Did you know?

  1. Bright colors and designs help butterflyfish disappear against the many colors of the reef.
  2. The threadfin butterflyfish changes color at night, developing splotches over parts of the body to mask its bright colors in the dark.
  3. When butterflyfish wear stripes and spots, predators can’t quite tell what shape and size it really is.
  4. Most butterflyfish have a dark stripe through their eye and an “eyespot” located towards their tail which helps confuse predators.
