Estimates based on models

Preferred temperature (Ref. 123201): 4.1 - 8.6, mean 5.8 °C (based on 200 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00604 - 0.01816), b=3.05 (2.90 - 3.20), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.5 se; based on size and trophs of closest relatives
