Estimates based on models
Preferred temperature (Ref.
123201): 25.2 - 28.9, mean 27.7 °C (based on 166 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00650 - 0.03213), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
