A cool video has emerged of a whale shark swimming really close to a boat off the coast of Florida.

The footage, filmed in June, shows the huge whale shark approaching the fishing boat.

The filmer wrote online: "My family and I were fishing about 14 miles off the coast of St George Island, Florida, when a giant Whale Shark approached the boat."

"The shark was about 16 feet long. I was able to reach out and touch its head when it came close."
