Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5664 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00178 - 0.01174), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.8 ±0.20 se; based on food items.
Fishing Vulnerability (Ref.
59153): Low vulnerability (21 of 100).
