Estimates based on models
Preferred temperature (Ref.
123201): 4.8 - 6.9, mean 5.3 °C (based on 9 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00179 - 0.01169), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
