Estimates based on models

Preferred temperature (Ref. 123201): 2.2 - 5.3, mean 3.3 °C (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).
