50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00310 - 0.01545), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
回复力 (Ref.
