Estimates based on models

Preferred temperature (Ref. 123201): 1.4 - 10.3, mean 6.4 °C (based on 270 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01349 (0.00537 - 0.03387), b=3.02 (2.80 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.58 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100).
