Estimates based on models
Preferred temperature (Ref.
123201): 15.7 - 22.3, mean 18.1 °C (based on 26 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00780 - 0.04657), b=3.03 (2.82 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.1 ±0.3 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
