Colour: Usually bright green with lateral stripes, but may be brown, yellow or mottled.
Habitat and Biology: Typically found in seagrasses or dense beds of algae at depths to 10 m. Mostly solitary in habit. Feeds chiefly on molluscs, hermit crabs, crabs, sea urchins and shrimps. Distribution: Indo-Pacific.
Remarks: The garish green colouration of Cheilio inermis helps it to camouflages within the seagrass beds. Because of this it is normally only spotted by careful observers, even though it is quite common.
