8. Aldabra Giant Tortoise
The Aldabra giant tortoise is a living testament to slow and steady longevity. Many of these tortoises live over 150 years, with some rare individuals surpassing the 200-year mark.
Their exceptionally slow metabolism is believed to play a key role in this remarkable lifespan, helping to reduce cellular wear and prolong life. As Encyclopedia Britannica explains, these gentle giants are among the world’s longest-lived land animals, quietly outlasting generations of other species.
