Estimates based on models
Preferred temperature (Ref.
123201): 2.5 - 11.7, mean 6.4 °C (based on 72 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00163 - 0.00884), b=3.16 (2.96 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
