For nearly two decades, no one had spotted the world’s smallest-known snake.

Some scientists worried that maybe the Barbados threadsnake had become extinct, but one sunny morning, Connor Blades lifted a rock in a tiny forest in the eastern Caribbean island and held his breath.

“After a year of searching, you begin to get a little pessimistic,” said Blades, project officer with the Ministry of Environment in Barbados.

The snake can fit comfortably on a coin, so it was able to elude scientists for almost 20 years. Too tiny to identify with the naked eye, Blades placed it in a small glass jar and added soil, substrate and leaf litter.
