Description
Description

Treeshrews, belonging to the order Scandentia, are small, squirrel-like mammals found primarily in the tropical forests of Southeast Asia. Despite their name and appearance, they are not true shrews and have a closer evolutionary relationship with primates. These agile creatures inhabit dense forests, where they scurry through the undergrowth and trees in search of insects, fruits, and seeds. Treeshrews play a pivotal role in their ecosystems, both as seed dispersers and as prey for larger animals. Their evolutionary history is intriguing, as they provide insights into early primate characteristics, bridging a gap in our understanding of mammalian evolution.

Anatomy
Anatomy

Treeshrews are small, nimble mammals resembling squirrels with slender bodies, long tails, and pointed snouts. Their sharp claws and flexible limbs aid in their expert tree-climbing, allowing them to deftly navigate forest canopies. Primarily diurnal, treeshrews have keen eyesight and a well-developed sense of smell to hunt insects and forage for fruits. Their large, rounded ears are sensitive to sound, helping them communicate through a range of vocalizations and detect predators. Though they're not prolific communicators, their sounds play a crucial role in social interactions and territorial defense. Overall, their anatomy is a blend of agility and sensory acumen, perfectly adapted to a life amidst the trees.

Human Interaction
Human Interaction

Treeshrews, often overshadowed by their primate cousins, have maintained a relatively obscure relationship with humans. These small mammals, dwelling primarily in the treetops of Southeast Asia, have seldom featured in popular culture or folklore. Scientifically, they've sparked interest due to their unique evolutionary position, offering insights into mammalian ancestry.

Unfortunately, like many forest inhabitants, treeshrews face threats from habitat destruction and deforestation. Conservation efforts are gradually recognizing the need to protect these creatures, not only for their ecological role but also for their potential scientific value in understanding the complex tapestry of mammalian evolution. As awareness grows, so does the hope for their future.

Common Questions
Common Questions
What is the difference between a treeshrew and a squirrel?

First, you need to know that the treeshrew is not as arboreal as the squirrel. It has a long and pointed snout while the squirrel has a more rounded face and a bushier tail. Another feature that separates them is that the squirrel has two cream and black stripes on its sides.

What are treeshrews related to?

The closest living relatives of the treeshrew are primates. Although other studies show that they also have some relation to bats and even colugos. Despite being an insectivore and resembling squirrels, treeshrews are not real shrews. These primitive primates can be nocturnal and arboreal and prefer a solitary life.

Are treeshrews smart?

Treeshrew may be related to humans but are not as smart as humans, maybe a mouse. What they beat humans on is their ability to seek hot pepper and drink the nectar of the Bertram plant, which has a high concentration of alcohol. Hence, they have a tremendous tolerance for pungency.

Pen-Tailed Treeshrew (Ptilocercus lowii)
Scale illustration of an average Pen-Tailed Treeshrew compared to other treeshrew species

A major discovery scientists have found about the Pen-tailed Treeshrew (Ptilocercus lowii) is that it can consume a lot of alcohol without getting drunk. This alcohol is found in the nectar of the bertam palm. You will mostly find this treeshrew in rubber farms, forest edges, and primary and secondary forests in Thailand, Malaysia, and nearby small islands. The belly is whitish or yellow, while the back is gray or light brown. But it is the “pen tail” plume-like hair on the end of the tail that makes it easily identifiable. This hair is black, fading to white. Alternatively, you can also identify it with the black eye mask. The pen-tailed treeshrew is nocturnal, social, and omnivorous.

The Pen-Tailed Treeshrew has a body length in the range of 5.1”-5.5” (13-14 cm) and total weight of 1.8-2.1 oz (50-60 g). The Pen-Tailed Treeshrew has a standing height of roughly 2.4”-2.75” (6-7 cm), body width of 1.6”-2” (4-5 cm), and tail length of 6.3”-7.5” (16-19 cm). The typical lifespan of the Pen-Tailed Treeshrew is between 2-12.5 years.

Ruddy Treeshrew (Tupaia splendidula)
Comparison illustration of the size of a Ruddy Treeshrew to other species of treeshrews

The Ruddy Treeshrew (Tupaia splendidula) is endemic to Indonesia and is omnivorous. It prefers lower elevations but on trees with foliage. The most recognizable feature is the reddish-brown bushy tail, slender profile, and high alertness. This is because of their good sense of smell, vision, and hearing. The ruddy treeshrew is arboreal, diurnal, viviparous, and solitary. The face is pointed and the hind legs are longer than the forelimbs, enabling it to easily jump and climb trees. The upper part is dark brown or reddish-brown and the belly is white.

The Ruddy Treeshrew has a body length in the range of 5.9”-7.3” (15-18.5 cm) and total weight of 3.9-5.3 oz (110-150 g). The Ruddy Treeshrew has a standing height of roughly 2.75”-3.5” (7-9 cm), body width of 2”-2.6” (5-6.5 cm), and tail length of 4.7”-5.9” (12-15 cm). The typical lifespan of the Ruddy Treeshrew is between 2-12.5 years.

Northern Smooth-Tailed Treeshrew (Dendrogale murina)
Comparison illustration of the size of a Northern Smooth-Tailed Treeshrew to other species of treeshrews

The Northern Smooth-tailed Treeshrew (Dendrogale murina) is an omnivore feeding mostly on fruits and also invertebrates. It is endemic to the tropical rainforests of Cambodia, Vietnam, and Thailand. As a smooth-tailed shrew, it is separated from similar shrews by its facial markings, which are light-colored, especially on the underside, while the dorsal surface is brown/black. The hair is short, the tail dark, and the shoulders lack strips. Besides, the claws are small. It is mostly arboreal and is active during the day. The body is slender, and the muzzle is pointed. Infants depend on the mother, as they are born blind and hairless.

The Northern Smooth-Tailed Treeshrew has a body length in the range of 4.5”-5.3” (11.5-13.5 cm) and total weight of 1.2-1.9 oz (35-55 g). The Northern Smooth-Tailed Treeshrew has a standing height of roughly 2.2”-2.6” (5.5-6.5 cm), body width of 1.6”-1.8” (4-4.5 cm), and tail length of 4.1”-5.1” (10.5-13 cm). The typical lifespan of the Northern Smooth-Tailed Treeshrew is between 2-12.5 years.

Common Treeshrew (Tupaia glis)
Comparison drawing of the Common Treeshrew compared to other treeshrews

The Common Treeshrew (Tupaia glis) is very common and adaptable. It is mostly found in Thailand, Malaysia, and Indonesia in deciduous tropical forests. It is considered the largest among treeshrews and resembles a squirrel because of its bushy tail and pointed snout. However, it lacks whiskers which are visible in squirrels. Some common treeshrews are arboreal and others terrestrial, with the former having long tails, short snouts or less developed snouts, while the latter have short tails and long but well-developed snouts. Common treeshrews are monogamous, show unique parental care with two nests for young and parents, and produce a scent for communication or identification of other treeshrews. Besides, they are omnivorous.

The Common Treeshrew has a body length in the range of 6.3”-8.3” (16-21 cm) and total weight of 3.5-6.7 oz (100-190 g). The Common Treeshrew has a standing height of roughly 2.6”-3.5” (6.5-9 cm), body width of 1.8”-2.4” (4.5-6 cm), and tail length of 4.7”-7.5” (12-19 cm). The typical lifespan of the Common Treeshrew is between 2-12.5 years.
