Scorpaenichthys marmoratus is a species of fish from the group of bull relatives (Cottales). It occurs close to the coast in the northeastern Pacific from Sitka on the coast of southeast Alaska to Punta Abrejos on the Mexican peninsula Baja California and lives from theintertidalzone to depths of about 70 meters. After it has long been assigned to the bullheads, it is placedin an independent, monotypical familyin the current systematics of bony fish , the Scorpaenichthyidae.
