Dorsale stekels (totaal): 4 - 6; Dorsale zachte stralen (totaal): 7-9; Anale stekels 1; Anale zachte stralen: 16 - 20; Wervels: 47 - 49. Scales in lateral series above lateral band 47-53; and predorsal scales 24-26 (Ref. 47314).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00275 - 0.01321), 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):  3.6   ±0.3 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 (22 of 100).
