Short description
Morfologia | Morfometria
Raggi dorsali molli (totale): 3-4; Raggi anali molli: 76 - 85; Vertebre: 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): PD
50 = 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
Resilienza (Ref.
120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
