Taggstrålar i ryggfenan (totalt) : 21 - 22; Mjukstrålar i ryggfenan (totalt) : 24; Taggstrålar i analfenan: 1; Mjukstrålar i analfenan: 23 - 24. Caudal broadly rounded or truncate.
Body shape (shape guide): fusiform / normal.
Occurs in rocky inshore areas, common on kelp beds, also on sand bottoms (Ref. 2850). Feeds on crustaceans, polychaete worms, brittle stars, mollusks, and small fishes (Ref. 28499). Young are food of steelheads and salmon (Ref. 6885). Frequently caught by shore and skiff fishers and speared by divers (Ref. 2850).
