Physiological and psychological traits of two primates Assignment

Physiological and psychological traits of two primates - Assignment Example Physiological and psychological traits of two primates This observational activity was conducted in Fort Worth Zoo in Texas during which physiological and psychological traits of two primates were studied and compared. However, body hairs were not visible on the face, hands and feet of this animal. He also had silver grey hair as well on his bak which showed that this gorilla was in his late 20s. Same hair color was visible on its thighs and chest as well. The weight mentioned on the board was 40 kg which is fairly regular for this genus. Average height was supposed to be around 65 inches. There were three more gorillas kept in the same setting however major focus of this session was on the male Gorilla who appeared to be the leader of the herd and had a silver back. An interesting fact about the outlook of this gorilla was his lower jaw protruding the upper one. This particular primate was kept in an open area which had concrete floor as well as grassy area. However, the animal appeared more comfortable on the grassy land. He was being fed with bananas and other fruits whereas he was also occasionally picking grass and chewing it. There were some big insects visible on the grassy land which were picked by Gorilla and taken into his mouth. The Gorilla had its arms longer than legs and was moving on four limbs with major support given by the hands with curled digits. The male Gorilla did not appeared to be interested in interacting with the visitors and was showing less receptiveness to the food given or noises made by them. Throughout the observation, a single instance of low growling sound made towards the visitors was witnessed. The gorilla had made a small nest of plants and shrubs which he was using for occasional sitting. The weather on the day of visit was sunny and subject being studied appeared to enjoy sunlight. However, he kept on moving between shadows made by artificial rocky walls and open ground. Another interesting observation made was about little interest shown by Silver back gorilla regarding acti vities taking place in its habitat. Rest of the gorillas who appeared as female due to their smaller height and weight were roaming around freely towards food provided by zoo employees however they were just interested in food supply and not the individual feeding them. Unlike them, male gorilla only moved towards food once other gorillas had taken their share. Furthermore, he was picking up fruits thrown by some children. Some of the edible items were removed by zoo members and they were also told not to throw food inside gorilla’s habitat. The male Gorilla also appeared a little offended due to noise made by visitors to attract a smaller gorilla that seem to be attracted by the food offered by visitors. Therefore, when the smaller gorilla tried to move towards walls of its living arena in order to get closer to the visitors, the male Gorilla who was the subject of this activity quickly made a forceful growl in order to warn him. This production of sound was further followed by few quick leaps as well. Later on, the smaller Gorilla was taken to the nest of shoots where it was handed over to other female Gorillas. It was also noticed that the male Gorilla was paying relatively no attention to the water reservoir present in its living area. Although he moved towards it several times but did not touch the container with its mouth. On the contrary, he dipped his hands in the container and then put them in his mouth which quenched his thirst for the time being apparently. Perhaps, the reason for such low consumption of water is high use of vegetation which already has sufficient percentage of water. Male Mandrill Another subject
