Estimates based on models
Phylogenetic diversity index (Acuan
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00424 - 0.02252), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Acuan
69278): 3.5 ±0.5 se; based on diet studies.
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
