It is possible, though perhaps unlikely, that among the remaining giant tortoises of the Galápagos Islands, there exists an old-timer that was a hatchling at the time of Charles Darwin's famous visit in 1835. Giant tortoises are the longest-lived of all vertebrates, averaging over 100 years. The oldest on record lived to be 152.
They are also the world's largest tortoises, with some specimens exceeding 5 feet (1.5 metres) in length and reaching 550 pounds (250 kilograms).
Average life span in the wild: 100 years+
Size: 4 ft (1.2 m)
Weight: 475 lbs (215 kg)
Did you know? Today the 3,000 to 5,000 tortoises that live on Volcano Alcedo on Isabela Island are the largest group of giant tortoises in the Galápagos.
