Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 2; Raggi dorsali molli (totale) : 9; Spine anali: 3 - 5; Raggi anali molli: 21 - 27. Possesses a humeral spot shaped as an oval or inverted teardrop, occupying not less than a quarter of the height of the body; caudal peduncle with a black spot covering between one third and almost the totality of its depth (Ref. 52916).

Attains a length of around 20 cm. As indicated by its dentition and body form, it is a formidable predator which feeds exclusively on fish. A ubiquitous species, but frequently found throughout the length of waters with moderate flow. Reproduction begins with the onset of the rainy season (Ref. 12225).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00421 - 0.01086), b=3.15 (3.01 - 3.29), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.73 se; based on food items.

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (20 of 100).

Price category (Ref. 80766): Unknown.
