Paul Clark discovered the 8-inch snake Monday afternoon, The (Clarksville) Leaf-Chronicle reported.
"My initial reaction was to step away," he said. "I just thought it was weird."
Carver summoned a friend, Dale Grandstaff, to examine the snake. Grandstaff, a Tennessee Wildlife Resources officer, decided to donate the snake to his alma mater.
Grandstaff said the snake was only a few days old and destined for a short life if it remained on its own. Two-headed snakes are rare and typically do not survive long because the heads are unable to coordinate on feeding and moving around.
"With millions of snakes and all the eggs that are laid, there are several babies a year probably born like this," he said. "But for them to make it in the wild, it's basically impossible."
The snake has a better chance at the university in Cookeville, Grandstaff said.
