In 2008 L.A. Innes of Jamestown, Saint Helena, auctioned a collection of images taken during the Boer War. This one shows a prisoner standing next to a tortoise on the island. The tortoise was mature at the time of the photograph, which was taken in 1900, and investigators were surprised to find that he’s still alive — “Jonathan” lives on the grounds of the governor’s residence, blind in one eye but still active and mating with other tortoises.

If he was 70 at the time Innes’ photograph was taken, then he’s 184 today — the oldest living reptile on earth.
