Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 13.7 - 23.7, mean 17 (based on 61 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.1 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
