Estimates based on models
Preferred temperature (Ref.
123201): 23.7 - 29, mean 27.3 °C (based on 1120 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00394 - 0.01927), b=2.78 (2.60 - 2.96), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
