Orangutans

By Toby

Introduction

The scientific name for the Orangutan is Pongo. They are critically endangered and are extremely smart. These stunning Orangutans are the largest arboreal animal which means "live in trees". The population of these dying creatures is 40,000, 5 die every year!


Appearance

The Orangutans have beautiful orange hair all over their body. Adult males stand from 1.25 to 1-50m tall while females are only 1m tall. Adult males weigh from 50 to 90kg and females only weigh from 30 to 50kg! Although they are not as strong as the beastly gorillas, Orangutans are seven times stronger that humans! The huge arm span of these creatures is 2.13m wide. The built muscles on these Orangutans enable them to be able to swing from tree to tree.


Habitat

The glorious forest of Sumatra and Borneo in Indonesia is where these Ornagutans live day and night. In the morning they start to build their nests which are usually about 30m high, where they will sleep at night and in the day sometimes for an afternoon nap. You can tell if the nest is fresh or old because the frsh ones are still green but the old ones are brown and old looking. Already they have lost 40% of they're forest due to palm tree plantations which provides nothing for these Orngutans.


Diet

These amazing Orangutans diet consists of 90% fruit but their favourite fruit are figs. These georgious creatures can survive on a starvation diet which consists of bark and leaves for 3-4 weeks! They spend about 6 hours a day foreging for food and they eat about 400 different plant species.


Life Cycle

When a baby Orangutan is born it has huge eyes and can hardly even lift their heads without their mother's help, they are completely dependant on their mothers. The mothers are pregnant for about 8 and a half months which is very similar to the human. The Orangutan mother stays with the baby for about 8 years.



Behaviour

Orangutans are extremely smart and are able to imitate the humans with every day activity. The strong Orangutans avoid meeting with other males because it is trouble if there is a fight. When the males do meet they have threatening calls to scare of the enemy such as staring, inflating their throat pouches, long calls and shaking branches.

Threats

There is one main word to explain why these Orangutans are dyeing, deforestation. People are constantly chopping down trees and instead, planting palm oil plants which provide absolutely no food for the Orangutans.
