Estimates based on models
Preferred temperature (Ref.
123201): 25.8 - 29.3, mean 28.6 °C (based on 1445 cells).
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00394 - 0.02313), b=2.96 (2.75 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
