Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 8; Rayons mous dorsaux (Total) : 16 - 17; Épines anales: 3; Rayons mous anaux: 14. This species is characterized by the following features: Cheek and breast naked; fully scaled dorsolateral body surface; anteroventral profile of the lower jaw usually strongly concave; upper oral valve with minute, sparse, slender projections; bicuspid or tricuspid preorbital spine, expanded distally; elongated second dorsal fin spine, reaching beyond base of fifth soft ray when fin is appressed; second anal fin spine not elongated, not extending to the base of fifth soft ray when fin appressed (Ref. 74926).

Estimates based on models

Preferred temperature (Ref. 123201): 28.4 - 29.2, mean 28.9 °C (based on 156 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01862 (0.00823 - 0.04215), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.9 ±0.3 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 (10 of 100).
