Écologie
marin; saumâtre benthopélagique; océanodrome (Ref. 51243); profondeur 5 - 70 m (Ref. 3688). Subtropical; 45°N - 40°S, 26°W - 36°E

Length at first maturity / Taille / Poids / Âge
Maturity: Lm 16.5 range ? - ? cm
Max length : 51.0 cm SL mâle / non sexé; (Ref. 3397); common length : 30.0 cm SL mâle / non sexé; (Ref. 4781)
Épines dorsales (Total): 11 - 12; Rayons mous dorsaux (Total): 14-17; Épines anales 3; Rayons mous anaux: 13 - 15. Black spot at the pectoral fin base. Body relatively slender with 10 golden longitudinal stripes (Ref. 35388).
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.
