19 year old Chris Kreis was fishing with his family off the coast of Captiva, Fla., when they saw a 30-foot, 50,000-pound whale shark swim past the boat. Since whale sharks are gentle creatures, Kreis decided to go for a swim.  He said quote “I decided, you know what, maybe I should go try and swim with him. I might not be able to do it ever again.”  About the ride he said "When I started holding on I felt the whale shark it started moving itself, it felt the drag and it didn't really want me on there so I let go and that's it." I know whale sharks are gentle and all...but as a parent...would you really let your kid do this? And then film the whole thing? It might have some not so gentle friends with it in the water. Just sayin'.
