The three-toed cardiodial jerboa is the smallest jerboa in the world, living in the extremely poor Gobi desert and desert environment, and likes to burrow in small sand dunes at the base of shrubs such as strange willows. Interestingly, they hibernate by relying on fat stored in their tails to survive the winter.
Animal classification: Chordate Phylum Mammalian rodents Jeringa family Three-toed cardiocranial jerboa genus
English name: Koslov's Pygmy Jerboa
Distribution area: China is found in Xinjiang (northeast and south of the Tianshan Mountains), Mongolia, Ningxia and Gansu, and abroad in southern Mongolia.
Species Small Science Popularization:
The three-toed cardial jerbok has a more heterogeneous diet, feeding on young leaf seeds and small insects of plants. Because of their small size, their subcutaneous fat layer is not developed, in order to cope with the cold of winter and food shortages, three-toed cardiovascular chilios will eat a lot when food is plentiful, and store fat in the tail. In the winter, they will go into hibernation, the body's metabolism remains at a very low level, relying on the fat stored in the tail to survive the winter. Because the three-toed cardiocranial jerboa is very rare, people know about it relatively limited. The three-toed cardiocranial jerboa is about 5 cm long, has a tail of about 12 cm, and weighs about 10 g. Compared to other jerboas, its hind paws are only three toes, its ears are small, its white whiskers are long, and it has a short white hair around its mouth, which is close to the pig's nose and is very recognizable. The dorsal body hair of the three-toed cardiomyobo is grayish brown, which turns grayish white in autumn and pure white on the abdomen. Its tail hairs are sparse, with brush-like hair bundles at the ends that do not form a tail spike.
Population status:
The population is unknown, the distribution range is relatively wide, but the number is sparse, there is no protection level, and the Red List of Vertebrates of China assesses it as non-hazardous (LC).
