; air tawar dasar (demersal); pH range: ? - 7.0; dH range: ? - 10. Tropical; 26°C - 28°C (Ref. 2060); 7°N - 10°S
Africa: coastal rivers of the Gulf of Guinea, from Guinea Bissau to Liberia and upper Cavally River in Côte d'Ivoire; also in upper Casamance River in Senegal (Ref. 28149, 81263). Reports from the Congo River basin (Ref. 44840, 51193) and Democratic Republic of the Congo (Ref. 4537) probably refer to Polypterus polli, previously a subspecies of Polypterus palmas, and only known from the Congo River basin (Ref. 28149).

Diagnosis: Polypterus palmas is distinguished from other species of the genus by the upper jaw longer than lower jaw, pectoral fin not reaching the level of the first dorsal fin ray and 27-32 scales between occiput and first dorsal fin ray (Ref. 2835, 28149, 42908, 81263).

Trophic level (Ref.
69278): 2.9 ±0.43 se; based on food items.
Daya lenting (Ref.
