A marsupial mammal of the Boulamysidae family. It resembles rodents such as dormice, especially the European dormouse, in both appearance and habits. It has a round body and short limbs. Unlike the dormouse, its tail is exposed except for the base, and can be wrapped around something. In autumn, it accumulates fat in its body for hibernation, and becomes significantly enlarged; at the same time, fat is also accumulated in its tail, which becomes noticeably thicker. It has large ears and eyes. Its body color is yellowish brown, with black around the eyes. Its well-developed brood pouch has four nipples. It is 8.5-10 cm long, 9-11 cm long, and weighs 15-25 g.
