The world’s largest species of tortoise is the Galápagos giant tortoise, native to the Galápagos Islands in Ecuador. These tortoises can weigh over 400 kilograms (880 pounds) and can live for more than 100 years, making them some of the longest-lived animals on the planet. They exhibit remarkable size variations based on their specific island habitats, with some individuals reaching lengths of up to 1.5 meters (5 feet). Conservation efforts have been implemented to protect their populations, which have been threatened by habitat loss and introduced species. They remain an integral part of their unique ecosystem.
