Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00093 (0.00045 - 0.00194), b=3.10 (2.93 - 3.27), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.0 ±0.65 se; Based on food items.
Resilience (Ref. 69278
