Short description Morfologia | Morfometria

Spine dorsali (totale): 15 - 17; Raggi dorsali molli (totale): 11-12; Spine anali 3; Raggi anali molli: 8 - 10; Vertebre: 29. Diagnosis: outer teeth of jaws in females and young males bicuspid except a few lateral unicuspids, but mature males with many unicuspids, until at about 20cm SL nearly all outer teeth are unicuspid and the posterior are enlarged; pharyngeal teeth fine and dense, with blade of lower pharyngeal bone longer than toothed area; 21-26 gill-rakers on lower part of first arch; 29 vertebrae; 15-16, rarely 17 dorsal spines; total dorsal rays 27 or 28; caudal fin not scaly; genital papilla in both sexes complex, in the male elongate, bifid and tasselled; white spots on pelvic fins of mature males and on dorsal, anal and base of caudal in both sexes; dentition and coloration of mature males diagnostic (Ref. 2).

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=0.01905 (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).
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (15 of 100).
