The desert tortoise is a common species found in the Great Basin's desert ecosystems.

The Great Basin is home to several species adapted to its dry, desert-like conditions. The desert tortoise (Gopherus agassizii) is one of the most notable animals found in this region. It is well adapted to survive in the arid climate, with a diet mainly consisting of grasses, herbs, and cacti. While polar bears, grizzly bears, and elephants are not native to the Great Basin, the desert tortoise thrives in the region's hot, dry environment.
