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=0.01000 (0.00529 - 0.01890), b=3.02 (2.86 - 3.18), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.8 ±0.6 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.21-0.61).

Vulnerability (Ref. 59153): Low to moderate vulnerability (27 of 100) .

Price category (Ref. 80766): Very high.
