Salpingotus kozlovi

Body length 50-56mm. The tail length is about 2.5 times the body length, averaging 120mm. Ear height generally does not exceed 12mm. Weight is about 10g. From the base of the tail, sparse white long hairs are arranged regularly and extend out to both sides, and the rear end 1/4 forms a brown pencil-shaped hair bundle. The tail base 1/4 is significantly enlarged in autumn. In summer, the coat color is grey-brown, with a pure white belly. In autumn, the coat color gradually becomes lighter, until the whole body is gray-white, and the hair bundles on the tail also turn gray-brown.

In China, it is distributed in northern Xinjiang, western Inner Mongolia, Shaanxi, Gansu, and northern Ningxia. Abroad, it is distributed in Mongolia.

The three-toed cardiocraniinae belongs to the subfamily Cardiocraniinae. Although this species is widely distributed, its number is rare. There are very few specimens in the country. There is no dispute in classification, and there are 2 subspecies. There is very little information on ecology, and research is very weak.

The three-toed heart-cranial jerboa is a species endemic to the central deserts of Asia. It has a narrow distribution range and inhabits red willows with very low coverage, salt claws, flowing and semi-flowing sand dunes, and wind channels with quicksand or Gobi and sand dunes. There are many of them. The tunnel is short and straight, with a simple structure. In 1982, a cave was occasionally seen in Mingsha Mountain, Dunhuang. It was about 30-40 cm long and 3-4 cm in diameter. It began to reproduce at the end of April, and pregnant mice were found in May, with 3-4 pups per litter. Active at dusk and at night, hibernates. Feeds on plant stems, leaves and seeds. Also preys on coleoptera insects. Natural enemies are mustelids. Due to the relatively small population of each species, it is relatively difficult to capture it in the wild.
