Estimates based on models

Preferred temperature (Ref. 123201): 1.6 - 2.3, mean 1.8 °C (based on 657 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.1 ±0.6 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (51 of 100).
