Butterflyfish, with their amazing array of colors and patterns, are among the most common sites on reefs throughout the world.
Although some species are dull-colored, most wear intricate patterns with striking backgrounds of blue, red, orange, or yellow. Many have dark bands across their eyes and round, eye-like dots on their flanks to confuse predators as to which end to strike and in which direction they're likely to flee.
There are about 114 species of butterflyfish. They have thin, disk-shaped bodies that closely resemble their equally recognizable cousins, the angelfish. They spend their days tirelessly pecking at coral and rock formations with their long, thin snouts in search of coral polyps, worms, and other small invertebrates.
Some butterflyfish species travel in small schools, although many are solitary until they find a partner, with whom they may mate for life.
