Estimates based on models
Preferred temperature (Ref.
123201): 3.9 - 8.8, mean 4.6 °C (based on 40 cells).
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00118 - 0.00673), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
