Have you ever imagined a snake about 4 inches (10cm)? Guess not…Apparently, such a species was found two years ago lurking under a rock on the Caribbean island of Barbados. What’s even greater than this was the fact that it was found in two “copies,” more exactly two females.

The snakes, named Leptotyphlops carlae, appear to be the smallest of the 3,100 known snake species. In fact, it is so small that it can curl up on a quarter.

They were found by Dr. Blair Hedge, a biologist from Pennsylvania State University, US. who was “thrilled” about the amazing discovery. Dr. Hedge also helped find the world’s smallest frog and lizard. Overall, he has discovered more than 65 new species of amphibians and reptiles through the Caribbean.

“It was under a rock. We got two of them. It's about as wide as a spaghetti noodle,” Hedges said.

Unfortunately, he believes the species may be on the verge of extinction living on only a few square kilometers of forest on Barbados where almost all the original forests have been cleared.

“I think it should be considered critically endangered because of its limited habitat, apparent rarity, and ongoing threats.”

Nathan Kley, a biologist at Stony Brook University in New York said it may be too soon to declare the new species the world’s smallest, as several closely related species are only fractions of an inch longer, and those are known from only a few observations or museum specimens.

"The true natural size ranges for all of these species remains extremely poorly documented," Kley said.

The new species was introduced to the scientific world in the Sunday edition of the journal “Zootaxa”
