Bayesian length-weight: a=0.00851 (0.00355 - 0.02043), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
