generic name derives from the Malaysian word "tupai" meaning
squirrel. The Treeshrew has a longer nose and no long black
whiskers like squirrels. It differs from other genera of
Treeshrews as it has a tail covered with long hairs, a squared
off patch of naked skin above the nose, and lower earlobe
which is smaller than the top of the ear. The head and body
length of tupai averages between 140 - 230 mm, and the tail
is a little more than the length of the head and body. Weights
range from 100-300 grams. Colors of the upper parts vary
from ochre, reddish, olive or shades of brown and gray to
almost black. Underparts are whitish to buff or dark brown.
And there is sometimes a light shoulder stripe. There is
a throat gland present in Tupaia glis which differs
from the glands in primates, but occurs in some insectivores.
Treeshrews are diurnal. They spend much of their time on
the ground and in bushes. They are always searching for
food, mainly insects. They also eat fruits, seeds and leaves.
When eating, they sit on their haunches and hold the food
between their front paws.
Social groups consist of one dominant male with 1-3 females.
Territories are well established with ranges of opposite
sexes overlapping freely. Breeding appears to occur throughout
the year. Nests are built in the hollows of trees. Estrous
lasts from 8-39 days with gestations of between 40-52 days.
Litter sizes range from 1 to 3 young who are kept in a separate
"juvenile nesTupaia" The mother visits the infants to feed
them until they are weaned at about 36 days. They then move
to the "parental nesTupaia". Sexual maturity is achieved
at about 3 months in both sexes.
Tupaia glis is found in SE Asia, south of about 10º
N latitude, from the vicinity of Hat-Yai, S Thailand through
mainland Malaysia (and adjacent coastal isls) to Singapore;
also Indonesia, including Siberut, Batu Isls, Sumatra, Java,
Bangka, and the Riau, Lingga, and Anambas Isls.
