Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 52 - 66; Duri dubur: 1; Sirip dubur lunak: 38 - 47; vertebrata, bertulang belakang: 34 - 37. Distinguished by the presence of both eyes on the same side of the head, dorsal and anal fins that are marked with dark and light (white to orange) bars, and especially, by the stellate, bony tubercles scattered over its body (Ref. 27547). Dorsal originates over middle of upper eye; anal with a sharp, forward pointing spine (often buried in skin) before first ray; pectorals are bluntly pointed; caudal slightly rounded (Ref. 27547). Eyed side dark brown to nearly black, sometimes with indefinite blotchings (Alaskans specimens sometimes with a greenish tinge); blind side white to creamy; dorsal fin with 4 to 7 dark bars with white to orange spaces between; anal fin with 4 to 6 such bars; caudal fin with 3 or 4 dark longitudinal bars on its posterior part; in rare cases, the blind side may be partly or completely colored like the eyed side, or white may be present on the eyed side, creating a piebald effect (Ref. 27547, 28897, 28898).
Body shape (shape guide): short and / or deep.
Found inshore, often in very shallow water and in estuaries during the summer; moving into deeper water in the winter (Ref. 27547). However, they may occur in deep water throughout the year (Ref. 27547). They do not venture into water of high salinities (Ref. 28899). Young and adults move up rivers, as much as 120 km (Ref. 27547). Benthic (Ref. 58426). They feed on crustaceans, worms, small mollusks, brittle stars, and small fishes (Ref. 6885). Important game fish (Ref. 2850). Utilized fresh and frozen; eaten steamed, fried, boiled, microwaved, and baked (Ref. 9988).
Onset of metamorphosis occurs at 10.5 mm. First settlement of young is in shallow silty-sandy substrates, usually in estuaries (Ref. 117245).
