Found mostly near the reefs of the Atlantic, Indian, and Pacific Oceans, butterflyfish are named for their brightly colored and strikingly patterned bodies. Seen in shades of black, white, blue, red, orange, and yellow, many have eyespots on their flanks and dark bands across their eyes that resemble the patterns on butterfly wings, making them popular additions to aquaria. Because butterflyfish are easily spotted among reefs, some believe their conspicuous coloration serves what purpose? Discuss
