World's Smallest Snake Rediscovered After 20 Years Missing

Scientists have rediscovered the Barbados threadsnake, the world's smallest-known snake, after it had not been seen for nearly two decades.

The tiny reptile, which can fit comfortably on a coin, was found under rocks in Barbados during a March 2025 survey. Its absence had led some experts to fear it had gone extinct. The rediscovery is significant for conservation efforts and highlights the challenges of tracking elusive, small species.

This find brings hope for other species thought to be lost.
