Issue
Affinities: most similar to M. elongatus, from which it differs in the presence of multicuspid (vs conical, monocuspid) inner dentary teeth, inner premaxillary and outer dentary teeth with greater number of cusps and a slightly more robus body (Ref. 80290).

Africa: Congo, Okavango, Zambezi (Ref. 7248, 120641), Kunene and east coast rivers south to the Pongolo (Ref. 7248), Cross and Sanaga Rivers (Ref. 80290) and Tanzania (Ref. 4967). Nilo-Sudan and West-African reports of M. acutidens (e.g. Ref. 367, 51193) are misidentifications of M. elongatus (see DVD version of Ref. 81279; see also Ref. 2880).

Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 10 - 11; Espinas anales: 0; Radios blandos anales: 17 - 20. Diagnosis: inner dentary teeth multicuspid; 14-17 anal fin branched rays; dorsal fin apical tip black; scales of flank without melanophores concentrated along basal margin, pigment diffuse or absent (Ref. 80290).

Shoals in clear, flowing or standing, open water; appears to co-exist with the tigerfish Hydrocynus forskalii in open water although it is heavily preyed upon by that predator, particularly those shoals of tigerfish ranging up to 45 cm in length (Ref. 13337). Omnivorous, often feeding from surface waters on winged insects; also takes insect larvae, crustaceans and eggs and fry of other fish (Ref. 13337). Matures after a year; partial spawner of moderate fecundity, with usually fewer than 700 eggs per female; shoals migrate upstream after first summer rains; breeds throughout the summer months; used as forage fish and as bait for tigerfish and pike (Ref. 7248).
