Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 0.7 - 17, mean 2.1 (based on 206 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00453 - 0.01836), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.2 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
