African Spur Thigh tortoise is native to South Sahara deserts, covering Senegal, Mauritania, Mali, Chad, Sudan and Ethiopia. This animal 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 consists of several scutes, each featuring growth rings. Thick skin keeps moisture inside the body and thus prevents dehydration.
