Estimates of some properties based on models

Preferred temperature (Ref. 115969): 26.1 - 28.9, mean 27.8 (based on 532 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.01023 - 0.02570), b=2.99 (2.86 - 3.12), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
