Estimates based on models

Preferred temperature (Ref. 115969): 1.2 - 6.9, mean 3.6 °C (based on 326 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7539   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00441 - 0.02728), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100) .
