Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00089 (0.00039 - 0.00204), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.9 ±0.7 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
