Although the tortoise looks small now, it should grow much, much bigger. In fact, the species are the third largest in the world, after Darwin's friends, the Galapagos Tortoise, and the Aldabra Giant Turtle.
The African spurred tortoise, which in Latin is Geochelone sulcata (geo - earth; chelone - tortoise; and sulcus - furrow (in reference to the distinctive scales)), is the biggest mainland tortoise in the world.
Usually they inhabit the southern edge of the Sahara desert, in northern Africa and adults are usually 18 inches (45 cm) in shell length, and weigh 70 to 100 pounds.
Specimens with 24 to 36 inch long (60-90 cm) shells weighing 150 pounds (70 kg) are not unknown and they grow from hatchling size (2-3 inches) very quickly, reaching 6-10 inches (15-25 cm) within the first few years of their lives.
The lifespan of an African Spurred Tortoise is about 30-50 years, though can live much longer - the oldest in captivity is 54 years, located in the Giza Zoological Gardens, Egypt, 1986.
