Four-eyed butterflyfish


The “false eye” on the flanks of this fish is much larger than the real one in its head. This is a classic example of a distraction pattern which misleads predators into aiming for the rear of the fish, rather than its head. Similar eye-like spots are seen in other fishes and many insects. This is an abundant species in the Caribbean and the Southern Gulf of Mexico. In the summer, young specimens drift up the Atlantic coast with plankton, as far north as New England. This species has been popular in public aquariums for more than a hundred years.
