Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00978 (-0.20103 - 0.22059), b=2.98 (2.86 - 3.10), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.6 ±0.6 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years ().

Vulnerability (Ref. 59153): Very high vulnerability (76 of 100) .

Price category (Ref. 80766): .
