Africa: a very wide distribution area which includes most of the West African river basins (Ref. 81274), the White Nile, Uebi Shebeli and Juba (Ref. 3203), and the Congo River basin (Ref. 52193). In southern Africa, restricted to the middle and lower Zambezi, Buzi and Pungwe (Ref. 52193). Also known from Lake Malawi, Lake Tanganyika and Lake Albert [former Lake Mobuto] (Ref. 3203, 52193).

Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 21 - 33; Duri dubur: 0; Sirip dubur lunak: 38 - 51. Diagnosis: head depressed (Ref. 13337, 52193). Body elongated (Ref. 2915, 13337, 52193), shallow (Ref. 28714), ratio standard length/body depth 4.9-7.5 (Ref. 81274). Mouth large (Ref. 13337, 52193) and terminal (Ref. 13337, 28714, 52193, 81274), with 16-28 teeth in upper, and 14-28 in lower jaw (the number of teeth increases with size) (Ref. 81274). Chin (mental swelling) absent (Ref. 52193). Origin of dorsal fin behind origin of anal fin, nearer caudal fin base than tip of snout (Ref. 4903, 52193). Dorsal fin shorter than anal fin; mouth width subequal to snout length (Ref. 52193). Snout long (Ref. 52193), rounded, its length 1/5-1/4 that of the head (Ref. 4903), almost as broad as head (Ref. 2915, 81274). 21-33 dorsal- and 38-50 anal-fin rays (Ref. 52193, 81274). Head 3.4-5.1 times in standard length; interorbital space relatively broad, ratio head length/interorbital width 2.9-6.8; wide ranges for most of the meristic characters are caused by the existence of geographical clines (Ref. 2915, 81274).
Body shape (shape guide): elongated; Cross section: compressed.

Juveniles occur in marginal habitats, adults prefer deep quiet water between boulders and below overhangs, away from strong currents; also occurs beneath Salvinia mats and in river estuaries in Lake Kariba; juveniles prey on invertebrates, mainly shrimps and insect larvae (Ref. 7248, 52193). Adults/larger individuals are piscivorous (Ref. 28714), feeding on small cichlids, minnows and labeos (Ref. Ref. 7248, 52193). May live for 8 years or more; breeds in summer during the rainy season; mature females carry 25000 or more eggs (Ref. 7248, 52193). A fractional spawner (Ref. 10606, 10605). Affinities: M. breviceps.
