Two endangered corsac foxes have been spotted in Huihe River Nature Reserve, Hulun Buir City, north China's Inner Mongolia Autonomous Region.
With a body length at 50-60 centimeters and tail at 25-35 centimeters, the corsac fox is the smallest fox in China, living mainly in steppe, desert and semi-desert areas. In 2008, the corsac fox was listed as endangered by the International Union for Conservation of Nature.
