Further, the tail is entirely white and not tufted (Nowak, 1999). Juveniles are treated as a lower-rank (in regards to authority) than subadults and likewise when comparing subadults to adults. This size difference is the species only sexually dimorphic trait. having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Successfullydefending his resources and territories may attract new females to a males group. (Nowak, 1999). The monkeys sleep and take refuge in the middle layers of the forest, but feed on the lowest branches. Conservation and Survival Adaptations of Temminck's Red Colobus As a potential prey species, the abundance of these monkeys may affect the abundance of predators. [4], The word 'Colobus' comes from the Greek word for 'mutilated', as all Colobus monkeys only have a short stump where the thumb would be. The thumb is reduced to a mere tubercle, the skull is somewhat prognathous, and the orbits are oval with narrow superciliary ridges (Nowak, 1999). Colobus polykomos typically live in small social groups comprised of 3 to 4 adult females and 1 to 3 adult males. [4], The king colobus has a moderate-sized range; it used to be a common and widespread species but numbers have declined over the last few decades. The females, however, remain with their birth group for their entire life. Bamboo stands are also popular dwelling spots for this species. King colobus monkeys are diurnal (active during the day) and spend the majority of their time in trees. It lives in West Africa, where it is not especially rare but is very quiet and secretive and therefore seldom seen. Wetland plants also need to remain stable in the soil if they deal with fast moving water that ebbs and flows. Synapomorphy of the Bilateria. Tougher leaves correlate negatively with ingestion rate (g/min) as they are costly in terms of mastication, but positively with investment (chews/g). So, their stomach has evolved to do just that. Habitat: Understory and middle branches of rainforest generally near to water. It may be discovered foraging on the bottom and sometimes stays inside a foraging path of roughly 500 meters.It lives in small teams of lower than four females and 1 to three males. c. are more sexually dimorphic than prosimians. The other colobus species are declining in population and are variously listed as vulnerable or rare. Each troop has a well-defined territory, which is defended from other groups. When moving between trees, these monkeys catapult themselves by branches, which serve as trampolines. polykomos for its fur. 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). Food: Leaves, fruits and flowers. ADW: Cercopithecidae: INFORMATION - Animal Diversity Web animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. 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. Groups rarely encounter other groups of the same species but when they do, males engage in aggressive displays.

Our solutions to protecting the colobus monkey: African Wildlife Foundations scientists use technology like Geographic Information System (GIS) to identify key threats to conservation and pinpoint areas that have the most potential for wildlife. Their ruminant-like digestive systems have enabled them to occupy niches that are inaccessible to other primates: they are herbivorous, eating leaves, fruit, flowers, lichen, herbaceous vegetation and bark. Occasionally, various groups of the King colobuses come into conflicts, during which males exhibit some aggressive behavior such as territorial calling, thus displaying their strength and social status.
