生物學特性     字彙 (例如 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 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

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.東大西洋與西印度洋: 在地中海與從各處,英國人使非洲到莫三比克南部與馬達加斯加的圓到最南端成為島嶼 (參考文獻 48610) 。 西南大西洋: 巴西東南方,烏拉圭與阿根廷。
