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.


Scorpaenichthys marmoratus becomes almost a meter long, making it the largest species of bullhead. It reaches a weight of 14 kg. The fish have absolutely no scales. The head looks beefy. There is a branched tuft of skin above each eye. The upper spine of the gill cover is rounded or slightly curved. There is a distinct fold of skin above the upper lip. Scorpaenichthys marmoratus is brown, yellowish, greenish or reddish on the back and whitish on the belly. The caudal fin is slightly rounded.

Fin formula: dorsal VIII-XII / 15–18, anal 0 / 11–13, ventral 5.

Way of life

Scorpaenichthys marmoratus lives in rocky habitats, in kelp forests and on sandy and muddy sea beds. It feeds on crustaceans , fish and mollusks . The fish gather in larger groups for reproduction.


Scorpaenichthys marmoratus is one of the few bull relatives that are of economic importance. The meat is considered good, but is often greenish-blue in color. The color disappears when cooked. The roe of Scorpaenichthys marmoratus contains dinogunelline and is therefore poisonous.
