One of the most interesting primates living on this earth is the Siamang gibbon. I first found these primates interesting while I was at the Lincoln Park Zoo in Chicago years ago because of their unique sound they make with their giant throats that sounds like a howl but has rhythm like a song. They have distinct features unlike other gibbons and they sure know how to make a scene or at least noticeable to visitors. Although my visit was very vague, these primates are still imprinted in my memory.…
The New World monkeys (Platyrrhines) can be divided into two families: the Cebidae and the Callitrichidae (the Callimico is also a Platyrrhine and shares many of the characteristics of the callichitrids, but the position of the Callimico within the Platyrrhines will not be considered here). The Callitrichidae family includes the marmosets and the…
Wolf’s Guenons, Old World monkeys, are found at south of Africa’s Congo River. Their habitat is forests, woodlands, near rivers and streams. They have a unique way of jumping from tree to tree: they aim at the center of dense clump of foliage and leap. When they land, they scramble through the branches and find a large, steady limb, and then hurl themselves at the next clump of foliage from there. Like many other guenons, their smaller body size allows them to forage farther out on small branches and escape leopards and chimpanzees by fleeing to the outer edge. This colorful species of monkey has nothing to do with a wolf. It was named after the last name of the person who discovered it. Like other guenons, Wolf’s Guenons love to eat fruit. Other favorites include leaves, plant nectars, and insects. All guenons have cheek pouches they can store food in as they forage. Wolf’s Guenons may live with other related species in small social groups. They have been seen in Africa living with red-tailed monkeys, black Mangabeys, and black-and-white Colobus monkeys. This species status is vulnerable due to destruction of forest habitat for agriculture and logging, excessive hunting for food, and illegal bushmeat trade. Mandrills, endangered monkeys from Africa, are one of the largest and most colorful monkeys in the world. Male mandrills that sport the brightest and most distinctive reds, blues, lavenders, and golds on their faces and fur are thought to be most attractive to females. Their bright colors also play a role in keeping the troop together as they travel in the forest. Mandrill troops contain one dominant male, several females, and their offspring, usually about 20 animals. Super troops of several hundred may gather where food is plentiful. Mandrills come equipped with their own…
The Allen’s Swamp Monkey is a “strong, stocky primate” covered in a gray and greenish fur. The toes and fingers of the monkey are webbed which allows them to swim well. The males are usually larger than the females and they are really active primates. Their origins can be traced from the Congo Basin to western Zaire. The habitat of the monkeys is limited to swamp forests. In behavior they are mostly active during the day and are tree-dwellers. Their diet consists of fruits, leaves, fish and insects. Little is known about their reproduction but it is said that females bear young for three months and they are mature after three to five years. Common predators include raptors, snakes, and bonobo, however, swamp monkeys can dive into water to avoid them. Swamp…
Some of the worlds’ smallest primates are committing suicide at alarming rates. Are their deaths due to chemical imbalances in the Tarsiers brains, or are there other contributing factors. This paper will explore possible explanations on the Tarsiers’ declining population rates. Several reasons will be proposed to the causes leading to why the Tarsiers may become extinction. Several ways to help prevent the unnatural extinction of these primates will be discussed. Things such as, putting a stop to the loss of their natural habitat, being a food source for humans and the financial gain from exploiting the Tarsiers will be covered.…
Capuchins have traditionally been in the genus, Cebus Erxleben from the family Cabidae. There had been four species recognized among the capuchins, such as: Cebus albifrons, Cebus olivaceus, Cebus capucinus, and Cebus apella, all of which are a taxonomy that dominated capuchin history for an approximation of 50 years (Lynch Alfaro et al., 2014). Over the years more capuchins had been recognized as well such as, Cebus kaapori, Cebus libidinosus, Cebus nigritus, Cebus queirozi, and finally Cebus xanthosternos. In a physical sense, capuchin monkeys weigh around six to twelve pounds and live over five decades. In contrast to New World Monkeys, they have robust jaw and dental structures, large brains…
The taxonomic classification of the primate that I observed at the Santa Ana zoo was the Crested Capuchin or (Cebus paella robustus), Family: Cebidae. It is a new world monkey…
