Estimates based on models
Preferred temperature (Ref.
123201): 3.3 - 9.6, mean 5.8 °C (based on 761 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00111 - 0.00431), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
