Estimates based on models
Preferred temperature (Ref.
123201): 2.6 - 4.7, mean 3.3 °C (based on 21 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00224 (0.00091 - 0.00552), b=3.08 (2.86 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
