Biologie     Glossaire (ex. epibenthic)

Adults prefer rocky bottoms (Ref. 5222), are solitary and territorial (Ref. 12382). Juveniles are found closer to shore (Ref. 48605) in rocky tidal pools (Ref. 48609). Enters brackish environments (Ref. 57293). Mainly feed on crabs and octopi; larger individuals feed on a greater proportion of fishes, the majority of which are reef-associated species (Ref. 6842). A protogynous hermaphrodite (Ref. 55367). Mature individuals form spawning aggregations (Ref. 55367). Utilized as a food fish (Ref. 171). Readily caught by anglers (Ref. 5222). Not adapted well in an aquarium (Ref. 12382).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves

A monandric species (Ref. 55367). In Europe, sex reversal occurs when females are about 14-17 years of age and between 80 to 90 cm TL (Ref. 51466). From another study, sex change occurs at 88 cm TL and 12 years of age (Ref. 55367), between 52-77 cm TL and 7-17 years (Ref. 94520). Protogynous hermaphrodite species, reaching its first sexual maturity as female at 5 years and becoming male after 10 years (some females remain so for some more years). Spawning happens during summer.
