Geochelone gigantea, commonly known as the Aldabra giant tortoise, inhabits the Aldabra Atoll in the Seychelles. These tortoises are known for their massive size, dome-shaped shells, and long necks, which help them reach vegetation. They are herbivorous, primarily feeding on grasses and leaves, and are known for their incredible longevity, often living over 100 years.

The Aldabra giant tortoise (Geochelone gigantea) is native to the Aldabra Atoll in the Seychelles, an island country located in the Indian Ocean. The Aldabra Atoll is part of the Outer Islands of Seychelles, which form one of the world's largest coral atolls.

The Aldabra Atoll features a tropical climate with a dry season from May to October and a wet season from November to April. The environment includes a variety of habitats such as mangrove swamps, scrubland, and coastal dunes. The area is characterized by high temperatures and humidity, with an average annual temperature of about 25-30°C (77-86°F).

Geochelone gigantea occupies diverse ecological niches on the atoll, including grasslands and scrub, where it feeds primarily on grasses, leaves, and woody plant stems. The tortoises play a crucial role in their habitat by dispersing seeds and maintaining the structure of the vegetation through their grazing habits.
