Africa: present throughout intertropical Africa (Ref. 2880, 80290, 81279). Absence from the Gambia basin is noteworthy (Ref. 81279). Present in the Nile system (Ref. 28714, 58460) up to Lake Albert (Ref. 4903) and in Lake Turkana system (Ref. 28663). Widely distributed in the Congo River basin (Ref. 5331, 42019, 42510, 45434).

More common in rivers than lakes; feeds on insects, crustaceans, fish, vegetation and debris (Ref. 28714). Considering the distribution of different forms (according to collection determinations), it should be noted that a B. macrolepidotus 'form' is found only in northern regions, while a B. schoutedi 'form' is found only in southern regions. However, between these two forms there appears to be mixing and intermediacy of forms. We consider that there are several populations which have evolved in a geographical gradient to produce different morphotypes of a single species (Ref. 80290).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00804 - 0.01428), b=2.97 (2.92 - 3.02), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  2.8   ±0.35 se; based on food items.
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Daya lenting (Ref. 120179):  Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (31 of 100).
