The African Spur Thigh Tortoise, or the Sulcata tortoise as it's also known, is one of the largest tortoise species on the planet. These are long-lived creatures. Tortoises, of course, are different from turtles. Tortoises you'll find on land. Look at those big diggers he's got in the front there. He digs tremendously large holes in his native Saharan habitat. He comes from the southern rim of the Saharan desert in Africa. And he is the third largest tortoise species on the planet. Very, very important creature in the environment that he lives.
