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=0.00933 (0.00619 - 0.01407), b=3.11 (2.98 - 3.24), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 3.8 ±0.2 se; Based on diet studies.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (tm=6-8; tmax=9-13; K=0.08-0.21; Fec=2,00-10,000).

Vulnerability (Ref. 59153): High to very high vulnerability (68 of 100) .

Price category (Ref. 80766): Very high.
