Estimates based on models
Preferred temperature (Ref. 115969
): 4.7 - 9.7, mean 6.1 (based on 212 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00305 - 0.01366), b=3.19 (3.01 - 3.37), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.6 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 120179
