Etymology: Sarotherodon: Greek, saros, -ou = sawdust + Greek, ther = animal * Greek, odous = teeth (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecologia
; Água doce demersal. Tropical; 25°C - 27°C (Ref. 12468); 5°N - 4°N
Africa: Lake Barombi Mbo (Ref. 4999, 81260), a tributary of the Kake River (affluent of Lake Barombi Mbo) (Ref. 81260) and Kumba stream (tributary of the outlet of Barombi Mbo) (Ref. 4999), in west Cameroon.
Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 16.2 cm SL macho/indeterminado; (Ref. 81260)
Espinhos dorsais (total): 15 - 17; Raios dorsais moles (total): 10-12; Espinhos anais 3; Raios anais moles: 8 - 10; Vértebras: 29. Diagnosis: 14-18 rakers on lower limb of first arch; 30-31 scales in lateral line (Ref. 81260). Body silver-grey, with mid-lateral black band interrupted anteriorly on caudal peduncle (Ref. 2, 81260). Head length 33.0-38.4% of standard length; jaw teeth with slender shafts and broad crowns (Ref. 81260). Mature fishes of both sexes with variable black areas on lower jaw and lower parts of head; no tilapia-mark (Ref. 2).
Found throughout the lake, but seems to prefer zones with submerged wooden or stone structures (Ref. 52307). Usually forms schools at the surface; feeds mainly on epiphytic and epilithic filamentous algae, and the diatoms, rhizopods, rotifers and organic debris found among them; adults feed by opening their mouths very wide and applying them to the surface of the rock as though sucking the material in (Ref. 2). Lacks marked sexual dichromatism when sexually active (Ref. 81260). Both sexes are possible incubators (Ref. 52307). Forms temporary pair bonds (Ref. 81260), for the entire duration of incubation/broodcare (Ref. 52307).

Absence of sexual dichromatism suggests a biparental mouth-brooding function.
