Lost Species of Snake Is Rediscovered

After a researcher could find only a single specimen of the Clarión nightsnake in 1936, scientists discredited its discovery. Now, researchers from the Smithsonian Institution’s National Museum of Natural History have proved that Hypsiglena unaocualrus does exist by finding 11 more of its kind on Mexico's Clarión Island. The species, described this month in PLOS ONE, is nocturnal and is located on a secluded island that's 700 kilometers away from Mexico's mainland.
