Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 13; Μαλακές ραχιαίες ακτίνες (συνολικά) : 14 - 16; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 7 - 9. Head spines weak - nasals present, preocular and parietal spines usually absent, supraocular, postocular, tympanic, coronal and nuchal spines absent (Ref. 27437). May have a prominent symphyseal knob; posterior edge of anal fin vertical (Ref. 27436). Caudal fin nearly truncate but slightly forked (Ref. 6885). Olive green to greenish brown with some light mottling dorsally, light ventrally; fins yellowish green, ventral fins often tinged in orange (Ref. 27436).
Body shape (shape guide): fusiform / normal.
Form schools in open water along steeply sloping shores or above rocky reefs; also holes up amid cracks and crevices of the sea floor (Ref. 27436). Juveniles found around floats and pilings (Ref. 27436). Feed on pelagic crustaceans, fishes and squids (Ref. 6885). Viviparous (Ref. 34817). Filleted, then sold fresh or frozen, with other rockfishes (Ref. 27436).
