The black spot on the copperband butterflyfish’s (Chelmon rostratus) dorsal fin isn’t just for show, it’s actually a form of defense! How?

It’s a false eyespot, likely to confuse and deter predators from approaching. The fish uses its long snout to reach prey, like crustaceans and coral polyps, that are found in crevices and holes of coral reefs. It inhabits shallow tropical reefs in the Indo-Pacific.
