Naso lituratus, also known as the clown unicornfish, orangespined unicornfish, orangespine unicornfish, black-finned unicornfish, Pacific orangespined unicornfish, blackfinned unicornfish or the stripefaced unicornfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, which includes the surgeonfishes, unicornfishes and tangs. It is native to the eastern Indian Ocean and western Pacific Ocean, where it is found in coral reefs, often in pairs. Naso lituratus is easily identified by two bright orange forward-hooked spines on the caudal peduncle (the tail base), as well as its orange lips and black face mask.
