50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00479 - 0.01378), b=3.06 (2.92 - 3.20), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
營養階層 (Ref.
69278): 4.2 ±0.63 se; based on food items.
Generation time: 6.4 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
