Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11 - 12; Dorsal soft rays (total): 10 - 11; Anal spines: 3; Anal soft rays: 8. Body and fins reddish; anal fin and lower part of caudal fin edged with white.

Biology     Glossary (e.g. epibenthic)

Inhabit rocky or sandy bottoms; individuals descending to greater depths with growth. The stocks migrate seasonally between the coast and deeper waters in accordance with local hydrographic conditions and their life cycle. Feed mainly on fish and crustaceans; the young on plankton (Ref. 3688). Gonochorists (Ref. 4781).
