50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00333 - 0.01437), b=3.11 (2.93 - 3.29), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
营养阶层 (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
