Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00352 - 0.01079), b=3.21 (3.06 - 3.36), based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.3 se; Based on diet studies.
Resilience (Ref. 69278
