Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.4 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).

Vulnerability (Ref. 59153): Low vulnerability (12 of 100) .
