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=0.00457 (0.00217 - 0.00962), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): High vulnerability (59 of 100).
