Estimates based on models
Phylogenetic diversity index (Acuan
82804): PD
50 = 0.5703 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00178 - 0.01174), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Acuan
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low vulnerability (13 of 100).
