Estimates based on models
Preferred temperature (Ref.
123201): 1 - 4.5, mean 3.8 °C (based on 49 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00386 - 0.01635), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Generation time: 9.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Weerstandsvermogen (Ref.
