  • Found at depths of 0–656 ft


  • 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

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.
