Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 23.4 - 28, mean 26.5 (based on 298 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00091 (0.00045 - 0.00186), b=3.11 (2.94 - 3.28), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245
