Africa: Chad, Niger, Volta, Gambia and Senegal basins, including the Nile. Also known from Côte d'Ivoire (Ref. 272).

Biology     Glossary (e.g. epibenthic)

Affinities: P. pellegrini. Generates electric organ discharge (EOD) of short duration that seems to correlate with aggregative behavior of the species (Ref. 14060; 10601). EOD temporal pattern cues have been shown to play a role in species recognition for P. bovei (Ref. 10600). A ratio measure between olfactory and visual receptor areas suggests that this species relies more on visual than olfactory information (Ref. 10839). A fractional spawner (Ref. 10605; 10606).

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=0.01479 (0.00801 - 0.02732), b=2.85 (2.69 - 3.01), based on LWR estimates for species & Genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.4 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (K=0.53-1.10; tmax=2.5).
Vulnerability (Ref. 59153):  Low vulnerability (13 of 100) .
Price category (Ref. 80766):   Unknown.
