It's a whale of a tale!
A charter captain on a fishing trip got a ride on a whale shark, the largest fish in the world, off the coast of Florida.
Jamie Bostwick says it's always been on his bucket list, so he jumped in, grabbed the shark's fin and hung on.
"The whale shark basically came right to us," he said. "It was as curious about us as we were about it."
This is not illegal, by the way, but experts say humans can hurt these types of sharks with too much contact.
The whale shark swam with three other people and stuck around for about 20 minutes.
