Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 10 - 12; Anal spines: 0; Anal soft rays: 10 - 12. Lower edge of preopercle projecting downward as a strong antrorse spine. Infraorbital and suborbital ridges bearing many fine serrations. Lower side of head unicarinate. Dorsal fin usually 11. Iris lappet bilobed. Caudal fin with a white basal band, a broad dusky submarginal band and a narrow white edge.

Benthic on sand and mud bottoms (Ref. 30573). Usually caught with trawls to depths of about 80 m (Ref 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 28.6, mean 27.5 °C (based on 655 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00230 - 0.00908), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.7 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
