Such an event took place at Galapagos Islands where conservationists recently found a giant tortoise from a species they thought had gone extinct a century ago.
It was then taken to the main Galapagos conservation centre on Santa Cruz island.
Speaking to reporters on the amazing discovery, Washington Tapia of the Galapagos Conservancy said:
The animal exceeds 100 years in age and is a very old tortoise.
They have no natural predators but their numbers were decimated in the 18th and 19th century as sailors stored them as fresh meat on Pacific voyages, owing to their ability to endure long periods without food and water.
Hopefully, this is the first of many such discoveries so that we could see these magnificent creatures repopulate the islands.
