The Bermuda land snail has returned from extinction.
The animal was thought to have disappeared many years ago until an empty shell was brought into the office of Mark Outerbridge, a wildlife ecologist for the Bermuda government, in 2014.
Live snails were then found in a nearby alleyway in country's capital city Hamilton and were transported to Chester Zoo where they underwent a breeding program and over 4,000 snails were raised.
The snails - which are also known as the ''Lazarus species'' - were returned to their native territory and more will soon be brought back to their homeland.
Outerbridge said: ''It turned out that, yes, this was in fact the greater Bermuda land snail, a species that we thought had gone extinct 40 years earlier.
''He came back the next day with a fresh one, a live one in his hand, and that's how I was thrust into this conservation project.''
