Preferred temperature (Ref. 115969
): 3.3 - 7.1, mean 4.4 (based on 126 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00388 - 0.02580), b=3.04 (2.81 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.7 ±0.2 se; Based on size and trophs of closest relatives
