The large treeshrew (Tupaia tana) is a treeshrew species within the Tupaiidae. It is native to Sumatra and adjacent small islands, as well as in the lowlands and hills of Borneo. Large treeshrews are the most predominantly terrestrial of all treeshrew species. They are usually on the forest floor, the primary location for their foraging, although they spend part of their time in trees. T. tana has been described as mainly terrestrial based on field observations and their morphological traits. Large treeshrews are most abundant in primary tropical rainforest, but are also found in swamp forest and secondary growth forest. T. tana has many potential predators such as the marbled cat, leopard, and clouded leopard.
Large treeshrews contribute to the maintenance of their lowland rainforest ecosystem by dispersing seeds. Tupaia tana is slightly larger than the common treeshrew (T. glis). The dorsal fur is reddish brown, shading to nearly black at the rear. There is a black stripe running from the neck half to two-thirds of the way down the back until it disappears in the darker posterior fur.

No species of the same family or order lives in Kinabatangan Wildlife Sanctuary, so these are its closest relatives here: other mammals.
With luck
About 10% of wildlife watchers report a Large Treeshrew sighting in Kinabatangan Wildlife Sanctuary on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 23rd most-seen of the 26 mammals we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
February and October
In those months about 20% of wildlife watchers report a Large Treeshrew in Kinabatangan Wildlife Sanctuary on a given day, against under 5% in April–May, July, September and November–January, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Large Treeshrew sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Large Treeshrew sightings, Kinabatangan Wildlife Sanctuary ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Sepilok (Malaysia, about 10%).
GBIF citizen-science records
It is estimated from how often the Large Treeshrew is recorded against all the mammals logged in Kinabatangan Wildlife Sanctuary (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
