California scorpionfish or sculpin (Scorpaena guttata) are a “relatively heavy-bodied species, with strong head and fin spines, ranging in color from red to brown, often with purple blotches and always covered with dark spots…The sharp spines on the dorsal, anal and pelvic fins are poisonous…Scorpionfish are found from Santa Cruz, California south along the Pacific coast of Baja California and into the Gulf of California. Preferring warmer water, this species is common as far north as Santa Barbara…Scorpionfish are a carnivorous, ambush predator. Small crabs are probably the most important food of the scorpionfish. They are primarily nocturnal and feed at night. Octopi prey on small individuals” (Source: California Department of Fish and Game).
