Estimates based on models
Preferred temperature (Ref.
123201): 16.7 - 24.2, mean 22.3 °C (based on 110 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00538 - 0.01619), b=3.09 (2.94 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
