Bayesian length-weight: a=0.00891 (0.00416 - 0.01911), b=3.08 (2.92 - 3.24), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.42 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.3).
Vulnerability (Ref. 59153):  Moderate vulnerability (36 of 100) .
