Estimates based on models

Preferred temperature (Ref. 123201): 7.7 - 15.1, mean 10.6 °C (based on 338 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00115 (0.00043 - 0.00304), b=3.07 (2.83 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
