Etymology: Polypterus: Greek, poly = a lot of + Greek, pteron = wing, fin (Ref. 45335).
This species is a synonym of Polypterus endlicherii Heckel, 1847 in Eschmeyer (Eschmeyer (CofF ver. Sep. 2011: Ref. 88002): Ref. 88002).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; depth range 0 - 10 m (Ref. 36901). Tropical
Africa: widespread in the Congo River basin; also present in Lake Tanganyika (Ref. 43033, 88113).

Morphology | Morphometrics
(total): 12 - 15;
spines: 12-15. Compressed body (Ref. 42908, Ref. 43035). Lower jaw prominent, longer than upper jaw (Ref. 36901). Number of dorsal finlets: 12-15 (Ref. 42908). Pectoral fin reaching dorsal fin origin (Ref. 45485). Ganoid scales (Ref. 42904, Ref. 43035): 55-59 lateral line scales, 46-52 scales around body, 11-16 predorsal scales (Ref. 2970, Ref. 36901, Ref. 42908, Ref. 44840, Ref. 45485). Dorsal side gray colored, ventral side paler, yellowish, with 6 to 9 darker transversal bars (Ref. 41580, Ref. 43035). Fins with weak blackish spots (Ref. 41580).
This carnivorous fish lives in streams, lakes and zones of flood (Ref. 4910, Ref. 41580). In Lake Tanganyika it is mostly found at the mouth or delta of rivers and lagoons (Ref. 36901). Not commercially important (Ref. 4967).
