50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00707 - 0.03555), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
營養階層 (Ref.
69278): 2.0 ±0.00 se; based on food items.
Generation time: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
