Estimates based on models

Preferred temperature (Ref. 123201): 4.8 - 15.3, mean 7.9 °C (based on 504 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00436 - 0.02294), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
