Estimates based on models

Preferred temperature (Ref. 123201): 9.7 - 25.7, mean 18.8 °C (based on 210 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5352 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00427 (0.00160 - 0.01136), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.7 se; based on size and trophs of closest relatives

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