Estimates based on models
Preferred temperature (Ref.
123201): 2.5 - 3.8, mean 3.1 °C (based on 115 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00511 - 0.02146), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
