Estimates based on models
Preferred temperature (Ref.
123201): 7.1 - 25.2, mean 19.7 °C (based on 61 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00049 (0.00027 - 0.00088), b=3.25 (3.09 - 3.41), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
