Short description Morfologia | Morfometria

Spine anali 0; Raggi anali molli: 18 - 22. Diagnosis: lateral line complete, 23-29 (Ref. 81279) or 26-29 (Ref. 80290) lateral line scales. Anal fin with 3 unbranched and 15-19 (Ref. 81279) or 16-19 (Ref. 80290) branched rays. 11-14 gill rakers on lower part of first branchial arch; 6/8 premaxillary teeth (Ref. 2880, 81279). Inner dentary teeth conical, monocuspid; scales of flank without melanophores concentrated along basal margin, pigment diffuse or absent (Ref. 80290). Fins colorless, at most, pinkish; caudal fin tinged with pink (Ref. 2880, 81279). Tip of dorsal fin usually blackish (Ref. 2880, 80290, 81279). Widely distributed, never found in Cavally River (Ref. 2880, 81279).

Biologia     Glossario (es. epibenthic)

Inhabits fringing vegetation of rivers and lakes, feeding on zooplankton, beetles and other insects (Ref. 28714). Often reported in West Africa under name of M. acutidens. Affinities: most similar to M. acutidens, from which it differs in the presence of conical, monocuspid (vs multicuspid) inner dentary teeth, inner premaxillary and outer dentary with fewer cusps, and a slightly more slender body (Ref. 80290).
