Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02188 (0.00867 - 0.05518), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 2.0 ±0.00 se; based on food items.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (39 of 100).

Categoria de preço (Ref. 80766): Unknown.
