Duri punggung (Keseluruhan (total)) : 1; Sirip dubur lunak: 59 - 73; vertebrata, bertulang belakang: 50 - 57. Diagnosis: 13-16 gill rakers on lower limb of first gill arch; 57-75 branched anal-fin rays; eyes positioned dorso-laterally; adipose fin always absent (Ref. 43912, 57127, 81643). Often with a post-occipital hump, a character also sometimes found in Schilbe intermedius whose head profile is extremely variable (Ref. 57127, 81643). Posterior nostrils closer to each other than are anterior ones; nasal barbel at maximum reaching to midway between eye and opercle, but generally shorter; inner side of pectoral spine feebly serrated (Ref. 43912).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Adapted to riverine and lacustrine conditions. Adults live mainly in the open waters; predatory, carnivorous but not strictly piscivorous. Young are essentially entomophagous (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Of some economic value to the fishermen especially in the Chad basin (Ref. 43912). Maximum reported total length 45 cm (Nile basin)(Ref. 43912).
Distinct pairing (Ref. 205).
