Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 1.5 - 10.2, mean 2.5 (based on 14 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00341 - 0.01686), b=3.11 (2.92 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.6 ±0.4 se; Based on size and trophs of closest relatives
