50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02188 (0.00867 - 0.05518), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
