Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal soft rays: 12 - 13; Vertebrae: 51 - 54. Distinguished from its congeners by a unique combination of the following characters: length of dorsal-fin base 13.7-16.7% SL, dorsal to adipose distance 8.6-14.2% SL, interorbital distance 28.4-31.8% HL, eye diameter 9.2-11.3% HL and a rounded snout (Ref. 41209).

Occurs in deeper rocky areas and tree roots (Ref. 37771). Species caught throughout the year. Enters flooded forest during the months of high water (July-October). Feeds on fish, shrimps and crabs (Ref. 9497).

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=0.01413 (0.00741 - 0.02693), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.67 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).

Price category (Ref. 80766): Unknown.
