The unicornfishes are tropical, herbivorous marine surgeonfishes in the genus Naso. They are so named because of a spike that protrudes from their foreheads. Some species have a bulbous protrusion rather than a pronounced spike, and some lack a spike altogether. Unicornfishes usually have a pair of spines on each side of the tail shaft that are used for defense.
