The African Spur Tortoise has distinctive spurs on the rear legs, which give it its name. The tortoise shell can reach 36 inches in length, and weight exceeds 220 lbs. The carapace of the African Spur Tortoise consists of several scutes, each featuring growth rings. Thick skin keeps moisture inside the body and thus prevents dehydration of the African Spur Tortoise.
