Estimates based on models
Preferred temperature (Ref.
123201): 5.4 - 19.1, mean 17.2 °C (based on 50 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00636 - 0.01435), b=3.13 (3.01 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
