Estimates based on models
Preferred temperature (Ref.
123201): 24.4 - 28, mean 26.9 °C (based on 60 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5059 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00230 - 0.01199), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
