According to Harry Snelson of the American Association of Swine Veterinarians, pigs can swim. He is quoted as saying, "pigs are actually pretty good swimmers over short distances."
All pig species Dr. Snelson is aware of can swim. The pigs use the doggie paddle style of swim.
On an uninhabited island in the Bahamas called Big Major Cay, there lives about 20 swimming pigs. Locals call the island Pig Beach. These pigs know that when a person visits or boat passes by, a meal will present itself. The pigs dip into the water and will eagerly swim up to a boat for a free snack.
