Hogzilla is the name given by Dr. Eliahu Katz to a supposed male hybrid of wild hog and domestic pig that was shot and killed by Chris Griffin in Alapaha, Georgia, United States, on June 17, 2004 on Ken Holyoak's fish farm and hunting reserve.
It was alleged to be 12 feet (3.7 m) long and weighed over 1,000 pounds (450 kg). It was originally considered a hoax.
The animal's remains were exhumed in early 2005 and studied by Dr. Oz Katz and his father, Dr. Eliahu Katz, for a documentary and a book they wrote together. In March 2005, these scientists determined that Hogzilla actually weighed 800 pounds (360 kg) and was between 6.9 feet (2.1 m) and 8.6 feet (2.6 m) long, diminishing the previous claim.
DNA testing was performed, revealing that Hogzilla was a hybrid of wild boar and domestic pig (Hampshire breed). However, compared to most wild boars and domestics, Hogzilla is still quite a large and extraordinary specimen.
Many other 'giant wild pigs' have been observed in the wild.
