Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00543 - 0.02320), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.46 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (tmax=24).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (74 of 100).

Price category (Ref. 80766): Unknown.
