Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  4.3   ±0.8 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100) .
Price category (Ref. 80766):   Unknown.
