Africa: Sudanian species - Senegal, Gambia, Niger (downstream from Bamako), Volta, Chad. Unlike Distichodus rostratus, it is not found in the lower basins of the Volta and other coastal basins between Gambia and Niger. Also found in the White Nile.
Maximum TL was recorded at 70 cm (Ref. 7094). Prefers flowing water. Feeds on vegetation and periphyton (Ref. 28714).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01642 (-0.17853 - 0.21137), b=3.01 (2.90 - 3.12), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278): 2.0 ±0.00 se; Based on food items.
Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100) .
