Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00331 - 0.02635), b=3.02 (2.77 - 3.27), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.4   ±0.80 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Fec=4-10).
Vulnerability (Ref. 59153):  High vulnerability (65 of 100) .
Price category (Ref. 80766):   Medium.
