A scuba diver from San Diego survived a too-close encounter with an “immense” great white shark that chomped down on his kayak — leaving behind a pair of 2-inch long teeth.

Danny McDaniel was in the ocean with a friend Saturday off California’s Catalina Island southwest of Los Angeles when something bumped into his kayak. McDaniel assumed it was his buddy, but realized within seconds that the pair weren’t alone, he told the Los Angeles Times.

“I saw the snout of the shark over the back of the kayak,” McDaniel recalled. “Then I followed the snout up and there’s a giant, immense body off to the right side of the boat.”

With his friend about 25 feet away, shouting for McDaniel to hit the shark on its head, he quickly realized he was on his own. Luckily for McDaniel, the shark – estimated to be up to 19 feet long – decided to take an exploratory bite before swimming away and leaving behind two sizable teeth.

“I don’t think he took a full chomp,” McDaniel told KGTV. “I think he just took a nibble and pushed.”

The behemoth sea creature then pushed McDaniel’s kayak with enough force to rotate the vessel 180 degrees, likely causing its teeth to fall off, the Times reports.

The encounter sent McDaniel’s heart rate skyrocketing, according to data on his fitness tracker, but he was otherwise unharmed by the largest shark he’s ever encountered throughout more than 20 years of scuba diving.

Both McDaniel and his diving buddy, Jon Chambers, said they were “literally frozen” with fear for several moments after the experience, making sure to keep their paddles out of the water so the shark wouldn’t return, KGTV reports.

But three hours later, McDaniel and Chambers returned to the area for a night dive, which went off without a hitch or a shark sighting, they said.

“It’s one for the books, not something you want to replicate,” Chambers told KGTV. “He had the best shark attack experience without it being a bad story.”
