Estimates based on models

Preferred temperature (Ref. 123201): 0.3 - 10.8, mean 1.8 °C (based on 41 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 4.2 ±0.7 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).
