Estimates based on models
Preferred temperature (Ref.
123201): -0.3 - 1.7, mean 0.8 °C (based on 4494 cells).
Fylogenetische diversiteitsindex (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00120 (0.00057 - 0.00252), b=3.10 (2.91 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
