Bluecheek Butterflyfish Chaetodon semilarvatus

Butterflyfish provide testimony to the health of a coral reef. A wide variety and plentiful numbers of these brightly colored, disk-shaped fish indicate that a reef is flourishing. Bluecheek butterflyfish are usually seen in pairs and often hide under table corals. The blue eye-patch hides the eye and confuses predators.
