Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 24.5 - 29, mean 27.7 (based on 1138 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00289 - 0.01377), b=3.09 (2.90 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.1 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
