Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5664 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00382 - 0.02499), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.8 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
