The extant primate species I decided to research is the Golden Snub-Nosed Monkey, scientifically known as Rhinopithecus roxellana. Part of the reason I chose this species was how odd it looks next to other primate species; it has a flat blue face, big lips, and bright orange color. The other reason I chose the species was because I read that it is now an endangered species and was curious about why it has become endangered and how people are trying to change that. I believe it is important to study the golden snub-nosed monkey because looking at how they interact with their environment and with each other may give us a look into how early human ancestors may have acted under similar conditions. Before I get too far into the specifics of my primate I should discuss how it is different from modern humans. A couple of ways that the two species differ are in appearance and dentition. Appearance is probably the biggest way we differ from the golden …show more content…
The golden snub-nosed monkey will vary in appearance depending on the sex of the monkey you are referring to. Like in some species of birds or other primates the females are less extravagant looking and this is also true in the case of the golden snub-nosed monkeys; the females have silvery backs and brownish-black head and upper extremities. However, the males have the bright orangey gold color, that gives this species its name, on their head, forehead, neck, and upper parts. (Richardson, 2005) Another characteristic of the species is its smushed in forward facing nostrils. Along with having the smushed nose this species has a light blue face and the adult males develop wart-like growths in the corners of their mouths. Not only do the males and females differ in looks, they also differ in size due to sexual dimorphism; the males on average are around 6 inches longer and 14 lbs heavier. (Gron,

DESCRIPTION: The Cotton-top Tamarin (aka saguinus Oedipus), also known as the Cotton-headed Tamarin or the white-plumed bare-faced Tamarin, is a rather small, furry, monkey-like mammal that is identified by ecologists through the distinct lengthy, white hairs on their heads. According to the Primate Info Net Website, a reliable source that is run by the Wisconsin National Primate Research Center and maintained by the Lawrence Jacobsen Library staff (both located in the University of Wisconsin-Madison), “the average height of both males and females is 232 mm (9.13 in)”. In addition, they also state “wild males and females weigh between 410 and 450 g (14.5 and 15.9 oz) but average 416.5 g (14.7 oz), while captive cotton-top tamarins are significantly heavier and weigh, on average, 565.7 g (19.9 oz)” (Lang, 2005).
The order of primates include a wide and varied array of species, from lemurs to macaques to humans. Grouped by distinctive characterestics, they are also distinguished by clear dissimilarities. Both these aspects may be seen with comparison to chimpanzees and bonobos and to an even more marked degree in regards to nonhuman primates and humans. Each species possess its own specific traits ranging from physical to behavioral to mental that set it apart from its biological kindred while still being firmly linked together. Chimpanzees and bonobos are physically quite similar to one another, with the chimps displaying greater sexual dimorphism, the physical variances between males and females.
They still have functional ears but its inner and not external like other seals. Thier hairs are short and have a dense undercoat, they can have a variety of colors. For example they come in light gray with silver dark spots, black , red , dark gray, or brown with white rings. They are mostly covered in spots and it comes in all sizes big or small. When they are pups their colors are usually in solid light gray, black, red , dark gray, or brown.
The physical nature of a primate body as wells as its movement is a unique factor in the animal kingdom. There has been continuous change through locomotion and body configuration throughout each grades of primate evolution. In this essay I will be discussing the modifications in time as well as theories in each grade of primate. This research paper will try to elaborate on the evolutionary modifications and some of the theories that have been proposed for these changes throughout our and other primate evolution. With time primates development was due to environmental changes.
“Non-human primates, due to their level of intelligence when compared to other animals, and also due to their evolutionary closeness to man are maintained in several types of captive facilities like laboratories, zoological parks, animal circuses and conservation breeding centres” (Mallapur 2005). They are kept for observation and studies but many of these captive conditions evoke abnormal behavior patterns among non-human primates. Maintaining a satisfied non-human primate in captivity can be challenging. They are many important variables to take into consideration. When the enclosure does not suit the needs of a nonhuman primate it can affect their behavior physically and psychologically.
Head and body lengths of adults average from 9.7 cm-13.2 cm. However, in the wild the average is much higher at 24.3 cm in males and 23.0 cm in females. Many species are sexually dimorphic, which means the males are larger than the females. Tarsier have a particular spinal morphology that allows them to turn their heads a whopping 180° in each direction. Their legs and their muscles make up about a quarter of their total body weight.
The ring-tailed lemur has long, black and white ringed tail and the lack of a large brain. It is endemic to the island of Madagascar. The ring-tailed lemur is highly social and female dominant. Its average weight is 4.9lb and its head to body length ranges between 39 and 46cm (Wikipedia). Its tail is longer than its body and is not prehensile.
Thesis: In The Monkey's Paw by W.W Jacobs, the realistic essence of the monkey's paw made it fundamentally creepy. Point 1: The monkey's paw is a symbol for inclination for greed, exposing our superior wants as people, even the most humble. Point 2: Consequences for the actions of those using the paw develops the image of regret and fear. Point 3:
Regarding this, the studies conducted by Schultz counted long dark terminal hairs and not the fine transparent vellus hairs. With the number of follicles in the skin being determined during the formation of the fetus, the number of hairs on the mammal is determined at birth. When the animal grows the larger ones gain more spacing between the hair follicles and the density decreases with the increased size (Sandel,
