From Wikipedia
A feral pig is a domestic pig which has gone feral, meaning it lives in the wild. The term feral pig has also been applied to wild boars, which can interbreed with domestic pigs. They are found mostly in the Americas and Australia. Razorback and wild hog are sometimes used in the United States in reference to feral pigs or boar–pig hybrids.
