The northern treeshrew (Tupaia belangeri) is a treeshrew species native to Southeast Asia.[1]

In 1841, the German zoologist

Tupaia tana to assign a specific rank.[2][3]

Characteristics

Adults weigh 0.2 kg (0.44 lb). The maximum longevity of the northern treeshrew is 11 years.[citation needed]

Besides humans, the northern treeshrew is the only mammal known to willingly consume spicy food.[5]

In medical research

The northern treeshrew has attained growing interest for use as a medical model. In 2002, an article was published describing that its primary

hepatocytes could be used as a model for studying the Hepatitis C virus, which is a major cause of chronic hepatitis worldwide.[8]
It was also used in studies on the development of photo reception,[9] investigation of retinal cones,[10] and refractive state and ocular component dimensions of the eye.[11] Many studies have been conducted regarding eye structure, development, and vision using the northern treeshrew model because of the similarity to human eye structure and sight that is uncharacteristic of conventional small lab animals, such as rodents.[12]
