Man captures dramatic moment when shark attacked him

A diver's dramatic encounter with a shark was captured on video as he was spearfishing in Fiji. In a video that Henry Gibbs posted on social media, a grey reef shark can be seen making semicircles below the surface before surging toward him and attacking on July 19. Gibbs, a New Zealand-based ocean enthusiast and content creator, said the shark latched onto his calf and began "death rolling." "Feeling incredibly lucky to still have my leg, full use of my foot and to be on the mend, Gibbs wrote in a social media post. "Four surgeries and a skin graft later, it's looking like I'll make a full recovery, which I’m hugely grateful for," Gibbs added. Gibbs said there were a handful of grey reef sharks in the water at the time. "I never thought a shark of that size posed much of a threat, and that was a mistake," he said. All in all, he said he hopes others learn from his mistake that could've been much more serious. "No hard feelings towards the shark. I was in its environment hunting its food. Wrong place, wrong time," he said. "And there are definitely a few lessons I’ll share when I post the footage in the hope it helps someone avoid ending up in the same situation and a bit on how to respond to it."
