Sean Manning swims with a nine foot long American Alligator at Jungle Island animal theme park in Florida. Carrying no protection and breathing through a snorkel, Sean has to rely on the mood and attitude of the alligator before he attempts to get close. Eventually swimming head to head with the well-known 'killing machine'. With 80 razor sharp teeth and jaws that crush at 3000 pounds per-square-inch, Sean had better not get complacent. [CFP]
