Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00415 - 0.01826), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 2.6 ±0.26 se; based on food items.
Resilience (Ref.

Fishing Vulnerability (Ref.
