Preferred temperature (Ref. 115969
): 3.6 - 8.3, mean 5.5 (based on 51 cells).
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00305 - 0.03131), b=3.03 (2.77 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
