Definition
The painted treeshrew (Tupaia picta) is a small, diurnal mammal belonging to the order Scandentia and the family Tupaiidae. It is native to the island of Borneo in Southeast Asia.
Overview
The species inhabits primary and secondary lowland tropical rainforests, typically below 1,000 m elevation, where it occupies the understory and lower canopy. It is arboreal and omnivorous, feeding on insects, other arthropods, small vertebrates, fruit, and nectar. Like other treeshrews, the painted treeshrew is active during the day and exhibits a high metabolic rate. Reproductive data are limited, but breeding is thought to occur year‑round with litters of one to three young.
The International Union for Conservation of Nature (IUCN) classifies the painted treeshrew as Least Concern, citing its relatively wide distribution across Borneo and tolerance of modest habitat disturbance. However, ongoing deforestation poses a potential future threat.
Etymology / Origin
- Genus: Tupaia derives from the Malay word “tupai,” meaning “squirrel,” reflecting the animal’s superficial resemblance to squirrels.
- Species: picta is Latin for “painted,” a reference to the animal’s distinctive, multicoloured pelage.
- Common name: “Painted treeshrew” directly translates the Latin species epithet and highlights its conspicuous coloration.
Characteristics
| Trait | Description |
|---|---|
| Size | Head‑body length 15–18 cm; tail length 13–16 cm; weight 150–200 g. |
| Pelage | Dorsal fur is dark brown to black with striking orange‑red or reddish‑brown patches on the sides and flanks; ventral surface is pale or white. The tail is banded with alternating dark and light rings. |
| Skull & dentition | Typical treeshrew dental formula: I 3/3, C 1/1, P 3/3, M 3/3 (total 40 teeth). The skull is elongated with a pronounced rostrum. |
| Sensory traits | Large, forward‑facing eyes provide acute vision; whiskers are well‑developed, aiding navigation in dense foliage. |
| Behavior | Primarily solitary but may form loose associations; uses a series of short, rapid hops for locomotion; vocalizations include high‑pitched chirps and soft clicks. |
| Reproduction | Gestation lasts approximately 45 days; juveniles are weaned after 30–35 days. Detailed breeding cycles are not fully documented. |
