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.
Black rats had been eating both tortoise eggs and hatchlings, effectively destroying the future of the tortoise population. Only the longevity of giant tortoises allowed them to survive until the Galápagos National Park, Island Conservation , Charles Darwin Foundation, the Raptor Center, and Bell Laboratories removed invasive rats in 2012.
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.

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 Giant tortoises originally made their way to islands from the mainland via oceanic dispersal.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]
Gopher tortoises, like other tortoises of the genus Gopherus, are known for their digging ability. Gopher tortoises spend most of their time in long burrows (up to 80% of their time). [19] On average, these burrows are 15 feet (4.6 m) long and 6.5 feet (2.0 m) [13] deep, but can extend up to 48 feet (15 m) in length and 9.8 feet (3.0 m) deep. [14]
The African spurred tortoise (Centrochelys sulcata), also called the sulcata tortoise, is an endangered species of tortoise inhabiting the southern edge of the Sahara Desert, the Sahel, in Africa. It is the largest mainland species of tortoise in Africa, and the third-largest in the world, after the Galapagos tortoise and Aldabra giant tortoise.
