African spurred tortoise
Centrochelys sulcata

— Where the name comes from
Centrochelys is “spurred turtle”, from the Greek kéntron, the goad: on its thighs it carries two or three conical tubercles. Sulcata means “furrowed”, for the deep growth rings that score each scute like the rings of a trunk. It is the largest mainland tortoise in the world, after the two island giants of the Galápagos and Aldabra.

— What sets it apart
Its tunnels are the Sahel’s block of flats: jackals, snakes, rodents, spiders and lizards live in them and would not survive the summer without that shade. The same animal is also the most embarrassing case in the exotic pet trade — it is sold as a little house tortoise and within a decade becomes an eighty-kilo block digging under the foundations. In the United States there are shelters that take in nothing but abandoned animals of this species.
