Estimates based on models
Preferred temperature (Ref.
123201): 0.8 - 7, mean 4.1 °C (based on 300 cells).
Phylogenetic diversity index (Ref.

50 = 1.2500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.01094 - 0.03320), b=2.99 (2.83 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.

Trophic level (Ref.
69278): 4.5 ±0.37 se; based on food items.
Generation time: 14.8 ( na - na) years. Estimated as median ln(3)/K based on 1
