Estimates based on models

Preferred temperature (Ref. 123201): 8.9 - 17.1, mean 11.7 °C (based on 175 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00014 (0.00007 - 0.00026), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.66 se; based on food items.
