The Monkey with a Bright Blue Bottom

Mandrills live in large "supergroups" or "hordes" that can contain hundreds of individuals. [40] [50] [51] These large groups are fairly stable and do not appear to be gatherings of smaller ones. At Lopé National Park, Gabon, mandrill hordes were found to have an average of 620 individuals, and some groups were as large as 845, making them possibly the largest cohesive groups of wild primates. [51] Another study in Lopé found that a horde of 625 mandrills consisted of 21 dominant males, 71 less dominant and subadult males, 247 adult and adolescent females, 200 juveniles, and 86 dependent infants. [40] A mandrill horde of around 700 individuals in northern Lopé had a total home range of 182km 2 (70sqmi), 89km 2 (34sqmi) of which was suitable habitat. The supergroup would occasionally diverge into two to four subgroups before reuniting. [52] Another 15-month long study of a 120 member group found a home range of 8.6km 2 (3.3sqmi) with an average traveling distance of 2.42km (1.50mi) per day. [47] Mandrills grooming at Natura Artis Magistra Mandrills are noted for being among the most colorful mammals. Charles Darwin wrote in The Descent of Man: "no other member of the whole class of mammals is coloured in so extraordinary a manner as the adult male mandrill". [30] The red coloration is created by blood vessels near the surface of the skin, [31] while the blue is a form of structural coloration caused by parallel arrangements of collagen fibers. [32] The blue ridges on males contrast with both the red facial hues and the green foliage of their environment, helping them stand out to other individuals. [33] The darker and more subdued coloring of female faces is caused by melanin. [34] Ecology [ edit ] Female mandrill sitting in tree Charpentier, M. J. E.; Mboumba, S.; Ditsoga, C.; Drea, C. M.

Monkeys, like many primates, use sexual swellings to indicate fertility. The increased hormonal activity around the genitals during ovulation causes the skin to turn pink, a phenomenon known as tumescence. The Science Behind The Monkey Butt Vibrant Coloration? The Rhesus Macaque, also known as the red bottom monkey, is a species of Old World monkey native to Asia. These monkeys have distinctive reddish-brown fur and long tails, are social and live in groups of up to 30 individuals. Females reach sexual maturity at around three years, while males reach maturity at approximately four years. Rhesus macaques typically mate during the summer months. After a gestation period of 155 days, the female will give birth to a single infant. Females are characterized by their very red bottoms, which are essential to mate choice. Studies also show that females with redder bottoms are more likely to acquire a mate.

Pourquoi stories” are ones which give explanations for the origins of animals, and also some of their characteristics. They are present in many different cultures, and are often now told to entertain. This one fits the bill perfectly. Just why is it that some monkeys have startlingly coloured faces - and rear ends? This book offers an explanation why. At least three other anthropoid primates are exclusive to the region, according to the researchers—the Lomami River red colobus, the Lomami River blue monkey, and the Kasuku River Wolf’s monkey. Like all of Congo’s remaining large mammals, these species are threatened by uncontrolled commercial bush meat hunting and habitat loss. a b c d e f g Hoshino, J. (1985).

Cytochrome-b sequences suggest that mandrill populations north and south of the Ogooué River split 800,000 years ago and belong to distinct haplogroups. This divergence appears to have also led to the splitting of the mandrill strain of the simian immunodeficiency virus (SIV). [17] The draft (incomplete) genome of the mandrill was published in 2020, with a reported genome size of 2.90 giga–base-pairs and high levels of heterozygosity.

Lesula is an Old World monkey species living in the Congo‘s Lomami Basin. This monkey has startlingly characteristic human-like eyes and a blue bottom. Though the international scientific community was unaware of its existence until 2007, the local population was aware of its presence for some time.

Some authorities have divided mandrill populations into subspecies: the northern mandrill ( M. s. sphinx) and the southern mandrill ( M. s. madarogaster). A proposed third subspecies, M. s. insularis, was based on the mistaken belief that mandrills are present on Bioko Island. [14] [15] The consensus is that mandrills belong to one subspecies ( M. s. sphinx). [16] The different colors of the primate’s butt come from the arrangement of the tissue in the area, reflecting specific light wavelengths. Therefore, mandrills have blue butts, while other monkeys have pink, red, or bright blue bottoms because of tumescence, which occurs due to the hormones produced during ovulation. They are classified as monkeys because they have tails. Apes, on the other hand, do not have tails. What Monkey has a Colorful Bottom?
