Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 12; Anal spines: 3; Anal soft rays: 9. Head blunt. Interorbital space flat. Eye large. Preorbital bone relatively narrow. Snout short. Lower jaw protruding. Pectoral fins short, not reaching level of anus. Lower lobe of caudal fin with some rays excessively produced and filamentous in young. Scale rows on back parallel to lateral line. Overall color rosy red with a yellowish tinge; the dorsal fin grayish, the outer edge of its spinous portion black; the outer edge of the pelvic fins also black.

Adults are found on rocky bottoms in relatively deep water (Ref. 55). Marketed fresh (Ref. 55).

Estimates based on models

Preferred temperature (Ref. 123201): 13.3 - 23.4, mean 19.3 °C (based on 11 cells).

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

Bayesian length-weight: a=0.01549 (0.00716 - 0.03351), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.4 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 (44 of 100).

Price category (Ref. 80766): Very high.
