Short description Morfología | Morfometría

Espinas dorsales (total): 0; Radios blandos dorsales (total): 56-62; Radios blandos anales: 50 - 58; Vértebra: 56 - 60. Characterized by a relatively long vomerine tooth plate (5.9-14.4 % HL) and by a relatively short adipose fin (5.9-12.5 % SL), the length of which is a specific character of C. ngamensis. Head oval to rectangular in dorsal outline; frontal fontanelle long and narrow (`knife-shaped'); occipital fontanelle small and oval-shaped. Pectoral spine robust and slightly curved. The suprabranchial organ consists of well developed arborescent structures.

Biología     Glosario (por ej. epibenthic)

The species seems to be nowhere especially abundant but is fairly common in some areas such as weed beds, permanent swamps, quieter waters and muddy bottoms (Ref. 248, 5595). Prefers vegetated habitats. Feeding habits overlap considerably with the sharptooth catfish. Important foods are mollusks, terrestrial and aquatic insects, insect larvae, shrimps, grain, crabs and fish (Ref. 4967, 78218). Feeds on snails (Ref. 5595). Hard-shelled foods such as mussels are crushed before they are swallowed. Breeds during the summer rainy season. May live for 5-6 years (Ref. 7248). Also caught with drawnets (Ref. 4967).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Breeding is reportedly flood dependent and similar to that of C. gariepinus.
