Scorpion Fish, a family of marine fish. Scorpion fish are named for the venomous spines on their fins. They have large heads covered with ridges and spines. In most species, the skin is brightly colored and mottled to blend in with the ocean bottom, where they dwell. Scorpion fish have teeth, and feed primarily on shrimp and other crustaceans. They are a valuable food fish in North America. The commercially most important species are the Pacific ocean perch, found along the coast of California, and the redfish, found along the Atlantic coast. Many Pacific species are known as rockfishes because they inhabit rocky crevices.

Scorpion fish make up the family Scorpaenidae. The Pacific ocean perch is Sebastes alutus; the redfish, S. marinus.
