Great White Sharks Surround Paddle Boarders

In this video filmed in Southern California, two paddleboarders came across what some people would describe as their worst nightmare. They were keeping company with a group of Great White sharks.

National Geographic says: "Shot on June 26 at Sunset Beach in Orange County, the video was made by Courtney Hemerick and Joseph Truckles, who remained calm through the experience."

"The 7-foot (2-meter) long sharks are juvenile great whites, which often congregate in protected bays and right off the surf zone along both U.S. coasts, particularly in California. The juveniles eat mostly fish, though they sometimes scavenge dead carcasses. When they grow up they become top predators, reaching sizes of up to 20 feet (6 meters) long and weights of up to 5,000 pounds (2,268 kilograms). The adult fish dine on other sharks, seals, dolphins, and whatever else they can catch."
