Gene Mace captured the moment a kayaker was attacked by a great white shark in Monterey Bay, California, on March 18.

Gene Mace and his wife were out in Monterey Bay when he noticed a man had been flipped from his kayak. Mace took out his camera and saw that the man was under attack by a great white shark. Mace continues to capture the attack as he tells his wife to call for help. His wife can be heard speaking to authorities over the phone. The couple watches helplessly as the kayaker tries to swim away from the great white.

After a few minutes, a boat approaches the kayaker and a man, Lt. Cmdr. Kyle Franklin, can be seen trying to help the kayaker up to the small sailboat. Franklin was out sailing with his wife and daughter when he saw the kayaker frantically swimming away from the shark.

The video cuts off when Franklin approaches the kayaker, but a 29-foot Coast Guard Response Boat, stationed in Monterey Harbor, later arrived to rescue the kayaker, who was too tired and cold to get on the vessel on his own. Credit: Gene Mace Jr via Storyful
