簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 14-20; 臀棘 0; 臀鰭軟條: 24 - 30. LS/D 2.9-4.3;LS/PD 10.8-15.5. Pectoral fin longer or at least as long as head. Globular swelling on chin reduced. Base of dorsal fin 0.51-0.78 x of the anal fin base. Generally uniformly silver color but may sometimes be irregularly mottled on the sides.
LS/D 2.9-4.3;LS/PD 10.8-15.5. 胸鰭更長的或至少長達頭部。 在下巴上的球狀的膨脹縮小的。 背鰭基底 0.51-0.78 倍於臀鰭基底。 通常均勻銀色的顏色有時但是可能是有不規則斑點側邊上。
Distribution area is mainly continental and it is rarely found in the lower courses of basins (Ref. 81274). Inhabits fringing vegetation in the Sudd and migrates onto the floodplain to spawn (Ref. 28714). Bottom feeding insectivore (Ref. 28714). It possesses electro receptors over the entire head, the dorsal and ventral regions of the body, but absent from the side and the caudal peduncle where the electric organ is located (Ref. 10011). Also sensitive to sound frequencies (Ref. 10831).
棲息於浮游植物堆的岸邊的植叢而且迴游到上面洪泛區產卵。 底部攝取食物的食蟲動物。 (參考文獻 28714) 持有在整個頭，背部與腹面身體的區域上的電容器, 但是發電器官所在的體側與尾梗沒有出現.(參考文獻 10011) 也敏感聲音頻率。 (參考文獻 10831)
