Estimates based on models
Preferred temperature (Ref.
123201): 11.6 - 20.1, mean 15.4 °C (based on 120 cells).
Fylogenetische diversiteitsindex (Ref.

50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00157 - 0.01056), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
