Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01838 (-0.19934 - 0.23611), b=3.00088 (2.88276 - 3.11900), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.3 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (31 of 100) .

Price category (Ref. 80766): Unknown.
