Estimates based on models
Preferred temperature (Ref.
123201): 23.4 - 29, mean 27.8 °C (based on 44 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00466 - 0.02049), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
