Ssssssssnake -- Rare two-headed rattlesnake found in New Jersey

Two scientists in Burlington County found a rare two-headed rattlesnake in the Pine Barrens.
The snake, named Double Dave, has two heads that are fully formed -- four eyes, two tongues, but just one body.
The scientists are taking over his care.
According to scientists, most double-headed snakes have a hard time surviving in the wild.