With a variety of new world monkeys, the capuchin monkeys have their own characteristics that differentiate them from others. The capuchins are apart of the superfamily of Ceboidea and from there branch out into the family Cebidae. They are mainly distributed in tropical and subtropical regions in Central and South America(). In these tropical areas the habitats that capuchins can be found in range from deep rainforest to dry forest with a height elevation from sea level to 2700 meters high(). Capuchin are omnivorous and their diet consist mainly of fruits, insects, nuts, and seed. In size,animals in the Cebidae family are normally small, like the capuchins who can have a mass from 1.1 to 3.3 kg and a length of 32 to 56 cm(). Normally the male capuchin monkeys are bigger than the females and also have distinct differences in the proportions of the head compared to the body. However in the Cebidae family, the capuchin monkeys are the only ones with a grasping tail which is mainly used to help keep balance and hardly ever use it to grab object(). They are indeed arboreal and do arm swing on trees. Capuchins also have opposable thumbs. The color of their fur can range from white to brown to black. Capuchins have…
These gibbons are commonly found in the rain forests of Southeast Asia (Golden-Cheeked Gibbon plaque, 2018). Although they are heavily arboreal, they do not possess a tail nor a prehensile tail. There does not seem to be any sexual dimorphism present amongst the male and female. Their form of locomotion is brachiation which means they rely on their upper limbs to move from tree limb to tree limb. The cage at the zoo consisted of only two adult individuals.…
I thought that this question was very interesting because primates are the closest living relatives to humans. Primates are fascinating because they resemble a primitive or basal version of ourselves and at the same time are also quite different from us as well. There is a large number of primate species both in the African and Asian continents as well as in the Americas. Those species that are found in Africa and Asia are collectively called old world monkeys and apes. The species found in the Americas are known as new world monkeys. An interesting feature that many of the new world monkeys have that old world monkeys do not is a prehensile tail which can be used as a fifth limb. Another interesting difference is that thanks in part to their prehensile tails the new world monkeys are almost entirely arboreal while the old world monkeys are both terrestrial and arboreal.…
The first type of primate I observed was a Bolivian Grey Titi Monkey which is a type of new world monkey species found in areas of eastern Bolivia and also can be found in Brazil. The scientific term for this species is Callicebus donacophilus. These types of monkeys have medium sized body structures and do not exhibit sexual dimorphism between male and females. The Grey titi monkey is diurnal making them mostly active during the day. They are also arboreal, which means that this species spends most of its life living in the trees. I noticed that this type of monkey is able to travel around on the ground and move throughout the trees very quickly. Since they are able to move around so quickly and have a sustainable life in the trees, I think that is how they avoid potential predators or larger animals that would be a threat on lower levels. The form of locomotion that they mostly use is walking, using all four limbs to support their bodies, which makes them quadralpedlic. Their diet primarily contains of fruits, leaves and insects that they forage by searching on the ground and using their hands to reach in the trees to obtain it. There is a strong bond between adults mating pairs. Evidence of the bond was observed through their behavior and proximity of the pair, while resting on a branch, I observed the pair with their tails intertwined with one another. When separated to communicate within the small range of their cage, I noticed that both used high pitch squeaks to call and find their partner. While observing…
The first primate that I observed was the white-cheeked gibbons. They are also known as Nomascus leucogenys and they can be found in canopies in subtropical rainforests. White-cheeked gibbons…
The order of Primates is comprised of an estimated 230-270 species, however, new species are being discovered every year and some scientists classify them using sub-specie groups, which makes it difficult to count an exact number of primate species in existence today. Most primates are found in tropical or subtropical regions of the world, but have never existed in Australia or most of the islands of the Pacific. Most primates are arboreal, meaning that they live in trees. Humans and gorillas are two species that are primarily terrestrial. Most primates are also diurnal, meaning they are active throughout hours of daylight and then sleep at night. They are also omnivorous and generalists, meaning that they will eat almost anything. This…
Of all the horror short stories I have read “The Monkey’s Paw” by W.W Jacobs is by far the best for creating a suspenseful atmosphere/mood. I intend to show how W.W Jacobs creates this suspenseful atmosphere/mood through the analysis of setting, narrative, dialogue and character in order to deepen my understanding.…
