Estimates of some properties based on models
Preferred temperature (Ref.
115969): 20.6 - 27.7, mean 23.3 (based on 42 cells).
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00393 - 0.02432), b=3.08 (2.86 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
