Description synthétique Clés d'identification | Morphologie | Morphométrie

Rayons mous dorsaux (Total) : 117; Rayons mous anaux: 89; Vertèbres: 75. This species is distinguished from the Atlantic species by having fewer rays in the dorsal 117 (vs. 135-158) and anal 89 (vs. 106-122) fins; head squamation restricted to the middle part of the preopercle (vs. head almost fully scaled - over the dorsum, preopercle and the opercle in part); a distinct spine behind the posterior nostril (vs. spine hardly visible); 9 spines on the hind margin of the preopercle (vs. 4-7 spines) (Ref. 87601).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00110 (0.00041 - 0.00296), b=3.08 (2.85 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).
