Estimates based on models
Preferred temperature (Ref.
123201): 1.1 - 6.8, mean 4.5 °C (based on 226 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00729 - 0.02077), b=3.02 (2.87 - 3.17), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
