Bayesian length-weight: a=0.00741 (0.00278 - 0.01974), b=3.04 (2.80 - 3.28), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278

Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153
