Estimates based on models
Preferred temperature (Ref.
123201): -1.3 - 5.3, mean 0.9 °C (based on 783 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00328 - 0.01160), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
