Which land animal lives the longest?

Giant tortoises, such as those of the Galápagos and Aldabra, are the longest-lived land animals, routinely surviving beyond a century and sometimes past 150 years. A famous tortoise named Jonathan, living on the island of Saint Helena, is estimated to be over 190 years old, making him the oldest known living land animal. Their slow metabolism and unhurried lifestyle are thought to contribute to their remarkable longevity. In the ocean, some species live even longer.
