Estimates based on models

Preferred temperature (Ref. 123201): -1.6 - 1.8, mean -0.6 °C (based on 2043 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00431 - 0.01274), b=3.25 (3.10 - 3.40), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on diet studies.
