Africa: very widespread, within the drainage basin of the Nile (Ref. 1440, 2801, 28714), Chad, Niger-Bénoué, Volta, Senegal and Gambia basins, as well as Cross River (Ref. 1440, 2940, 81282). Report from Cameroon coastal rivers (Ref. 1440) unconfirmed in Ref 81639. Not reliable known from the Congo River basin (Ref. 1440) and one controversial record from the East coast of Africa (Ref. 1440). Ref. 2801 reports presence in Warri (Nigeria) and Kingani (Tanzania).

Bayesian length-weight: a=0.01023 (0.00806 - 0.01300), b=3.03 (2.99 - 3.07), in cm total length, based on LWR estimates for this species (Ref.
93245).
Generation time: 5.5 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
