Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00071 (0.00031 - 0.00164), b=3.12 (2.92 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100).
