Dorsale stekels (totaal): 14 - 15; Dorsale zachte stralen (totaal): 14-16; Anale stekels 3; Anale zachte stralen: 10 - 11. Diagnosis: lower pharyngeal bone about as long as broad, with anterior lamella shorter than toothed area; median pharyngeal teeth broadened when compared to lateral teeth; 3-4 series of scales on cheeks; 4-4.5 scales between first dorsal fin spine and upper lateral line (Ref. 53405).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.7500 [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).
Trofisch niveau (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (15 of 100).
