Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 13 - 15; Spine anali: 3; Raggi anali molli: 6 - 7. Head spines weak - nasal, preocular, postocular, tympanic and parietal spines present, supraocular, coronal and nuchal spines absent (Ref. 27437). Notch on dorsal fin shallow; 2nd anal fin spine is of the same length or shorter than the 3rd (Ref. 27437). Caudal fin moderately indented (Ref. 6885). Light red and mottled with olive on back, lower sides flushed with yellow; light red stripe along lateral line; lips blackened; fins red with some light green or yellow (Ref. 27437).
Body shape (shape guide): fusiform / normal.
Occur in areas where rocky reefs and steep silt-covered cliff faces meet gently sloping sand or mud bottoms (Ref. 27436). Found hovering just off the bottom or resting on a rocky perch (Ref. 27436). Viviparous (Ref. 34817). Sold as fresh or frozen fillets, together with other rockfish species (Ref. 27436). Not popular as a game fish (Ref. 27436).
