Max length : 51.0 cm SL maschio/sesso non determinato; (Ref. 3397); common length : 30.0 cm SL maschio/sesso non determinato; (Ref. 4781)
Spine dorsali (totale) : 11 - 12; Raggi dorsali molli (totale) : 14 - 17; Spine anali: 3; Raggi anali molli: 13 - 15. Black spot at the pectoral fin base. Body relatively slender with 10 golden longitudinal stripes (Ref. 35388).
Body shape (shape guide): fusiform / normal.
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).
