Estimates based on models
Preferred temperature (Ref.
123201): 26.9 - 28.8, mean 28 °C (based on 232 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02692 (0.01132 - 0.06402), b=2.94 (2.74 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
