簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 2; 背的軟條 (總數) : 7; 臀棘: 0; 臀鰭軟條: 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).
通常生存於浮游植物堆的流動的水,湖與水中植物, 稀有的在岸邊的植叢中。 吃在泥,殘礫,昆蟲上的底部, 特別地寶刀魚仔魚與軟體動物。 懷孕的魚被記錄全年度具有一個高峰乾季時.(參考文獻 28714)
