Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01108 - 0.04738), b=2.95 (2.76 - 3.14), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.52 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K = 0.17).
Vulnerability (Ref. 59153):  High vulnerability (62 of 100) .
Price category (Ref. 80766):   Medium.
