Giant Tortoise

Chelonoidis nigra

Vulnerable

Giant tortoises are among the most iconic reptiles, known for their impressive size and long lifespan. These tortoises are characterized by their large, dome-shaped shells, which can measure over 1.5 meters in length. Their sturdy, elephantine legs support their massive bodies, which can weigh up to 417 kilograms. Giant tortoises are primarily found in the Galápagos Islands, where they have evolved into several subspecies, each adapted to the specific conditions of their island habitat. These tortoises are herbivores, feeding on a diet of grasses, leaves, and fruits. They are known for their slow, deliberate movements and can live for over 100 years, with some individuals reaching ages of 150 years or more. An interesting fact about giant tortoises is their ability to survive for long periods without food or water, a trait that helped them endure long sea voyages when they were unfortunately exploited by sailors in the past. Conservation efforts are crucial for these tortoises, as they are classified as Vulnerable due to habitat destruction and introduced species.
