Burmese Pythons Invade Florida

Snake Hunter
Dave Leivman shows off a 9-foot python he recently captured in Everglades, Florida on Jan. 17, 2012. The state licenses hunters to help eradicate the invasive species. Wildlife officials say that tens of thousands of pythons—at minimum -- inhabit South Florida. Exotic pet owners release many snakes when they grow to large to be kept.
