Estimates based on models
Preferred temperature (Ref.
123201): 8.2 - 9.7, mean 9.2 °C (based on 32 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5703 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
