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=0.01738 (0.01011 - 0.02987), b=3.11 (2.96 - 3.26), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 2.5 ±0.22 se; Based on food items.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (tm=7; tmax=28).

Vulnerability (Ref. 59153): High to very high vulnerability (66 of 100) .

Price category (Ref. 80766): Unknown.
