Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00610 (-0.22499 - 0.23719), b=3.07526 (2.95225 - 3.19827), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.5 ±0.5 se; Based on diet studies.

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): High to very high vulnerability (70 of 100) .

Price category (Ref. 80766): Unknown.
