The Aldabra Tortoise (Aldabrachelys gigantea), native to the Aldabra Atoll in the Seychelles, is one of the largest tortoise species in the world. Adult males can weigh up to 550 pounds (250 kg) and reach lengths of 4 feet (1.2 meters), making them true giants of the tortoise world. These tortoises are known for their long lifespan, often living over 100 years, with some individuals possibly exceeding 150 years. Their slow metabolism and hardy nature contribute to this remarkable longevity. In their natural habitat, Aldabra Tortoises play an essential ecological role by grazing on grasses and small shrubs, helping to shape the island's vegetation.

Aldabra Tortoises are also famous for their adaptability to extreme environmental conditions. During periods of drought, they are capable of surviving with very little water, extracting moisture from the vegetation they consume. Additionally, they have an interesting behavior of "rearing up" on their hind legs to reach vegetation that is normally out of their reach, allowing them to graze on low-hanging branches. Socially, they are often seen in groups, particularly around water sources or areas with abundant food. Their gentle nature and slow, deliberate movements make them fascinating creatures to observe, and they are often highlighted as symbols of conservation efforts to protect endangered species.
