Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00263 (0.00101 - 0.00685), b=3.05 (2.82 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (53 of 100).
