In 1919 the British governor of Seychelles sent a gift of four Aldabra Giant Tortoises to Changuu from the island of Aldabra.[1] These tortoises bred quickly and by 1955 they numbered around 200 animals. However people began to steal the tortoises for sale abroad as pets or for food and their numbers dropped rapidly. By 1988 there were around 100 tortoises, 50 in 1990 and just seven by 1996.[2] A further 80 hatchlings were taken to the island in 1996 to increase the numbers but 40 of them vanished. The Zanzibar government, with assistance from the World Society for the Protection of Animals built a large compound for the protection of the animals and by 2000 numbers had recovered to 17 adults, 50 juveniles and 90 hatchlings. The species is now considered vulnerable and has been placed on the IUCN Red List by the International Union for Conservation of Nature. More tortoises, mainly juveniles, continue to be brought to the island from other locations for conservation.[2] There is a dedicated foundation on the island which looks after the tortoises' welfare.[1] Visitors are able to observe and feed the tortoises.[2]

The Aldabra giant tortoise (Aldabrachelys 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 Aldabrachelys gigantea but has also been placed in the genus Dipsochelys as Dipsochelys dussumieri.[1]

The carapace is a brown or tan color with a high domed shape. It has stocky, heavily scaled legs to support its heavy body. The neck of the Aldabra Giant Tortoise is very long, even for its great size, which helps the animal to exploit tree branches up to a meter from the ground as a food source.

Similar in size to the famous galapagos giant tortoise, its carapace averages 120 centimetres (47 in) in length. The average weight of a male is around 250 kilograms (550 lb), but one male at the Fort Worth Zoological Park weighs over 360.25 kilograms (794.2 lb). Females are generally smaller than males, with average specimens measuring 90 centimetres (35 in) in length and weighing 150 kilograms (330 lb).
