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=0.01175 (0.00560 - 0.02463), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.2 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.38-0.46).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).
