Examples
Aldabra Giant Tortoise (Aldabrachelys gigantea)
Originating from the Aldabra Atoll in the Seychelles, the Aldabra giant tortoise is the second-largest tortoise in the world. It thrives in grasslands and scrub areas, feeding on native vegetation. Conservation efforts have helped recover its population, although it remains vulnerable due to habitat loss and climate change.
Galápagos Giant Tortoise (Chelonoidis nigra)
Famous for its role in Charles Darwin's theory of evolution, the Galápagos giant tortoise is native to the Galápagos Islands. It has a distinct saddle-shaped shell that aids in reaching higher vegetation. These tortoises inhabit rocky areas and forests, feeding on grasses, leaves, and cacti. Overhunting and introduced species have severely decreased their numbers.
Vulnerability
Both the Aldabra and Galápagos giant tortoises have faced threats from human activity, including overexploitation and habitat destruction. Conservation measures, such as breeding programs and protected areas, are essential to ensure their survival and restore natural populations.
