"Banded Butterflyfish," Wikipedia, the free encyclopedia. The banded butterflyfish (Chaetodon striatus) is a butterflyfish found in the western Atlantic Ocean from Brazil to Bermuda. The name is derived from the dark vertical bands on the fish's body. This, combined with a vertical, black bar through the eye, is designed to confuse predators.
