'Lost' snake species rediscovered on remote Mexican island

A species of snake that had been lost for almost 80 years has been re-discovered on a remote Mexican island.

According to a study published in the PLOS ONE scientific journal, the Clarion nightsnake was found again on one of the Revillagigedo Islands, over 400 miles (650 kilometers) off Mexico's Pacific coast.

The species was first spotted by an American researcher who returned with one sample in 1936. But subsequent visits failed to find the nightsnake, and the single existing dead sample was assumed to be a labelling error. It was struck from taxonomic registries

DNA analysis taken from newly found individuals shows the long, dark spotted snake is a species most closely related to snakes from the Sonora-Sinaloa coast more than 1,000 miles (1,600 kilometers) away.
