World's smallest snake?



Evolutionary biologist Blair Hedges has great luck with tiny herps. In 2001, he co-discovered the world's smallest lizard (above left) on an island off the coast of the Dominican Republic. Now, the Penn State evolutionary biologist has described what seems to be the world's tiniest species of snake (above right). Found in Barbados, the threadsnake averages just 100 millimeters long. From Science News:

Islands are often homes for very large or very small species. Some lineages on continents never make it out to islands, so island dwellers have opportunities to fill niches they wouldn't on the mainland. Hence, when searching for an unusual form of an animal, such as minis or giants, islands make good places to start looking.
