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).

背面の脊椎 (合計) : 7 - 10; 肛門の骨: 12 - 14; 脊つい: 56 - 59. 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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00195 - 0.01073), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  2.9   ±0.43 se; based on food items.
回復力 (Ref. 120179):  低い, ４．５年～１４年の倍増期間の最小個体群 (Fec=5 observed in Aquatium is probably too low; assuming > 10 fecundity (RF)).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100).
