Estimates based on models
Preferred temperature (Ref.
123201): 1.8 - 3.2, mean 2.5 °C (based on 30 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00046 (0.00020 - 0.00105), b=3.12 (2.92 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
