Estimates based on models
Preferred temperature (Ref.
123201): 24.9 - 29.3, mean 28.2 °C (based on 900 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01098 - 0.05004), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
