If you’ve ever watched a humpback whale swim, you may have seen it launch most of its body out of the water and splash back into the ocean on its side or back. This behavior is called breaching, and scientists don't know exactly why the whales do it. Researchers have theorized that breaching might signal competition between males, serve as a warning to perceived threats, or stun the whale's prey for easier eating. A recent study suggested that the dramatic displays could be a method of long-distance communication.

Rarely are nature lovers lucky enough to glimpse a whale breaching completely out of the water. But in the video below—spotted by Bored Panda and filmed by scuba diver Craig Capehart off the coast of Mbotyi in southeastern South Africa—you can watch an adult humpback whale soar through the air, with its entire body and tail completely exposed.
