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=0.00380 (0.00147 - 0.00981), b=3.11 (2.88 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
