For the first time in more than a century, researchers have discovered a new boa species in the Dominican Republic. The Hispaniolan vineboa (Chilabothrus ampelophis) was discovered in a mountainous region near the border of Haiti. The species may be the smallest boa in the world—the longest one researchers discovered was less than 1 meter in length. The newly described snakes have large, protruding eyes, a zigzag pattern and a square snout. Researchers didn’t find many of them in their surveys and are concerned the snakes may be in trouble.
