Estimates based on models
Preferred temperature (Ref.
123201): 18.4 - 21.4, mean 18.9 °C (based on 13 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00366 - 0.01807), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
