50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00335 - 0.01134), b=3.17 (3.00 - 3.34), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
