African spurred tortoise
At the Detroit Zoo
In 2005, a Detroit Zoo keeper discovered a tortoise walking down the 10 Mile Road service drive outside of the Zoo. The tortoise was taken in and named Tubby. He was estimated to be 3 to 5 years old at the time, and was about the size of a dinner plate; now he is nearly 2 and a half feet long! Tubby shares a habitat with a guanaco in the warm-weather months.
African spurred tortoises are well camouflaged by their overall sandy coloration. They have thick golden to yellow-brown skin and brownish carapaces. The broad, oval carapaces display prominent serrations at the front and back margins and noticeable growth rings on each scute, which become marked with age. Large overlapping scales cover the front surface of the forelimbs, while the hind surface of the thigh bears two or three large conical spurs, from which they earn their name.
African spurred tortoises are the largest tortoise of the African mainland.
