Estimates based on models
Preferred temperature (Ref.
123201): 9.1 - 18.7, mean 12.6 °C (based on 363 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00430 - 0.01608), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for species & Subfamily-BS (Ref.
