Short description Morfologia | Morfometria

Spine dorsali (totale): 5 - 7; Spine anali 0; Raggi anali molli: 14; Vertebre: 50 - 56. Cylindrical body (Ref. 28149, Ref. 46409). Upper jaw a little longer than lower jaw (Ref. 28149). Number of dorsal finlets: 5-7 (Ref. 28149, Ref. 51884); used to distinguish Polypterus palmas polli from P. p. palmas and P. p. buettikoferi (Ref. 28149). Pectoral fin not reaching dorsal fin origin (Ref. 28149). Ganoid scales (Ref. 42904): 52-55 lateral line scales, 32-39 scales around body, 22-28 predorsal scales (Ref. 28149, Ref. 51884). Dorsal surface and flanks with large black blotches, forming a dense reticulate pattern, ventral surface uniform pale (Ref. 28149). The fleshy base of the pectoral fin with a large grey to black spot (Ref. 28149, Ref. 46409). Dorsal fin spotted, pectoral fin with a striped pattern in some specimens, pelvic fin pale and anal fin sometimes slightly colored (Ref. 28149).

Facultative air-breathing (Ref. 126274); This entomophagous fish lives in swamps and zones of flood (Ref. 41580).

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).

Trophic level (Ref. 69278): 3.2 ±0.40 se; based on food items.

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100).
