Main Characteristics

Pen-Tailed Tree Shrews have a slender build and a long tail. They have well developed senses of hearing, smell and vision.


Pen-Tailed Tree Shrews can be found in the forests of Indonesia, Malaysia and Thailand.


Pen-Tailed Tree Shrews are omnivores and they feed on a variety of insects, small vertebrates, fruit, nectar and seeds.

They are one of only seven wild animals that are known to consume alcohol. Each night they spend up to 2 hours drinking naturally fermented nectar from the bertam palm. Despite this consumption of alcohol, the Pen-Tailed Tree Shrew does not become intoxicated which suggests that the alcohol is metabolized in a different way than that used by humans.


After a gestation period of approximately 50 days, a litter of 3 - 4 young are born. At birth the young are blind and hairless, but they are able to leave the nest when they are a month old.

Tree Shrews reach sexual maturity at around 4 months old and they generally breed throughout the year with no defined breeding season.


Subspecies of the Pen-Tailed Tree Shrew are:

Ptilocercus lowii continentis
Ptilocercus lowii lowii
