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=0.00355 (0.00145 - 0.00871), b=3.06 (2.85 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).
