Estimates based on models
Preferred temperature (Ref.
123201): 9.6 - 15.3, mean 13.2 °C (based on 37 cells).
Phylogenetic diversity index (Ref.

50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00172 - 0.01163), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
