Estimates based on models
Preferred temperature (Ref.
123201): 6.6 - 15.5, mean 10.1 °C (based on 302 cells).
Phylogenetic diversity index (Ref.

50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01031 - 0.05092), b=2.94 (2.74 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
