The Barbados threadsnake (Leptotyphlops carlae) is a species of blind threadsnake. It is the smallest known snake species. This member of the Leptotyphlopidae family is found only on the Caribbean island of Barbados. At the time of publication, August 2008, L. carlae was described as the snake species with the smallest adults in the world. The first scientific specimens taken by the research team were found under rocks in a forest. The snake is thought to be near the lower size limit for snakes, as young snakes need to attain a certain minimum size to find suitable food.
