Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00475 - 0.03188), b=3.01 (2.79 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 2.0 ±0.1 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
