Foureye Butterflyfish GALLERYChaetodon capistratus
The Foureye Butterflyfish get's it's name from the four eyes it's markings display. One real eye and one "false" eye on the rear of it's body. Perhaps it's to confuse a would be predator. If a predator's instinct is to strike at the front of the prey, the Foureye Butterflyfish's rear EYE fools the predator to strike from behind by mistake and the Butterflyfish makes his escape. As Juveniles they start out with six eyes, an extra spot on the rear of the dorsal fin that fades with age. Like most Butterflyfish, you generally see them in pairs. You can find the very small juveniles in water as shallow as two feet. They range in size from one inch to six inches.
