Estimates based on models

Preferred temperature (Ref. 115969): 7.4 - 15.6, mean 12.3 (based on 83 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6289   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00288 (0.00111 - 0.00747), b=3.14 (2.92 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.70 se; Based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Assuming Fec <100).
Vulnerability (Ref. 59153):  High to very high vulnerability (68 of 100) .
