The Key Features Of The Orangutans

The Squirrel Monkeys live in rainforests.Squirrel Monkeys are the most abundant primate in riverside forests in the Guianas and Amazon River basin. The most common Squirrel Monkeys have olive or greyish crowns, they are only found in South America. They are usually in the trees, but every once in awhile they will come down to ground. They live in tropical forests in south and

I primarily observed three orangutans, one male, one female, and one juvenile, of Sumatran and Bornean descent, scientifically known as Pongo abelli and Pongo pygmaeus, respectively, and to a lesser extent, two gibbons known as siamangs, or Symphalangus syndactylus. These primates share the same enclosure in the San Diego Zoo in California. I observed the orangutans from 12:58 P.M. to 2:00 P.M. CST on September 19th. During this time frame, the three orangutans mainly stayed high up in their man-made structures, consisting of multiple metal bars covered with nets, ropes, and hammocks. The female and juvenile orangutans stayed above ground from 12:58 P.M. to 1:31 P.M., and again from 1:48 P.M. until 2:00 P.M, approximately 45 minutes. During

Primate conservation has long been a topic of debate, reliant most heavily on the struggle to provide the necessary resources to combat the declining rate of population growth among various species. Orangutans in particular, both Sumatran and Bornean, have experienced a rapid drop in their free-living populations. With an estimate of only 27,000 left in the wild, questions have been raised over what selective pressures are impacting the steady decline of these animals existence. While hunting and poaching have been identified as contributing factors, habitat loss primarily takes center stage in their demise. Conservation efforts have been made and continue to be somewhat successful, however, challenges and set backs continue to threaten

Gentle, peaceful & shy are the words that describe gorillas. Gorillas in the mountains & eastern lowland areas are totally vegetarian & eat leaves, fruits, & stems like bamboo. On the other hand, gorillas in the Western lowlands eat small invertebrates & insects apart from plants. It’s anticipated that approximately 80% of gorilla population’s extinct, because of the destruction of their habitat, humans hunting them down & diseases as a result of Ebola

Orangutans (Figure 3) are our first cousins since they share 97 percent of our genetic material. Contrary to other apes, orangutans are semi solitary which is unique in its social organization (3). Adult males which are the most solitary, and they associate with only their current, former, and potential consorts. For the semi-solitary orangutans, the only playmate is its mother. Even female adults are more social than male ones, rarely they groom, touch, hold hands, chase, or fight. On rare occasions, female adults may groom; however, it lasts only few seconds. Sometimes, female adults meet and travel with one another to express the close relationship. The long call by a male orangutan expresses an alert to others about his presence. Usually, other orangutans only react if the call is close by or aggressive towards them. Male orangutan can use vocalization to express that he is angry and frustrated, and that call signals a threat to another male (3). Female orangutans also produce vocalization when they get upset by the presence of another male.

Primates have some features that support them for the arboreal life. First, primates have developed grasping extremities with the divergent hallux and nails instead of claws. These features help them grasping branches better. Second, primates have enhanced vision with the optic convergence, which helps them look straightforward. They also have postorbital bar to protect the eyes. Third, primates reduced the olfaction that is not useful for arboreal life. Fourth, comparing to the other mammals, primates have large brain consider to the body size. The large brain helps them to process the complicating reactions, and thinking. Haplorrhines primates have some unique derived traits: the loss of tapetum lucidum, which enhances the vision in the darkness; and haplorhini, which is dry external nose. The anthropoid primates have developed some derived traits. They have postorbital bar with closure, and this makes a complete bony ring surrounds the eyes. They also have fused mandibular symphysis. The Platyrrhines have the dental formula 2.1.3.3/2.1.3.3. The Catarrhines have dental formula 2.1.2.3/2.1.2.3. The Cercopithecoids have the bilophodont molars to enhance the chewing ability. The hominoids are the most developed primates, which have some derived unique traits. They have larger brain, loss of tail, longer arms than legs, broad thorax with more muscles, and highly mobile shoulder.

Introduction This first lecture is designed to introduce the primate order in terms of its classification and to familiarise you with the animals so that the rest of the course makes some sort of sense. I will cover a working definition of what makes a primate, give you a general classification scheme, describe the major features that identify the groups within the classification and discuss some of the controversial areas of the classification. I shall treat the taxonomy as a synonym for classification which seems to be its commonest current usage, although you should be aware that some people consider taxonomy to be more about the principles behind the classification than the classification itself.

