Taille / Poids / Âge
Maturity: Lm ?  range ? - ? cm
Max length : 20.2 cm SL mâle / non sexé; (Ref. 81260)
Épines dorsales (Total): 14 - 16; Rayons mous dorsaux (Total): 9-12; Épines anales 3; Rayons mous anaux: 8 - 10. Diagnosis: 20-24 rakers on lower limb of first arch; length of lower pharyngeal jaw < 43.5% of head length; 27-30 scales in lateral line; head length 33.6-39.5% of standard length; total dorsal rays (including spines) 24-27 (Ref. 81260). Color in life is silver-grey, darker on back, whitish below with a series of pink spots along flank, one to each scale; genital papilla small and leaf-shaped in male, truncate in female; tips of dorsal soft rays reaching vertical of 0.25 to 0.75 length of caudal, anal not quite so far; pelvic extremity reaching vent or nearly (Ref. 2).
Lacks marked sexual dichromatism when sexually active; forms temporary pair bonds (Ref. 81260).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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): 2.2 ±0.1 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.
