Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01088 (-0.12892 - 0.15068), b=2.98 (2.90 - 3.07), based on LWR estimates for species & genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.62 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.50; Fec=389).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (25 of 100) .
Price category (Ref. 80766):   Unknown.
