Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 13; Μαλακές ραχιαίες ακτίνες (συνολικά) : 13 - 15; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 7. Head spines moderate to weak - nasal, preocular, supraocular, postocular, tympanic and parietal spines present, nuchals usually absent, coronals absent (Ref. 27437). Lower jaw rough and scaly; caudal peduncle deep (Ref. 27437). Caudal fin slightly indented (Ref. 6885). Dark red in color, sides mottled with gray; mouth and fins red, fins usually edged with black; 3 obscure stripes radiating from each eye (Ref. 27437).
Adults inhabit shallow to deep rocky reefs, less common on deep ones (Ref. 2850). Young inhabit shallow water (Ref. 2850). Viviparous (Ref. 34817). Sold as fillets together with other rockfish (Ref. 27436). Maximum depth and minimum common depth from Ref. 128668.

Estimates based on models
Preferred temperature (Ref.
123201): 6.4 - 9.9, mean 6.9 °C (based on 16 cells).
Phylogenetic diversity index (Ref.
