Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00434 - 0.02412), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.5 ±0.5 se; based on diet studies.
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
