Estimates based on models
Preferred temperature (Ref.
123201): 25.7 - 28.9, mean 27.5 °C (based on 467 cells).
Fylogenetische diversiteitsindex (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00756 - 0.03322), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
