Aldabrachelys is a genus of giant tortoises, best known for the Aldabra giant tortoise (Aldabrachelys gigantea). These tortoises are native to the Aldabra Atoll in the Seychelles. They thrive in a range of habitats, including coastal dunes, mangrove swamps, and grasslands. Common characteristics of this genus include their large, domed shells, thick limbs, and slow-moving nature. They are herbivores, primarily feeding on grasses, leaves, and other vegetation. These tortoises are known for their longevity, with some living over 150 years. Their unique ability to survive without water for long periods is another interesting feature.
