Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

South America: Amazon, Orinoco, Paraná, Paraguay, and São Francisco River basins and rivers fo Guianas.

Occupies very diverse biotopes and carries out its biological cycle in freshwater as well as in brackish water (Ref. 27188). Juveniles feed on larvae of crustaceans (especially Macrobrachium), aquatic insects and copepods. Adults prey on fish. Captured during the rainy season (Ref. 35237).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00891 (-0.02259 - 0.04041), b=3.08 (3.06 - 3.10), based on LWR estimates for this species (Ref. 93245).

Trophic Level (Ref. 69278): 4.4 ±0.8 se; Based on diet studies.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.11-0.22; tm=1-1.5).

Vulnerability (Ref. 59153): High to very high vulnerability (68 of 100) .

Price category (Ref. 80766): Medium.
