Short description Morfología | Morfometría

Espinas dorsales (total): 13; Radios blandos dorsales (total): 11-14; Espinas anales 3; Radios blandos anales: 5 - 8; Vértebra: 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).

Biología     Glosario (por ej. epibenthic)

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).)

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
