A species of tiny snail has been introduced again from the brink of extinction.
The Desertas Island land snails have been believed to have disappeared altogether for 100 years, however consultants have managed to breed them in captivity after discovering tiny populations on an remoted island known as Desertas Grande within the Madeira Archipelago, Portugal.
Now greater than 1,300 of the critically endangered snails are being launched into the wild on the close by island of Bugio.
The rescue effort started when a staff of conservationists found two species of the snail surviving on the rocky cliffs of Desertas Grande.
Fewer than 200 particular person snails have been present in every inhabitants.
They have been believed to be the final of their sort so the conservationists introduced them to zoos within the UK and France as a part of efforts to avoid wasting the species.
Sixty of the pea-sized snails have been flown to Chester Zoo, the place consultants started a singular breeding programme to spice up their numbers.
Each of the species have been efficiently bred in captivity for the primary time ever.

Dr Gerardo Garcia, Chester Zoo’s head of ectotherms, mentioned: “When the snails first arrived in Chester the very way forward for the species was in our palms.
“As a zoo conservation neighborhood, we knew nothing about them. They’d by no means been in human care earlier than and we needed to begin from a clean piece of paper and check out to determine what makes them tick – easy methods to look after them, easy methods to create an surroundings by which they might flourish, and easy methods to encourage them to breed.”
He mentioned the snails had been “on the sting of extinction” however now they’ve a “likelihood of creating a comeback”.
The snails had initially been all however worn out because of invasive goats, rats and mice.
Specialists selected to relocate them to Bugio island as they might be much less in danger from these threats.
Every of the snails has been individually marked with a tiny quantity of infra-red paint to allow them to be rigorously monitored.
