Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 3.6 - 11.6, mean 6.2 (based on 2064 cells).
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.6 ±0.8 se; Based on size and trophs of closest relatives
