Estimates of some properties based on models

Preferred temperature (Ref. 115969): -1.8 - 0.9, mean -0.9 (based on 584 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00301 - 0.01384), b=3.19 (3.01 - 3.37), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.2 se; Based on diet studies.
