生存于浮游植物堆的流动的水，湖与水中植物, 稀有的在岸边的植丛中。 吃在泥，残砾，昆虫上的底部, 特别地宝刀鱼仔鱼与软件动物。 怀孕的鱼被记录全年度具有一个高峰乾季时.(参考文献 28714)
