All Colobinae have complex stomachs adapted to fermenting a vegetarian diet. Contributor Galleries To aid in digestion, particularly of hard-to-digest leaves, they have multichambered, complex stomachs, making them the only primates with foregut fermentation. (Nowak, 1999). ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe.

Because of their dietary requirements, they spend the better part of the day foraging. The King colobuses are herbivores (folivores), their diet generally consists of soft, young leaves, growing on treetops. As mentioned above, a colobus monkeys diet mostly consists of leaves. The three genera of colobus monkeys are classified in the subfamily Colobinae, which also includes leaf monkeys such as langurs. Colobus monkeys are capable of eating toxic foliage. These monkeys rarely descend to the ground. animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Plant & Animal Adaptations in Swamps | Sciencing They are closely related to the red colobus monkeys of genus Piliocolobus. In many regions they are extremely abundant, but, where their forest habitat has been altered by logging or fire, they are much less resilient than black-and-white colobus. Polygyny:A pattern of mating in which a male animal has more than one female mate. King colobus monkeys eat leaves during and following the monsoons, but as drought takes hold of the forest the monkeys turn to fruits and other plant foods to survive. Shade-tolerant shrubs, small trees, woody vines, and herbs comprise the vegetation of this layer. Each group lives in a territory in the trees, which the males mark by a jumping-roaring display consisting of a loud rattling call accompanied by a vigorous display of leaping about and dropping from tree crown to lower branches. Currently, this species is classified as Vulnerable (VU) on the IUCN Red List. The family Cercopithecidae includes 22 genera and 133 species. It lives in small teams consisting of three to four females and 1 to three males, plus theyre younger. Reproductive details are not known for this monkeys except that the mother carries her baby in her mouth for the first few weeks after birth a habit shared only with other species of colobus. Its skin has been used to make dance costumes, hats, and capes. West Africa has two monsoons each year. Black-and-white colobus are about 5560 cm (2224 inches) long, with a tail that is significantly longer than the body. Once the young reach seven months, they begin playing with juveniles. Further, the tail is entirely white and not tufted (Nowak, 1999). A troops home range is about 54 acres (22 hectares) on average, with home ranges of different groups overlapping significantly. It can be found foraging on the ground and typically stays within a foraging path of approximately 500 meters. Bamboo stands are also popular dwelling spots for this species.

The two species of black and white colobus monkeys are found in Kenya, those that inhabit coastal forests and those in inland high-country areas. At one time this species was hunted excessively for its beautiful fur. Colobus groups typically have a daily foraging path of only about 500 meters. The king colobus is listed under Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which controls trade of the species to prevent it from becoming endangered, and Class A under the African Convention on the Conservation of Nature and Natural Resources, the highest level of protection under this treaty, which completely bans the hunting and collection of this species except under very specific circumstances. Each troop has its own territory, with feeding areas and sleeping trees, but may sometimes join with other troops to form a group of 50 or so. Males compete by calling; the dominant male has the loudest call. Infants are carried on their mothers abdomen, where they cling to her fur. [8][9] There appears to be a dominant male, whilst there is no clear dominance among female members. Some groups will temporarily have multiple males, but they leave once they have matured. cross-species transmissions were thus possible, but the viral adaptation was insufficient to allow a spread of the virus .

Though it is arboreal, it eats primarily on the ground. The thumb is reduced to a mere tubercle, the skull is somewhat prognathous, and the orbits are oval with narrow superciliary ridges (Nowak, 1999). They write new content and verify and edit content received from contributors. rainforests, both temperate and tropical, are dominated by trees often forming a closed canopy with little light reaching the ground. These monkeys are widely distributed in the Old World from southern Europe (Gibraltar) into NW Africa; throughout Africa south of the Sahara; and through central and SE Asia, including southern China and most of Japan. The ability to consume foods that others cannot is an evolutionary adaptation that gives them a distinct advantage over other species. The Animal Diversity Web is an educational resource written largely by and for college students. [2] Maintaining this species in captivity has mostly failed and focus has been on managing the habitats to prevent further degradation and habitat destruction that could harm the species. In some groups, C. polykomos has been observed to give birth year round, but in others the birth season coincides with the dry season (December-May). Juveniles are treated as a lower-rank (in regards to authority) than subadults and likewise when comparing subadults to adults.

Theyhave a strong preference for primary forest, and only rarely inhabit secondary forests or habitats that are degraded. [1] They are generally found in high-density forests where they forage on leaves, flowers and fruit. During the infrequent encounters between groups, adult males engage in aggressive displays with one another. King Colobus has been proven to reside roughly 23.5 years in captivity and probably round 30 years within the wild. Even replanting a forest that was clear-cut wont be enough for the species to thrive, since the monkeys rely on primary forest that has developed its unique ecological features over hundreds of years.

Current rates of deforestation of the African rainforests are relatively low compared to the rest of the worldbetween 2000 and 2010, an average of 0.72 million acres (0.29 million hectares) of forest were lost per year, a decrease by about half from the previous decade. The motivation behind this intergroup aggression differs between males and females. Distribution: Coastal region of West Africa, with a small, isolated population living in eastern Nigeria. Members of the . Generally, however, it is thought that the main purpose of calling is to maintain spatial distance between two groups or between male members within one group.
