16-21个下颚齿。 上颌骨触须达到肱骨突起的后顶端, 或者偶然地超过。 颚骨触须有细长的分支。 略灰色的银色, 有深色的可变大小的斑点。 尾鳍偶然有斑点.(参考文献 34290)
Occurs in rivers and lakes and prefers deeper water (0-80 m) (Ref. 34291), although it also occurs in shallow water (Ref. 34290). In Lake Victoria it occurs over hard and soft substrates, but is more common over soft bottoms and in water over 13 m deep; feeds on gastropod molluscs and insects (mainly chironomid larvae), and to a minor extent on fishes and ostracoda; able to extract the flesh of snails without crushing their shells (Ref. 12526). Rarely grows to lengths greater than 35 cm SL (Ref. 34290). Oviparous (Ref. 205).
