Estimates based on models
Preferred temperature (Ref.
123201): 14.1 - 24.7, mean 23.8 °C (based on 198 cells).
Fylogenetische diversiteitsindex (Ref.

50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00413 - 0.01752), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.6 ±0.3 se; based on diet studies.
Generation time: 1.1 ( na - na) years. Estimated as median ln(3)/K based on 1
