Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00362 - 0.01664), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.37 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
