Mandrill Vs Gibbon Essay

As part of the only Old World Monkey group I analyzed the Silver Langur whose scientific name is Trachypitneus Cristatus. In this cage there was a total of 6 monkeys so there was very much activity. This

Primates are one of the most interesting mammals on earth, not only because of their complex social structures, but because they hold so many similar characteristics to humans. Primates are often cited as our closest living relatives and on two separate occasions I observed four separate species of primates at the San Diego Zoo that can justify their use of their physical characteristics and behaviors that may be similar as well as different to the other primates and ours.

These people have given detail of its features and characteristics. Bigfoot is described to have a rancid odor which is smelt from miles away. It can weight up to 1,000 pounds and it reach higher than eight feet in length (Gaffron, 16). Its footprints tell a lot about Bigfoot as well, from them scientists deduce his extremely wide strides of six to eight feet, the four inch to 24 inch foot size, and the unusual disproportionate width of the ball of its feet (Fahrenbach). With all its obvious differences Bigfoot also shares common traits with primates, for example the hair some bone structure, and a minimum mental capacity.

Within this essay, we will study more in depth the behavioral as well as physical traits of two primates at a zoo from their interaction with their peers to their place in the group. This observation would enable us to further understand the possible existing correlation between humans and primates. First, I studied a female chimpanzee with her baby, and then, a dominant male gorilla, in San Francisco Zoo at about noon, on May 23, 2015, for an hour each. Even though they share some similarities such as having a large brain, living for a long time, and being bored in their enclosure, they are still different; when gorillas are the largest, chimpanzees are the smartest. In fact, chimps use tools to catch food, they would not be able to reach

Isbell and Wright’s articles both focus on monkey species and their native environments, Africa for Isbell’s (1994) vervet Old World monkey and South America, Peru area, for Wright’s (1994) owl and titis monkeys. The articles main focus is the relationship between these monkeys and their natural predators. Focusing on how the predator aspect of their lives is determined by their environment and adaptations they make to ensure survival. Isbell’s Vervets Year of Doom focuses more on the adaptations that was forced upon the vervets’ because of their changing environment, the death of fever trees. While Wright’s Night Watch on the Amazon focusses more on how the primates way of life affects their relationship with predators and the likelihood of attacks. Both articles have similar aspects however the species way of life, specifically their environment and sleep schedule, are quite different as well as the authors way of observing and studying the primates within their habitats.

According to van Roosmalen (1985), it is a hypothesized that dominant female spider monkeys lead the group to food sources, suggesting why there may be a difference in these animals due to their ecology. As there is only one study to date about spider monkey color vision and it was based on one male and one female monkey, this study will add to our knowledge about whether spider monkeys have similar

This paper aims to study the traits of non-human primates. By observing two types of primates including Common Squirrel Monkey (Saimiri sciureus) and Western Gorillas (Gorilla Gorillas), I try to find out their characteristics, pattern of their behavior, and differences between these two primate species. Especially, characteristics and behavior such as social interaction, food acquisition and intelligence will be discussed and compared in this paper. In order to enhance the persuasiveness of my observation, I recorded and examined at least 25 distinct characteristics of both Common Squirrel Monkeys and Western Gorillas. It is also helpful for me to compare these two primates. Apart from exploring the primates’ traits and differentiation between them, this paper will discuss the effects of captivity. How being in captivity and on display in a zoo would influence their behaviors and emotions? The observation was a great success and I have successfully derived with a hypothesis base on our observing data. The ultimate goal of this paper is arousing humans’ awareness of the importance of studying primates.

According to Wikipedia, spider monkeys tend to live in medium sized groups of around two or three dozen individuals called troops, averaging at about 15 to 25 individuals in a group. The group will break up into smaller bands on occasion, like to split up to forage for food resources or if there are not enough resources to support the entire group to increase their chances of survival. They are typically found in large, unoccupied areas in the upper layer of the rainforests of Central and South America but can also be found in Mexico. They are primarily arboreal, meaning the spend most of their time swinging from trees, using their prehensile tails to move around. They use their tail as a fifth hand using it to help them

Pointed head, a unique anatomical characteristic of the Gorilla. This is attributed in the adult male to a prominent sagittal crest overlaid with a pad of fibro fatty tissue. This characteristic is less pronounced in females and smaller bodied adult males. Extreme muscularity. Broad, flat face. Jaw that protrudes beyond the nose. This anatomical feature (prognathism) is distinctly ape-like. Prognathism is due to the need for large jaws and teeth for mastication. Brow-ridges, above the eyes is a huge shelf of bone. Hair color is most often described as light brown, dark brown or black. Other colors that have been reported are grey, light, white, silver-tipped, and red to reddish-brown. Hair length is longer on the head, shoulders, and arms, than anywhere else on the body. Hair distribution, body is completely hair covered except for patches of bare black skin on the face, chest, soles of feet, and palms of hands. There have been reported attacks on humans but they cannot be proved. Stories of an ape like creature roaming the forests of North America have been around as long as some of the Native Americans tribes started in certain areas, due to the finding of cave painting of sasquatches. However, the earliest written account was made in 1811.

I chose to write my paper on the differences between diurnal and nocturnal primates. I chose this topic because I thought it sounded interesting. I also chose it because I have horrible night vision and have trouble driving at night, so I thought it would be cool to learn how certain primates live in darkness and how their eyes work. This topic is relevant to biological anthropology because we learned about all different types of primates throughout the course and their characteristics including: social behaviors, diets, nocturnal vs. diurnal, and many other aspects of primate life. We didn’t get to go into detail about many of the primates and see the differences in nocturnal versus diurnal. In my paper I decided to key in on two specific animals, the owl money and brown lemur. I did this because I wanted to get to know more about each animal and the owl monkey has a very unique story. I also chose to narrow in on the main difference between all diurnal and nocturnal animals and that is the eyes. In my paper I will talk about the behavioral differences between the owl monkey and brown lemur (I will also go into some detail about each of the primates, because I thought they both were fascinating), the differences in the eyes, and also just some other general facts about diurnal and nocturnal primates.

The second grade of primates evolved about 53 million years ago, in Eocene epoch. There are five tarsier species that all live in the islands of Southeast Asia, where they inhabit from tropical forest to backyard gardens (Jurmain, et al, 2011). They are considered to be closely related to lemurs and lorises (prosimian family) for the several traits that they share with Grade I primates while having some anthropoid features as well. However, tarsiers have distinctive characteristics that isolate them from other primates. They are categorized as the smallest creatures among the primate species and they are well known for their enormous eyes which is as large as its brain. They are normally nocturnal insectivores but sometimes carnivorous. They catch insects by jumping at them and as they jump from tree to tree, they even hunt for birds while in motion.

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.

During my research of Orangutans and Mandrills I observed them in captivity at the San Diego Zoo. My observations included a 20 minute observation of each primate as it cohabitated with other Primates and with other members of its own species. My findings will support the research of Orangutans and Mandrills through firsthand observations.

On Friday, March 31, a observation study was conducted at the L.A. Zoo. The time of arrival for the observation was at 11:48 am and the end of the observation was at 2:42 pm. The weather condition at the zoo was very sunny with a mild gust of wind every so often, which is a perfect weather condition to conduct a study. The main reason for conducting this observation study was to study and gather information about the many different types of primate that are located at the zoo. To see how different or similar each primate is to one anotherin different aspects.
