Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01288 (0.00411 - 0.04035), b=3.03 (2.78 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.41 se; based on food items.

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