Foureye Butterflyfish

The foureye gets its name from the large, dark spot on the rear portion of the body, surrounded by a brilliant white ring. This spot acts as a false eye. A black, vertical bar on the head runs down the true eye, making it less visible. This may result in a predator confusing the rear end of the fish for the front end. The adult foureye has a white body marked with numerous dark, thin lines that radiate diagonally from the mid body to the top and the bottom of the fish. It is the only butterfly species in the area with these converging lines along the side of the body.
