The two species of gigantic tortoise, both living in the Galápagos Islands (famously studied by Charles Darwin), have different shaped shells. The shells of C. elephantopus on Floreana Island were saddle-shaped while tortoises on other islands, including C. becki, had domed-shaped shells. These giant tortoises can weigh nearly 900 pounds (408 kilograms) and reach almost 6 feet(1.8 meters) in length.
