Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00336 - 0.01491), b=3.01 (2.84 - 3.18), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.1 ±0.3 se; based on size and trophs of closest relatives

Resiliência (Ref. 120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
