Estimates of some properties based on models

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

Bayesian length-weight: a=0.00617 (0.00386 - 0.00986), b=3.12 (2.98 - 3.26), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.7 ±0.4 se; Based on diet studies.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (22 of 100) .

Price category (Ref. 80766): Very high.
