Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 13; Μαλακές ραχιαίες ακτίνες (συνολικά) : 13 - 14; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 6 - 8. Head spines strong - nasal, preocular, postocular, tympanic and parietal spines present, supraocular, coronal and nuchal spines absent (Ref. 27437). Parietal ridges very high and thick (Ref. 27437). Mouth small (Ref. 27437). Caudal fin rounded (Ref. 27437). Body blue or black, mottled with yellow; some individuals white ventrally; a broad yellow stripe from about the 3rd dorsal spine runs into or along the lateral line (Ref. 27437). Pelvic, anal and caudal fins are dark (Ref. 27437).
A territorial species occurring on the open coast, among rocks and reefs (Ref. 2850). Has mildly venomous spines (Ref. 27436). Viviparous (Ref. 34817). One of the tastiest rockfishes (Ref. 2850) but rarely found in markets because it is rarely caught (Ref. 27436).
