Africa: endemic to the Pra basin in Ghana; other reports from West Africa unconfirmed (Ref. 7324, 57126). Identifications of C. walkeri in Lower Guinea appear to be misidentifications of mature male of C. auratus, or of C. aluuensis or C. thysi (Ref. 81642).

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=0.01000 (0.00579 - 0.01726), b=3.02 (2.87 - 3.17), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.40 se; based on food items.

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (K=0.72).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Unknown.
