简单描述
检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 1. Diagnosis: adipose fin always present; anterior nostrils closer to each other than posterior ones; snout reaching slightly beyond lower jaw; nasal barbel always reaching beyond orbit; eyes rather large (horizontal diameter 26,8-33,1% HL); inner side of pectoral spine feebly serrated (Ref. 43912).
Confined to larger lakes and rivers; possibly a shoaling species; polyphagous with a frugivorous tendency; stomach contents examined showed the presence of sand, mud, benthic vegetable remains, leaves, fruits and insect remains (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Probably of economic importance locally for fishermen of Lake Tumba; maximum reported TL 280mm (Ref. 43912).
