Dorsal fin is like a sail, beginning above the eyes and extending to the tail stalk. The colouration is variable, yellow to dark brown, the face sometimes contrasting.
Brown specimens usually do not sit on high-contrast ground, but rather on dark sand or fine rubble. They are well camouflaged on such ground and from some distance they are easily mistaken for withered leaves.
Size : 15 cm
Habitat : Inhabits protected sand, mud and rubble, 1-80 m. Alone or in pairs. Sways sideways in order to imitate a dead leaf.
