Etymology: Sebastes: Greek, sebastes = august, venerable (Ref. 45335);  mystinus: Name from the Latinized form of the Greek word μυ;stησ, mwhich means initiated one or mystic, c, interpreted by some as 'priest'; 19th century fishermen of Monterey, CA called the fish 'pêche prêtre' because of its dark coloration and its light band between the head bars that resembles a clerical collar (Ref. 103574).

Biología     Glosario (por ej. epibenthic)

May be found near the surface or off the bottom, generally over shallow reefs, but also around kelp and over deep reefs (Ref. 2850). Juveniles are pelagic (Ref. 36715). Form schools, sometimes with other rockfishes (Ref. 2850). Feed mainly on krill (Ref. 2850), but also on tunicates, jellyfishes and fishes (Ref. 6885). Viviparous, with planktonic larvae (Ref. 36715). Young are important prey for fishes and other marine vertebrates (Ref. 2850).
