Cabezon (Male)
Scorpaenichthys marmoratus

Physical Description

• Cabezon is from the Spanish for ‘large head,’ which is a main characteristic of these fish.
• Large, scaleless fish with a broad bony support extending from the eye across the cheek just under the skin.
• It has 11 spines on its dorsal (back) fin. Has a stout spine before the eye.
• Can reach 3 feet in length and 31 pounds in weight.
• Females (#67) are larger than the males.
• Males are red, with lots of mottling to help with camouflage.
• Their skin and mouth can look blue.

Range

• Native to the Pacific coast of North America.
• North Alaska to central Baja California, Mexico.

Habitat

• Live in rocky, muddy, and sandy bottoms, and kelp beds.
• Juvenile fish settle in intertidal pools before moving to rocky reefs and kelp forests.
• Found at depths of 0–656 ft.

Reproduction

• Adults spawn on rocky outcroppings in shallow water.
• Males guard the eggs until they hatch.
• The larvae drift in the plankton for 3-4 months before hiding in kelp mats as larval fish.
• The larval fish then settle in the intertidal zone as juvenile fish.

Diet

• Cabezon feed on crustaceans, mollusks, fish, and fish eggs.

Predators

• Larger fish, marine mammals.

Interesting Facts

• Cabezon spines, internal organs, and eggs are considered toxic to humans, but their meat can be consumed. It is blue, but will turn white when cooked.
• Unlike most fish, cabezons lack a swim bladder. Thus there is no damage to their tissues when they are brought up from deep pressure (depths) quickly.
• Cabezon are the largest sculpin species.
