Short description Morphology | Morphometrics

Dorsal spines (total): 11 - 14; Anal spines: 0; Anal soft rays: 14 - 18; Vertebrae: 53 - 57. Diagnosis: Polypterus endlicherii is characterized by a lower jaw longer than upper jaw and a pectoral fin reaching the first dorsal ray (Ref. 2835, 42908, 81263).

Inhabits swamps and rivers. This species is essentially a piscivorous (Ref. 9695, 28714). Diet includes snails and crustaceans (Ref. 30488).

Estimates based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00437 (0.00272 - 0.00701), b=3.08 (2.94 - 3.22), in cm total length, based on LWR estimates for species & Subfamily-BS (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.63 se; based on food items.
