Estimates based on models
Preferred temperature (Ref.
123201): 8.7 - 17.9, mean 10.7 °C (based on 200 cells).
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00237 - 0.01161), b=3.15 (2.96 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
