Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00543 - 0.01275), b=3.08 (2.96 - 3.20), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.3 se; Based on diet studies.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (K=0.09-0.2; tmax=37; tm=3-7;).
Vulnerability (Ref. 59153):  High to very high vulnerability (70 of 100) .
