Tortoises are the longest-living land animals in the world, although the longest-living species of tortoise is a matter of debate. Galápagos tortoises are noted to live over 150 years, but an Aldabra giant tortoise named Adwaita may have lived an estimated 255 years. In general, most tortoise species can live 80–150 years.
Captive Galapagos tortoises can live up to 177 years. [4] For example, a captive individual, Harriet, lived for at least 175 years. Spanish explorers, who discovered the islands in the 16th century, named them after the Spanish galápago, meaning "tortoise". [5] Galápagos tortoises are native to seven of the Galápagos Islands.
These tortoises may attain a length of 25 to 36 cm (10 to 14 in), [12] with males being slightly larger than females. A male tortoise has a longer gular horn than a female, his plastron (lower shell) is concave compared to a female tortoise. Males have larger tails than females do.

If they survive these threats, the longevity of Hermann's tortoises is around 30 years. [13] One rare record of longevity is 31.7 years. [15] Compared to other tortoises (e.g. Testudo graeca), [15] the longevity might be underestimated and many sources are reporting they might live 90 years [16] or more.
