Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 69 - 94; Radios blandos anales: 52 - 70; Vértebra: 56 - 61. Diagnosis: body less elongate, its maximum depth 11.9-16.4% SL (m=14.1); head length 21.0-26.0% SL (m=24.1) (Ref. 57129, 81644). Head rectangular dorsally; snout extremely broadly rounded; eyes more laterally placed (Ref. 248). Interorbital distance 45.4-54.3% HL (m=48.8) (Ref. 57129, 81644). Tooth plates extremely broad (Ref. 248), width of premaxillary tooth plate 30.4-38.9% HL (m=34.9), and of vomerine tooth plate 26.1-33.9% HL (m=29.7)(Ref. 57129, 81644). Frontal fontanel long and narrow; occipital fontanelle long and oval-shaped (Ref. 248). Supraorbital and "dermosphenotic" bones separated in specimens up to 200 mm SL, in larger specimens they usually become joined (Ref. 248, 101841)). 7-13 (Ref. 57129, 81644) or 7-14 (Ref. 101841) gill rakers on first gill arch. Suprabranchial organ well developed (Ref. 248, 101841). Pectoral spine slender, its outer side showing strong downward serrations (Ref. 248, 81644). Dorsal fin length 59.5-67.9% SL; distance from dorsal to caudal fin 1.2-4.3% SL (Ref. 57129, 101841). Flank neuromasts arranged in a regular pattern (Ref. 81644). Colouration: no information on colour in life (Ref. 57129, 101841). Preserved specimens: dark brown on back and sides and pale brown to beige/whitish on belly; pectoral and pelvic fins sometimes with a pale distal band; caudal fin sometimes with alternating light and dark vertical bars (Ref. 57129, 81644). Never an irregular pattern of small white spots on body (Ref. 101841).

Facultative air-breathing (Ref. 126274); Data on the diet of C. walkeri (=C. camerunensis) showed larvae of mayflies, chironomids, and caddis insects to be the main food of small and middle-sized specimens (Ref. 248). Stomach content analysis showed presence of practically everything edible from plant remains, insects and their larvae to fish remains (Ref. 78218).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00343 - 0.01757), b=2.97 (2.79 - 3.15), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.5 ±0.51 se; based on food items.

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100).
