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=0.01514 (0.00712 - 0.03216), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
回復力 (Ref. 120179):  非常低的, 最小族群倍增時間超過14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (56 of 100).
