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 can weigh as much as 417 kg (919 lb) and can grow to be 1.3 m (4 ft 3 in) long. Giant tortoises originally made their way to islands from the mainland via oceanic dispersal. Tortoises are aided in such dispersal by their ability to float with their heads up and to survive for up to six months without food or fresh water. [3]

Tu'i Malila, a radiated tortoise, died at the age of 188 in May 1966, at the time the oldest verified vertebrate. [109] This tortoise was hatched in 1777. Harriet, a Galápagos tortoise, died at the age of 175 in June 2006. [110] Timothy, a Greek tortoise, born in Turkey died at the age of 165 on 3 April 2004 in the UK. [111]
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.
The Nature Protection Trust of Seychelles takes consolation from producing a new generation of many young tortoises which will live for at least 100 years. In that time there may be an opportunity to establish pure populations of these tortoises. These animals live longer than short-term management and development perspectives. [10]
