Estimates based on models
Preferred temperature (参照
123201): 3.7 - 7.1, mean 5.2 °C (based on 28 cells).
Phylogenetic diversity index (参照
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00495 - 0.02022), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
