Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00697 - 0.03603), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Vulnerability (Ref. 59153
): Moderate to high vulnerability (48 of 100) .
