Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 14 - 16; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 15 - 17. Diagnosis: Small, fairly slender fishes, depth around 22-24% of standard length; belly rounded, smooth, no trace of scutes before or behind pelvic fins; pelvic scute itself present, however, the tips of its lateral arms bifurcated; jaws about equal, with fine teeth; no second supra-maxilla; lower gillrakers 10 to 12; pelvic fin insertion just behind dorsal fin origin (Ref. 188). Scales large, 20-22 in longitudinal series (Ref. 188, 93833). Congothrissa gossei occurs with other clupeid species, but the smoothly rounded belly, absence of spiny post-pelvic scutes and lack of a second supra-maxilla makes it unmistakable (Ref. 188).
A riverine species apparently found in the main stream of the Congo River (Ref. 188). It feeds on small shrimps, mosquito larvae and chironomid larvae (Ref. 188).
