Épines dorsales (Total) : 15 - 17; Rayons mous dorsaux (Total) : 9 - 11; Épines anales: 3; Rayons mous anaux: 8 - 10. Body relatively deep; head large (Ref. 40031). Jaws isognathous (Ref. 40031). Lips greatly enlarged (Ref. 40031, 54524), soft, and deeply folded back onto snout and lower jaw (Ref. 40031). Premaxillary pedicel not prominent (Ref. 40031). Teeth in outer rows of upper and lower jaws bicuspid, relatively closely set (Ref. 40031). Pectoral fin relatively long, extending past base of third anal fin spine to base of seventh anal fin ray (Ref. 40031). Caudal fin scaled more than three quarters of fin length near dorsal and ventral edges (Ref. 40031).

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=0.01905 (0.00827 - 0.04391), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.5 ±0.4 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).
