"Did you see that?"
Raw video: White shark's surprise breach caught on camera off the coast of Wellfleet, Massachusetts.
Sharks are about to get their biggest big screen make-over since Steven Spielberg's Jaws came to the screens 43 years ago.
According to the Boston Globe, the video shows biologist Greg Skomal standing on the pulpit of a research boat.
Shark breaching has been observed in Cape waters before, but usually in conjunction with feeding.
Yet the sight of a 2,000lb great white shark breaching remains one of the holy grails of both scientific and nature watching.
Video uploaded to YouTube by the Atlantic White Shark Conservancy shows the researcher on a boat earlier this week in waters off the U.S. state of MA.
"While encounters like this one are rare, this video shows that they're certainly possible", said the conservancy's post. Just after the pilot says the shark is "right off your bow", the predator leaps toward Skomal.
Unbelievable footage shows a scientist's dangerously close encounter with a 12-foot great white shark.
Great white sharks can get up to 20 feet long, and have powerful tails that enable them to swim up to 15 miles per hour and breach the water during an attack, says National Geographic.
The group called it a good reminder of the importance of not becoming complacent and always staying vigilant when in or on the water.
