Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01660 (0.00760 - 0.03623), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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