Estimates based on models
Preferred temperature (Ref.
123201): 24.9 - 29.3, mean 28.2 °C (based on 900 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01123 - 0.04892), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
