Description

The giant kelpfish is a kelpfish (Clinidae) from the eastern Pacific off the west coast of North America. The species has an elongate, laterally compressed body with a pointed snout and a strongly variable colour (green, brown or reddish) that mimics the colour of the surrounding weed, an excellent camouflage. It lives among rocks with large seaweeds, often in kelp forests, from the intertidal zone to about 40 m deep. As an ambush hunter it springs on small crustaceans and small fishes. The species is harmless to humans.
