Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 13.4 - 25.3, mean 17.1 (based on 199 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00378 - 0.02301), b=3.09 (2.88 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.3 se; Based on size and trophs of closest relatives
