5. Tarpon (Megalops atlanticus)

In the Gulf of Mexico, the Caribbean, and Florida’s coastal waters, tarpon fish can be found swimming. These silvery fish are especially special because they use an intriguing method known as air-breathing. Tarpon use their mouths to take in large amounts of air when they leap out of the water in order to get oxygen. They might therefore be able to breathe underwater.

In addition, tarpon fish use their large eyes for ultraviolet vision to identify predators and prey with skin that reflects light.
