I met Shealy and Scholle while I was on an expedition in February to hunt invasive Burmese pythons in the Everglades. It definitely does not belong in the Florida Everglades. A nonvenomous constrictor native to South America, the green anaconda is the biggest, heaviest species of snake in the world. Rick Scholle, who runs the campground’s roadside zoo, examined the snake and realized that he was looking at a juvenile green anaconda. Trail Lakes Campground just happened to have a herpetologist on staff.
