This would have been an incredibly intense experience, and thankfully no one was hurt. Great white sharks are said to be the world's largest predatory fish.
The captain of the boat, Carter Bates, spoke to the American media NBC Miami about this shark encounter and how truly harrowing yet incredible it was.
When he is there, near you, it's a little intimidating, but beautiful at the same time, because it is a creature that I may never see again.
Captain Bates says the animal was at least five metres long.
Suzy Grumbo, the young woman who captured the scene on her smartphone, also spoke about this unexpected meeting:
It's definitely an experience that makes you humble. I went from a young woman in a small city to a young woman with a great white shark.
