Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 56 - 62; Duri dubur: 0; Sirip dubur lunak: 50 - 58; vertebrata, bertulang belakang: 56 - 60. Diagnosis: Characterized by a relatively long vomerine tooth plate (5.9-14.4% of head length) and by a relatively short adipose fin (5.9-12.5% of standard length), the length of which is a specific character of Clarias 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 (Ref. 248). It is distinguished from Clarias gariepinus by having a short adipose fin behind the rayed dorsal and an ovoid vomerine toothplate with granular or blunt teeth (Ref. 52193).


Body shape (shape guide): elongated; Cross section: oval.

Biologi     Daftar kata (contoh epibenthic)

Facultative air-breathing (Ref. 126274); 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).

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