Eponymy: Michael ‘Mike’ J Mann was the FAO Fisheries Officer in Kenya. He was the first to report the presence of this species in the Tana River, Kenya (1968). He wrote: A Preliminary Report on a Survey of the Fisheries of the Tana River, Kenya (1967). (Ref. 128868), visit book page.

Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 3; Raggi dorsali molli (totale) : 7; Spine anali: 0; Raggi anali molli: 11 - 12. Moderately sized species; snout rounded; lips give a distinctive horseshoe-shaped appearance to mouth in ventral view and with prominent lateral lobes; snout long (58.8-68.8%HL), 6-8 long teeth, each tooth curved distally upwards; maxillary barbel with a distinct marginal membrane at base and with well-developed thin tuberculate branches on anterior side; adipose fin well developed and separated from dorsal fin by a distance measuring 16.4-22.3%SL (Ref. 39831). Overall coloration of adult fish light brown with a white belly, caudal fin brownish, young fish brownish with irregular, broad white dendritic streaks on the flanks (Ref. 39831).
Body shape (shape guide): fusiform / normal.
Synodontis manni was only found in the main river of the Lower Tana drainage. According to local fishermen it is most abundant in deeper waters of the river where it lives near large logs and stranded trees (Ref. 39831). Oviparous (Ref. 205).
