Florida's Everglades is known for its alligators, and in recent years, pythons. Burmese pythons aren't native to the Everglades. But over the last two decades, the snakes, which can grow up to 20 feet, have become established there and taken a big toll on native wildlife.
With the pythons, there's another new Florida species — the python hunter. They've been featured on National Geographic and the Discovery Channel. And hunters are descending on the Everglades this month for a competition — the Python Challenge.
