Preferred temperature (Ref. 115969
): 2.7 - 8.1, mean 4.2 (based on 1353 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5645 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00093 (0.00035 - 0.00246), b=3.05 (2.82 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.4 se; Based on size and trophs of closest relatives
