Worm-Like Snake

Not only is Leptotyphlops carlae the smallest snake, it might possibly be the smallest possible snake, said biologist Blair Hedges. Any smaller, its offspring might not be able to find food and consume insects on its own. At about 10cm, it looks like an earthworm. The snake, found in Barbados, is on the verge of extinction due to deforestation and the fact that the species only live in the remaining few square kilometers of forest.
