Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 26 - 27.6, mean 26.9 (based on 14 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00429 - 0.01769), b=3.07 (2.91 - 3.23), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.9 ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
