Small pencil-tailed tree mouse

The small pencil-tailed tree mouse, also called the lesser pencil-tailed tree mouse (Chiropodomys pusillus), is a species of arboreal rodent in the family Muridae. The Wikipedia article that serves as this entry's source says it is endemic to Borneo, where it is known only from Sabah and Sarawak in Malaysia and from southern Kalimantan in Indonesia, although it likely occurs more widely. Arboreal means that it lives in trees. The article gives no body measurements, diet, lifespan, population figure or conservation category, so those details are left blank here rather than guessed, and the description is limited to what that single short article states.
