Estimates based on models
Preferred temperature (Ref.
123201): 7.1 - 13.9, mean 9.5 °C (based on 83 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00145 (0.00087 - 0.00240), b=3.20 (3.05 - 3.35), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
