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=0.00324 (0.00157 - 0.00666), b=3.11 (2.93 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.9 ±0.4 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).

Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100) .
