Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 11 - 14; Spine anali: 3; Raggi anali molli: 5 - 8; Vertebre: 26. Head spines strong - nasal, preocular, postocular, tympanic and parietal spines present, supraocular, coronal and nuchal spines absent (Ref. 27437). Toothed knob in front of each upper jaw, deep notch between jaws (Ref. 27437). Caudal fin moderately indented (Ref. 6885). A red rockfish, silver ventrally (Ref. 27437). Branchiostegal rays: 7 (Ref. 36715).
Body shape (shape guide): fusiform / normal.
Common offshore, on soft bottoms (Ref. 2850). Young occur in shallow water, often at surface under drifting kelp (Ref. 2850). Viviparous, with planktonic larvae and pelagic juveniles (Ref. 36715, 34817). The biggest individuals are sometimes found in markets where the flesh is sold as rockfish fillet (Ref. 27436). Rarely caught by anglers (Ref. 27436).)
Gives birth in spring (Ref. 27436).
