Moorish Idol Zanclus Cornutus Royalty-Free Stock Photography

The Moorish Idol has a very long, white, sickle-shaped dorsal fin, two broad black bars on the body, and a yellow saddle across the snout. There is a small, bony projection in front of both eyes of adults. The projections are larger in males. The genus name Zanclus comes from the Greek word for `sickle` and refers to the sickle-shaped dorsal fin. The species name cornutus is from the Latin word for `horn`, and presumably refers to the bumps over the eyes of adults.
