Gary Grayson, from Salford, U.K. was on a holiday off the Isles of Scilly with a diving group when he had a truly once-in-a-lifetime encounter with a very friendly seal. The 55 year old is an experienced diver who has explored the oceans of many parts of the world and has swam with dolphins, sharks and even crocodiles. He's dived with seals in the past too, but none of those encounters could compare to this.
The seal swims right up to Gary, and doesn't seem intimidated in the least. He eventually even rolls over and receives a nice relaxing belly rub. Seals are intelligent, naturally curious animals that are known to be fairly friendly, but millions of viewers worldwide agree that this encounter was truly something special.
