Rhesus Monkey vs Uakari
Rhesus monkey and uakari are two of the most striking monkeys with many important differences exhibited between them. However, there are instances with some inconsistencies among people about the characteristics and the importance of these animals. Therefore, one should follow the available information in order to understand the difference between these animals. However, there are not many information sources with both these animals being discussed together, but this article does have summarized information about rhesus monkey and uakari with a comparison at the end. Therefore, it would be interesting and useful to follow the presented information here.
Rhesus monkey, Macaca mulatta, is also known as the rhesus macaque. Rhesus monkey, being a macaque, is an old world monkey and one of the best-known species too. There are seven or more subspecies of rhesus monkey, varying according to the geographical localities, and they are native to South, Central, and Southeast Asia. Grasslands, woodlands, mountain regions, and sometimes around human habitations have been their inhabited areas. These intelligent primates have also conquered the mountainous areas with altitudes over 2,500 metres. The adult males are about half a metre in length and almost eight kilograms in weight. The females are usually smaller than the males. The dentition is exactly the same as in humans, but the canines are considerably large. They are excellent in many locomotive aspects including walking on ground, climbing trees, moving or jumping among trees, and swimming. However, they do not readily live in water, but the arboreal and terrestrial lives are highly preferred by them. Rhesus monkey has a brown or grey colour coat with a dull pink coloured face. Their whole body is covered with dense fur except the face, ears, and the palms. Rhesus monkey usually herbivorous in food habits, but occasionally they feed on animal matter, as well. They are active during the daytime and live in large groups called troops, where the sex ratio of female to male is usually 4:1. Their communication is complex as in humans with facial expressions, vocals, body postures, gestures, and many more.
Uakari is any of the four species of the genus: Cacajao. Uakaris are new world monkeys and unique among the primates with their characteristically bald and pink head. They range in the South American continent, especially around the Amazon forest. Their whole body is covered with loose and long hairs except for the head, face, palms, and ears. Their forehead appears more prominent with the baldness of the head. Their body lengths vary from 35 to 55 centimetres and weigh about 2 – 3 kilograms. Despite their arboreal lifestyle, the tail is small compared to the rest of the body. Uakaris are herbivorous in feeding habits and live on trees more often than not. They have been lethargic animals in captivity but very active in wild. There are records of leaps exceeding six metres. Uakaris live in troops with a large number of individuals sometimes up to 100. According to the IUCN, uakaris are listed as endangered species.
