The greater Bermuda snail has recovered after a decade of conservation work.
Scientists once believed the species extinct in Bermuda.
In 2014, researchers found a small surviving population in Hamilton.
Conservationists launched an international rescue effort soon after.
Chester Zoo bred thousands of snails in special pods.
Since 2019, teams have released more than 100,000 snails into protected habitats.
The species suffered from habitat loss, climate change, and invasive predators.
Biosecurity measures now protect the snails from wolf snails and flatworms.
Surveys show stable populations in six locations.
Researchers will publish the findings in Oryx.
Scientists say the snail’s return supports wider ecosystem recovery.
