Identification[edit | edit source]

Similar to Naso elegans. The N.lituratus has a tall and oval-shaped body with a perfect triangle for a caudal fin. The base colour of the fish is beige with a black forehead and eyes. The dorsal and anal fins are black and dark yellow respectively. Its common name refers to the red around the lips. The other common name of "Unicorn" derives from the "horn" that some specimens develop on their foreheads.
The Naso has two very sharp, razor-like caudal spines on each side of the tail that are surrounded by a bright orange area, so extreme care should be used when handling this fish.
