Meet the cabezon

Cabezon means “large head” in Spanish, and this sculpin gulps some good-sized prey. An indiscriminate predator, a cabezon will eat whatever fits in its mouth.

Natural history

A cabezon’s life cycle takes it offshore and back. An adult spawns on rocky outcrops, and the male guards the eggs until they hatch. The larval young drift out to sea, then develop into small, silvery fish that often hide under mats of drifting kelp. As a cabezon grows older, it settles into tide pools, then moves to reefs and kelp forests.

Conservation

This fish is easily caught while the male sits on its nest. Cabezon make up a large component of the shallow water rockfish fishery. Unless properly regulated, this species can easily become overfished.

Cool facts

  • The eggs of a cabezon are poisonous to humans and many other mammals and birds.
  • This is the largest member of the sculpin family in the Monterey Bay area.
