Environment / Climate / Range
Ecology
Marine; brackish; benthopelagic; oceanodromous (Ref. 51243); depth range 5 - 70 m (Ref. 3688). Subtropical, preferred 25°C (Ref. 107945); 45°N - 40°S, 26°W - 36°E
Eastern Atlantic: Bay of Biscay and Strait of Gibraltar to Sierra Leone, including Madeira, the Canary Islands, and Cape Verde; Congo to South Africa. Also present in the Mediterranean.
Length at first maturity / Size / Weight / Age
Maturity: Lm 16.5  range ? - ? cm
Max length : 51.0 cm SL male/unsexed; (Ref. 3397); common length : 30.0 cm SL male/unsexed; (Ref. 4781)
Found over rocky substrates and sandy area with algal growth. Gregarious, sometimes forming sizeable schools. Young mainly carnivorous on crustaceans, adults almost exclusively herbivorous (Ref. 4781), feed on seaweeds (Ref. 36731). Protandric hermaphrodite (Ref. 4781). Tasty when fresh, but easily softens and is not much esteemed (Ref. 3198).
A monandric species (Ref. 55367). Sex change occurs at 25.0 cm TL and 3.75 years of age (Ref. 55367). Conflicting descriptions of the reproductive style of this species have been reported, including possible gonochorism (Ref. 103751). Also Ref. 28504.
