Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00366 - 0.01891), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.7 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
