‘Jonathan’ Is the Oldest Land Animal on Earth. He Could Hold the Secrets to Defying Death
Jonathan the tortoise, the world’s oldest living land animal, is still chugging along at the ripe age of roughly 194. In his fifties, Jonathan was brought to the remote island of Saint Helena, along with three other tortoises, as a gift to the British colonial governor in the 1880s.

In his fifties, Jonathan was brought to the remote island of Saint Helena, along with three other tortoises, as a gift to the British colonial governor in the 1880s. He has lived there ever since.
