Burmese pythons, an invasive species first identified in Everglades National Park more than 20 years ago, are distributed across more than a thousand square miles in southern Florida but have been found across the state and are slithering north. They may even reach Georgia.

They’re among the largest snakes in the world, with adult animals averaging between 10 and 16 feet long, according to the University of Florida.

Because pythons are invasive and a threat to native wildlife, Florida Fish and Wildlife works with partners and the public to hunt and kill the snakes, including the annual Florida Python Challenge.
