Estimates based on models
Preferred temperature (Ref.
123201): 17.7 - 23.7, mean 21.8 °C (based on 59 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00052 (0.00033 - 0.00085), b=3.24 (3.11 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
