Yes, looks like a staghorn sculpin. (although there are also many other small sculpin).
Pacific Staghorn Sculpin
Species: Leptocottus armatus (Girard, 1854); from the Greek words
leptos (slender) and
cottus (a sculpin); and the Latin word
armatus (armed, referring to the strong antler-like preopercular spine).
Alternate Names: Commonly called bullhead; also smooth cabezon, buffalo sculpin, and smooth sculpin. Called charrasco de astas in Mexico.
Identification: Noted primarily by the strong spine that precedes the gill cover on each side, and a spot at the rear of the first dorsal fin. Their coloring is tan, brown, grayish, or greenish-brown above and white or yellow below.
Size: Up to 18.9 inches; most caught from piers are 6-8 inches long. The largest staghorn sculpin I caught was a fish nearly 16 inches long while fishing from the shore at Port Angeles , Washington (in the Strait of Juan de Fuca).
Range: Bahia San Quentin, Baja California, and Puenta Baja, northern Baja California, to Izembek Lagoon southeastern Bering Sea coast, Alaska, Port Moller and Pribilof Islands, Bering Sea. Common from Bahia San Quintin, northern Baja California, to the Pribilof Islands.
Habitat: Typically found in nearshore shallow waters, both oceanfront and in bays and estuaries. Found intertidally to a recorded depth of 1,099 feet.
Piers: Virtually every pier in California with a sand or mud bottom seems to see this pesky little fish. I've caught “bullheads” from 60 piers in the state, from the Imperial Beach Pier, the most southern pier in the state (close to the Mexican border), to the most northern pier, the “B” Street Pier in Crescent City (which isn't too far away from Oregon). I’ve also caught them from the Mukilteo Pier and Golden Gardens Park Pier in Washington. Many times, at many piers, there have been times when I could hardly keep the bait stealers off my hooks. In California they are most common north of Pismo Beach. Probably more staghorn sculpin are caught from San Francisco Bay and Humboldt Bay piers than any other type of fish (although the numbers in San Francisco Bay seem to have seen a slight decrease recently).
Shoreline: Frequently caught by shore anglers fishing in bays.
Boats: An inshore species, rarely taken from boats.
Bait and Tackle: Will hit almost any bait although they especially like small pieces of pile worm or small strips of anchovy. They're usually caught on the bottom while fishing for other fish.
Food Value: Although some groups of anglers do keep them and fry them up like catfish, I've been told they have a rather bland taste. One book from Canada says that they’re most suitable for a “fish paste.” Since the thought of staghorn paste on Ritz crackers leaves me sort of numb, I’d throw ‘em back.
Comments: I rarely saw staghorn sculpins caught at any southern California pier during the 1960s and 1970s. However, during the ‘80s I saw an increasing number of the little critters grabbing SoCal baits. I don't know why, I'm just reporting what I saw. “Bullheads” make excellent bait for striped bass in the San Francisco Bay Area. With the exception of cabezon, the king of the family, most sculpins caught from California piers are small (if not tiny) and strictly incidental catches when fishing for other species. Nevertheless you've got to love this family of fish. What other family has fish with names like hookear, roughcheek, padded, scalyhead, smoothhead, bonehead, rosylip, roughback, sharpnose, mosshead, woolly, bald, spinyhead, bull, smoothcheek, armorhead, pit-head, thorny, eyeshade, snubnose, pored, spinynose, smoothgum, grunt and manacled sculpin? Sounds like some great names for mob members. And don’t forget my personal favorite—the blob sculpin—whose actual appearance is even more pathetic than its name. The family sounds like they deserve their own TV show on HBO.
