Feeds on crabs, mollusks, octopus, fishes, and other reef prey captured with a large ambush mouth.
Cabezon is part of the nearshore groundfish framework with species-specific bag, season, depth, area, and fillet provisions. Verify current rules before retention.

Handling & release
Use tackle strong enough to land the fish without an exhausting fight, and keep a dehooker or suitable release tool ready.
If releasing, dehook in the water when possible. Never gaff a fish you plan to release, keep air exposure brief, wet your hands, avoid eyes and gills, and support the body rather than hanging the fish by its mouth.
Face a sluggish fish into the current until it can swim away under its own power.
