WHY IS THE SIAMANG ABLE TO RUN
• It has very long arms,adapted for movements in trees.
• Their main way of traveling through the rain forest is by
• During brachiation, the siamang hangs from a branch by
one hand while swinging its body around to allow the
other hand to grasp the next handhold.
• Their extra-long arms help them cover up to 10 feet (3
meters) in a single swing.
HOW IS SIAMANG ABLE TO HAVE SUCH
•Siamang have superior strength as it has long, gangling arms
that are longer than their legs.
HOW IS SIAMANG ABLE TO CAMOUFLAGE
•Siamang live among leaves.They’re usually found in the trees at a
height of 80 to100 feet (25 to 30 meters). Their furry bodies are black
making people cannot recognize them.
SOME EXTRAORDINARY TRAITS THAT
SIAMANG HAS :
• Siamang can be twice the size of other gibbons,
reaching 1 m in height, and weighing up to 14kg.
Siamangs’ hands are a lot like ours.
• They have four long fingers and a smaller opposable
thumb. Their feet have five toes like we have, but their
big toe is opposable too.
• One other thing that sets the siamang apart physically
from the other species of gibbons is webbing between
their second and third toes.
• Siamangs can grasp and carry things with both their
hands and their feet. They have a small, round head,
and their arms are longer than their legs. Siamangs
don’t have tails, and they have gray or pink throat
sacs that expands to enhance their distinctive calls -
which can be heard as far as two miles(6.5
kilometers) away.Their throat pouch that balloons
out acts as a resonator to amplify calls.
• WHAT ARE SPECIAL MATERIALS THAT
PARTS OF SIAMANG ARE MADE OF?
• Siamang's two digits on each foot are partially joined
by a membrane—hence it has the name
"syndactylus", from the Ancient Greek word.Siamang
has large gular sac (found in both males and females
of the species), which is a throat pouch that can be
inflated to the size of the siamang's head, allowing the
animal to make loud, resonating calls or songs.
• The siamang also has long, dense, shaggy hair
which is the darkest shade of all gibbons. The ape
has long, gangling arms that are longer than their
legs. The average length of a siamang is 90cm, but
the largest they have ever grown is 1 meter 50 cm.
The face of this large gibbon is mostly hairless
apart from a thin mustache.
Birth of the Siamang
Siamang mates usually stay together for life. They are
fully grown and able to reproduce at 5-7 years old.
Female siamangs are pregnant for about 8 months and
usually have a single baby at a time; twins are rare.
Newborn siamangs have much less hair than adult
siamangs. Babies weigh only about 6 ounces at birth. This
is less than the weight of a cup of water!
• Female siamangs carefully nurture their young. Babies
can grasp their mother's fur to cling to the mother's
belly soon after birth. They are weaned at about 1 year
old. Young siamangs stay with their mother for about 5-
7 years. The young then venture out (or are forced out
by the same-sex parent) to start a new family group of
their own.Siamangs live about 35-40 years.
HOW THE SIAMANGs can
SURVIVE IN THE HOT WEATHER :
• In the dry season, the size of the siamang's daily range
is larger than in the rainy season. The siamang in
southern Sumatra undertakes less foraging than the
siamang in other places because it eats more fruit and
therefore consumes more nutrients, which results in
less time needed for looking for food. Sometimes, the
siamang will spend all of the day in one big fruiting
tree, just moving out when it wants to rest and then
coming back again to fruiting trees.
THE HABITAT OF SIAMANG :
• The siamang inhabits the forest remnants of Sumatra Island and
the Malay Peninsula, and is widely distributed from lowland
forest to montane forest—even a rainforest—and can be found at
altitudes of up to 3800 m.
SIAMANG IN GROUPS
The siamang lives in groups of up to six individuals (four
individuals on average) with an average home range of 23
hectares.Unlike other apes, siamangs and gibbons do not make
"sleeping nests." They simply sleep (alone or with a few
individuals huddled together) in a fork between branches. They
sleep sitting upright, resting on tough pads located on their rear
TWO CHARACTERISTICS :
• Siamang is loyal. As they are one of the few animals known to form
permanent pairs.Siamang mates usually stay together for life. So
we think siamang is very loyal to their partner.
• We choose loyal as one of the characteristics is because we think
loyal is a very important characteristic in todays society.
• Siamang is responsible. As female siamang will carefully
nurture their young and young siamang will be taken care
by their mother for about 5-7 years. So we think the female
siamangs are very responsible for their young.
• We choose responsibility as one of the characteristics is
because responsibility is an value that we need to have in
order to really get people's trust and respect.

-The siamang, as an arboreal primate, absolutely depends on the
forest for existence, so is facing a population decrease due to
habitat loss, poaching and hunting.These illegal activities
devastated the remaining tropical rainforest, especially in
-Siamangs are poached and hunted for the illegal pet trade,
mostly for infant siamangs. Poachers often kill the mothers first,
since siamang females are highly protective of their infants, and it
is difficult to remove the infant without first killing the mother.
Most siamangs on the market are infants, which often die during
The siamang is known to occur in at least ten protected areas: Kerinci
Seblat National Park, Bukit Barisan Selatan National Park, Gunung Leuser
National Park, Way Kambas National Park and West Langkat Reserve in
Indonesia, Fraser's Hill Reserve, Gunong Besout Forest Reserve, Krau
Wildlife Reserve and Ulu Gombak Wildlife Reserve in Malaysia and the
Hala Bala Wildlife Sanctuary in Thailand.

HOW DOES SIAMANG ADAPTED ITSELF FOR SURVIVE :
• Siamangs adapted to life on the tree as they travel through the
rain forests by brachiation.They hangs from a branch by one hand
while swinging its body around to allow the other hand to grasp
the next handhold. Their extra-long arms help them cover up to
10 feet (3 meters) in a single swing. If they’re not swinging
through the trees, they’re very likely walking along branches with
their arms outstretched to help them keep their balance.
• The siamangs in southern Sumatra adapted to hot
weather better than the siamang in other places
because it eats more fruit and therefore consumes
more nutrients, which results in less time needed for
looking for food. Sometimes, the siamang will spend
all of the day in one big fruiting tree, just moving out
when it wants to rest and then coming back again to

- This learning trip to the zoo has helped our group members to know more
about the animal that we research on. ~HANISAH
- We think that this learning trip is very useful as we really
learned a lot of new things from it. ~ MEINI
-By doing this science
project,we have learned how to do Internet research.
-At first we don’t have confidence to finish this project as
we did not find out much information about siamangs in the zoo.
~GERALDINE -Then,we try to find information
about siamangs on the internet.In the end,we managed to finish this project on
time by using the informations from the internet and our own explanations.
~HAZWAN -So we think this
project is beneficial as it did not only helped us to learn more about
siamangs,it also helped us to learn how to do internet reasearch.
