Estimates based on models

Preferred temperature (Ref. 115969): 2.2 - 5.3, mean 3.3 (based on 86 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5313   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00144 - 0.00836), b=3.15 (2.94 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.80 se; based on food items.
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
