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=0.01202 (0.00462 - 0.03130), b=3.01 (2.79 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.8 ±0.26 se; based on food items.
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
