Estimates based on models
Preferred temperature (Ref.
123201): 11.2 - 18, mean 14.4 °C (based on 327 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00801 - 0.01038), b=2.98 (2.94 - 3.02), in cm total length, based on LWR estimates for this species (Ref.
