Burmese pythons, the large constrictor snakes eating their way across the Florida Everglades and destroying native wildlife, have a low detectability rate, meaning they're very difficult to find.
Sometimes hunters must brave difficult terrain and conditions to find them.
Jason Leon is one of the youngest permitted python hunters in Florida and he holds the record for the largest python ever caught in North America. To look for pythons, he often goes snorkeling in alligator-infested ponds and canals, peeking into nook and under sunken branches.
Never miss a local story.
Pythons are strong swimmers, and scientists believe many of them hide under water. Leon gently pushes aside giant gators as he searches the murky ponds of the Glades.
In this week’s video snippet -- outtakes of The Python Invasion documentary that will broadcast on WPBT2 later in the year -- Leon explains what motivates him to brave what most would consider terrifying in search of the elusive snake.
