Two-headed rattlesnake, named ‘Double Dave’, found in New Jersey
A rare two-headed rattlesnake – named Double Dave – has been found in a forest in the United States.
The group, which is looking after the snake, has been studying endangered and threatened reptiles and amphibians since 1977.
Bob Zappalorti, chief executive of Herpetological Associates of Burlington County, said it was the first two-headed timber rattlesnake ever found in the US state of New Jersey.
Colleagues David Schneider and Dave Burkett – hence the nickname – stumbled across the days-old rattlesnake in a known nesting area in Burlington County.
They were not expecting to find one with two heads.
“I was just blown away,” Mr Schneider told NBC News.