The teeth of a gorilla have high crests that are used to help break down leaves that make up a large proportion of their diet. This species has relatively long forelimbs and short hindlimbs. The gorillas have a short trunk and wide pelvis. Individual gorillas can be distinguished from the nose; each gorilla has a unique nose pattern, like the human fingerprint.

My observation of the orangutan habitat was on a sunny and hot day with the average temperature being between 65-70F. The Enclosure for the orangutans was a grassy and dirt area that was approximately 35ft+ in width and about 75ft+ in length with a long glass barrier for observation. The habitat featured three 15ft tall fake trees which were fashioned after a tree but bare of leaves. The trees were

Primate life on earth began about 50-55 million years ago during the Eocene Epoch, although it is unknown how many different living species of primates there on earth. One likely fact is that the major groups of primates have been discovered, two of who are the Pongo Orangutan and the Pan Paniscus Bonobo. The word Orangutan translated from Malay means “Person of the forest” this is so because there are only two places you can find an Orangutan’s: Malaysia and Indonesia. The orangutan is an official state animal of Sabah in Malaysia. There are two different types of Orangutan’s; the Bornean Orangutan, which found on the island of Borneo and the Sumatran Orangutan, which is found on the Sumatra Island. Orangutans are known as the world’s largest tree climbing mammals, unlike other primates they spend the majority of their lives on trees. Orangutan habitat consists of primary tropical rain forest and old secondary forest at low elevations. Orangutans prefer high-density climate due to their diet, which consists 65% of fruit. Bonobos have been considered humankind’s closest relative and share 98% of our DNA. Bonobos can only be found in one country: the Democratic Republic of the Congo also known as DRC. Bonobos inhabit the second largest rainforest on earth, the Congo Basin. Bonobos prefer swampy rainforests and similar to the Orangutans, Bonobos are arboreal which are adapted to living on

Primates come from the order of mammals and are defined based on the morphology of the group of animals. Morphology is the branch of biology that concerns the study of the structures and forms of various organisms based on their structural features. The study involves both the internal and external primary functions of the structures of an organism including the parts. According to the identification of primate’s family they are divided based on the generalized and the specialized features of the organisms (Russell 2015). The generalized features of the organisms are the common traits that identify the organisms to the specific family of primates. These are the characteristics that the entire organism that is considered to be primates possess

This book included a large section of information on orangutans with observations about basic traits as well as mechanical and social behaviors. It is interesting to note that the section also notes the various methods these orangutans were being hunted, killed or used by its enemies. It concludes describing an old misconception of how an orangutan’s “great strength and ferocity render them dangerous.” We now know that these animals are actually very rarely aggressive, but rather solitary social creatures. The common theme of primates being dangerous and monsters can be across various historical writings.

The orangutans differ in hand size, Herald had much larger hands than my own and Taylor’s hand size was around the same size as mine. Their hands display the thickness of the fingers and knuckles, which is more likely explained by their fist walking attributes.

Their lives are declining due to lodging, farming, etc. Their population has declined more than 50 percent during the last decade. Orangutans have great physical characteristics, they are the largest tree-dwelling mammal, their also known to have similar characteristics of us, humans and they’re highly intelligent in general. These primates also have great color vision, have opposable thumbs, big toes, and grasping hands. What caught my attention a lot is their hair color, it’s a brownish reddish color making it look a bit orange, and that is when I stood focus on this certain primate. Also, what caught my attention was how I was looking at one of them sitting down minding her own business and then other one come and sits right beside her and begins bugging her, for example touching her, pushing her a bit in the shoulder. Kind of when you tell someone that is feeling down, hey cheer up and push them a bit in their shoulder. The monkey would not do anything back, basically letting herself which I though was pretty cool because if someone were to be bugging me like that I would probably get a bit ticked off or react and say something. A reaction completely different then this Orangutan, I would say she’s really humbled, but that is just my perspective at that moment I would not actually know, unless I were staff. Although at the moment I seen another monkeys go and sit next to her does not mean they are always together.

Apes and primates come in all different shapes and sizes. They all exhibit different characteristics and most importantly different behaviors that separate these different primates. The thing that is the most fascinating is really how similar they are to us. The similarities go past structure, similarities can also be seen in their behavior and how they think similar to a rational human being. Gorillas are the biggest primate currently alive on earth and they are also one of the smartest as seen through Koko the gorilla who actually understands english and can effectively use sign language. Gorillas are truly fascinating creatures that exhibit behaviors
