Scott Haraguchi, a Hawaii fisherman, was attacked by a shark near the Kualoa shore in Honolulu, Hawaii, on May 12. He lives to tell the tale.

On May 12, Haraguchi was out fishing. He caught a fish but forgot to turn off his GoPro, which managed to record what happened next. Minutes later, a tiger shark attacked Haraguchi’s kayak, leaving him screaming in fear.

“I heard a whooshing sound that sounded like a boat heading towards me without the motor and I looked up and I saw this big brown thing. My brain thought it was a turtle, but then I got slammed by it, and realized that it was a tiger shark,” Haraguchi told ABC7.

He managed to gather courage and kick the shark away from his kayak.

Haraguchi got back home and realized that his GoPro had recorded the horrifying attack. He shared the video on YouTube.

In the caption, he wrote, “[It] happened so fast. [I] didn’t realize I took my left foot out of the water to brace myself from impact and actually pushed the shark’s head off with it.”

If you asked me to do that again, even without the shark, I don’t think I’d have that flexibility (sic),” he added.

Speaking to KITV4, the lucky-to-be-alive angler said he believes the shark may have mistaken his kayak for a seal.

“I’m thinking that the shark disabled and wounded the seal…and was waiting for it to die, came back and thought I was the seal, and attacked me instead,” he told the outlet.
