Bayesian length-weight: a=0.00832 (0.00546 - 0.01268), b=3.08 (2.96 - 3.20), based on LWR estimates for species & Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.6 ±0.1 se; Based on diet studies.
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (K=0.09-0.2; tmax=37; tm=3-7;).
Vulnerability (Ref. 59153
): High to very high vulnerability (70 of 100) .
