50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00338 - 0.01626), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.6 ±0.6 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
