50 = 0.5664 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00213 - 0.01418), b=3.16 (2.94 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 2.8 ±0.20 se; based on food items.
Fishing Vulnerability (Ref.
