Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 13; Μαλακές ραχιαίες ακτίνες (συνολικά) : 13 - 16; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 7 - 9; Σπόνδυλοι: 26. Head spines very weak - preoculars present, nasal, supraocular and parietal spines usually absent, postocular, tympanic, coronal and nuchal spines absent; chin projects outward; preopercular spines fairly strong; anal fin small and rear edge slanted posteriorly, 2nd anal spine short; body slender (Ref. 27437). Caudal fin moderately indented (Ref. 6885). Pinkish red to copper pink, white ventrally; lateral line in bright red zone; caudal fin dusky (Ref. 27437).
Adults frequent deep rocky reefs as well as sand and mud bottoms; young are pelagic (Ref. 36715) and occur in shallower waters (Ref. 2850). Feed on euphausiids (Ref. 6885), krill, small squids and fishes (Ref. 2850). Viviparous, with planktonic larvae (Ref. 36715). Marketed fresh and frozen; eaten fried, boiled, microwaved and baked (Ref. 9988).
