Orangutans
Orangutans are the largest tree-dwelling animal in the world. Males usually weigh about 90 kg, while females range from 30-50. Orangutans are a red/orange color. Their arms are a lot longer than their legs. They have 2 m long arms, so they could touch the ground if they were standing on 2 legs.
There are two types of male orangutans. There is a flanged and an unflanged. Flanged male orangutans have large, flat cheeks that are very wide. These special cheeks are called flangs, thus, giving it the name. Flanged orangutans have a throat sac that vibrates, which allows these orangutans to make a “long call”. Flanged orangutans also have a dark-brown layer of hair on their back. Flanged orangutans aren’t always displaying their flangs, for reasons unknown, they can change hide their flangs to look unflanged. Unflanged orangutans don’t have flangs, so they look like a normal adult female orangutan. …show more content…
They are the gardeners of the forest. They disperse seeds throughout the forest, which is important for humans, tigers, elephants and rhinos. So orangutans are some of the most important animals for the ecosystem in the world. There are two species of orangutans. There are Bornean and Sumatran, which only differ a little in behavior and color. They both have thick hair, but Sumatran have longer facial hair. Sumatran are also more social than Borneans. Sumatrans are found a lot more in the trees. The Males very rarely seen on the ground, and females pretty much never touch the ground, whereas Borneans touch the ground much more
