The corsac fox is a medium-sized fox found in steppes, semi-deserts and deserts in Central Asia, ranging into Mongolia and northeastern China. It is also known as the steppe fox.

As an adaption to the arid climate in which they live, corsac foxes can forego food and water for extended periods of time. The corsac fox is an opportunistic forager and hunter. Its diet varies throughout its range, but consists foremost of small and medium-sized vertebrates, insects and small rodents.

During the winter, their coat becomes much thicker and silkier in texture, and is straw-grey in color, with a darker line running down the back. Corsac foxes have keen eyesight and hearing and an acute sense of smell. They have a number of scent glands, some of which produce pungent odors. The glands are found in the anal region, above the base of the tail, and on the paws and cheeks.

The major threat posed to the corsac fox is poaching, as it is a valuable fur-bearing species and has been harvested by humans since the Bronze Age for subsistence and commercial purposes. It is a slow runner and therefore easily caught by hunters.

Other threats include overgrazing by livestock and landscape development; the decline of marmots may also impact the species in some areas, as it often uses marmot burrows as daytime resting locations.
