The Aldabra Giant Tortoise (Geochelone gigantea), from the islands of the Aldabra Atoll in the Seychelles, is one of the largest tortoises in the world. This species is widely referred to as Geochelone gigantea but is now placed in the genus Dipsochelys (or sometimes in the invalid genus Aldabrachelys) as Dipsochelys dussumieri.
