Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 3 - 4; Anal soft rays: 76 - 85; Vertebrae: 56 - 58. Head width 11.4-13.3% SL; caudal peduncle depth 3.7-4.3% SL; anal fin rays 76-85; vertebrae 56-58 (Ref. 52514).

Inhabits large, slow flowing rivers and lakes (Ref. 52514) and swamps (Ref. 56749). Juveniles sometimes occur in smaller streams (Ref. 52514). Feeds on smaller fishes and crustaceans (Ref. 52514).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00562 (0.00278 - 0.01137), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (16 of 100).
