World's Smallest Snake Rediscovered After 20 Years Missing

The Barbados threadsnake, the world's smallest-known snake species, has been rediscovered in Barbados after nearly two decades without a confirmed sighting.

Scientists feared the tiny reptile, which can fit on a coin, had gone extinct until a recent survey in March 2025 uncovered its presence under rocks. The rediscovery required overturning hundreds of rocks in the Scotland District of St. Andrew, Barbados. This finding brings hope for the conservation of elusive and endangered species.

The event highlights the importance of persistent fieldwork and habitat preservation.
