Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.00634 - 0.03785), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Fishing Vulnerability (Ref.
