50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
