A button-sized snail once feared extinct in its Bermudian home is thriving again after conservationists bred and released more than 100,000 of the molluscs.
The greater Bermuda snail (Poecilozonites bermudensis) was found in the fossil record but believed to have vanished from the North Atlantic archipelago, until a remnant population was discovered in a damp and overgrown alleyway in Hamilton, the island capital, in 2014.
