Orangutans

By Hannah

Classification/ Introduction:

Orangutans are warm-blooded mammals. Their scientific name is Pongo. Their family is the Homidae and their species are the P. albelli or P. pygmaeus, there are two species because Orangutans live in two islands, Sumatra and Borneo! These amazing mammals are known as the great man of the forest! They're also the largest tree climbing mammal. Their domain is the Eukarya and their order is the the primates! With arms reaching 2 metres from fingertip to fingertip, orangutans are aptly suited for a life in the trees of Southeast Asia.


Appearance

Borneo orangutans have a smooth,long, orange/red/brown coat, and not much facial hair. Sumatran orangutans however, have a red/ginger coat, and heaps of facial hair. Both types of orangutans have small ears, very pale skin, and a large snout. They have a hand quite similar to a human. Females weigh 30 - 50 kilograms, and males weigh 50 - 90 kilograms. In length, they are 1.25-1.5 metres. Although both Orangutans have many different features, not many people can tell the difference between then when they are together. The Orangutan skeleton is similar to the human skeleton. Their hips, knees and ankle joints are very flexible. Orangutans feet and hands are designed so that they can hang on to branches easily. Currently, Orangutans are only found in Sumatra and Borneo while living in the wild, though fossils have been found in China, Malaysia, Java and Vietnam. Orangutans are kept in other places in zoos.

Diet

Over 400 types of food have been documented as part of the Orangutans diet, and although it consists mainly of fruit, in times of scarcity, Orangutans will shift their eating habits to lower quality food, such as bark, leaves and termites, rather than travel to a different area to get better food. Nearly 90% of the Orangutans diet is composed of fruit.

Although fruit comprises most of the Orangutans diet, they still require other nutrients as part of their daily intake. They receive a mixture of sugars and fats from fruit, carbohydrates from leaves, and protein from nuts.

Behaviour

Orangutans are fully dependent on trees for their existence. They are completely adapted to life in the forest - they sleep in nests, feed predominantly on fruit and travel with ease through the forest canopy, rarely descending to the forest floor. Orangutans are extremely clever, they are man-like and amazing! They are mostly the same as us, but they have hair on nearly every part of they're body! Orangutans have the slowest known life histories of any mammal. They take the longest time to grow up and they are the slowest to reproduce. The female orangutan’s menstrual cycle is 29 to 32 days, with menstruation lasting three to four days.



Habitat

Orangutans are found in Indonesia, on the islands of Sumatra and Borneo. These apes, were once throughout Asia's main land during the Pleistocene. Orangutans prefer a habitat that exist along water ways, and in low lands, because of their high dependence fruit. Biologists have described their habitats as inaccessible, swamp logged and leech-laden tropical forests. The islands of Borneo and Sumatra have vast mountain ranges. Orangutans are rarely seen in elevations that exceed 500 metres. In Sumatra, Orangutans are entirely arboreal because of large predators (such as tigers, leopards) that patrol the forest floor. Borneo contains fewer large predators so males will travel Terrestrially and feed on the ground, but females will remain in the trees because of their smaller size. In traveling through trees, Orangutans have shown intelligence by using common routes and showing the ability to back track to their original route if need be.
