Maturity: Lm 18.1  range ? - 22.5 cm
Max length : 50.0 cm TL con đực/không giới tính; (Ref. 3507); common length : 32.0 cm TL con đực/không giới tính; (Ref. 3507); Khối lượng cực đại được công bố: 4.2 kg (Ref. 3670)
Các tia vây lưng cứng (tổng cộng) : 11 - 12; Các vây lưng mềm (tổng cộng) : 10 - 11; Tia cứng vây hậu môn: 3; Tia mềm vây hậu môn: 7 - 9. Usually reddish orange in color, but sometimes blue with a white patch on the side (Ref. 3198).
Occurs above rocky bottoms in deeper water to 100 m but often caught from shore. Juveniles occur in shallow-water beds of seaweed where they feed on minute crustacean (Ref. 3670). Feeds on mollusks, crustaceans, worms and fish. Females transform into territorial males with growth (Ref. 3198). Voracious but sluggish, takes any bait. Good food fish (Ref. 3198). Sold fresh (Ref. 3507). It is parasitised by the monogenean Anoplodiscus cirrusspiralis on the fins and body surface (Ref. 124057).
