Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00267 - 0.01964), b=3.00 (2.76 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.6 ±0.6 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Preliminary low fecundity).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (43 of 100).
