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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.6   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100).
