Description
The spotted rockfish is a scorpionfish (Scorpaenidae) from deeper rocky and reef water of the northwest Pacific. The species grows to about 30 cm and has a stocky, red-brown mottled body with pale spots and a large, spiny head. As a bottom-oriented ambush hunter it shelters among rocks and coral and snaps at small fish and crustaceans. It gives birth to live young. The dorsal and gill-cover spines are venomous and can give a painful puncture wound.
