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=0.01122 (0.00397 - 0.03168), b=2.97 (2.73 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.1 ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
