Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00774 - 0.05639), b=3.03 (2.79 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Niveau trophique (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fecundity 60-70).
Fishing Vulnerability (Ref.
