Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00573 - 0.02198), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

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