Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 27 - 29; Anale stekels: 0; Anale zachte stralen: 14 - 15. Diagnosis: snout extended; mouth terminal; head about 4 times in fork length; juveniles with 6-7 dark bars (Ref. 52193).

Inhabits swift flowing water, rapids or quiet, deep, sandy or rocky pools (Ref. 13337). Found only in the mainstream of larger rivers and even in Lake Kariba prefers more riverine habitats; omnivorous, feeds on insects, snails, small fish, and aquatic plants; breeds in summer, moving upstream to suitable sites (Ref. 7248, 52193).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01549 (0.00716 - 0.03351), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.2 ±0.49 se; based on food items.

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).

Prijsklasse (Ref. 80766): Unknown.
