Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00484 (-0.19250 - 0.20217), b=3.12985 (3.02526 - 3.23443), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 4.1 ±0.5 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Vulnerability (Ref. 59153): High vulnerability (59 of 100) .

Price category (Ref. 80766): Unknown.
