Estimates based on models

Preferred temperature (Ref. 123201): 1.8 - 2.7, mean 2.3 °C (based on 533 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.2 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).
