Fin's Fish Guide
The Common rockfish (Sebastiscus marmoratus) is a saltwater fish of the family Sebastidae that grows up to 36 cm.
Description
The false kelpfish is a scorpionfish (Scorpaenidae) from the northwestern Pacific. The species has a stocky body with a marbled brown-red pattern that camouflages it among rock and weed. It lives near shore on rocky bottoms and is commercially cultured in Japan. It is viviparous. As an ambush hunter it feeds on small fishes and crustaceans. The dorsal, pelvic and anal fin spines bear venom glands and give a painful puncture wound; treat a sting with hot water.
