Unfortunately, much of the land where monsoon forest grows is also ideal for farming, which is why much of the king cololubuss forest habitat has been cleared to make way for fields. [4] Groups seem to regularly switch up sleeping locations (suggested due to reducing risk of parasites and placement prediction) and generally do not sleep near other groups.

Occasionally, they eat charcoal, which helps to eliminate chemicals that are toxic or that slow down digestion. Olive colobus monkeys have larger feet than any of the related colobus species and also have very small thumbs. The pelts are valued by native populations as ornaments, and at one time European demand for the fur was so great that large numbers of these monkeys were slaughtered annually.

Communication in most primates is complex, involving visual signals (such as facial expressions and body postures), vocalizations, and different forms of physical contact ( such reassurance gestures, aggression, grooming). Figure 1. National Science Foundation Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. They are often under water for significant periods of time, meaning that they are frequently deprived of oxygen. This allows them to use bacterial fermentation to break down their food, which is typically low in nutritional value and eaten in large quantities. [11], As suggested by their name, adult colobi have black fur with white features. Adult troop members, especially males, make croaking roars that can be heard resonating throughout the forest.

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. Conservation status. It is unclear what the male role, if any, is in rearing offspring. There are several protected areas that maintain habitat for king colobus monkeys, including Sapo National Park in Liberia, Tai National Park in Cte dIvoire, and Tiwai Island Sanctuary in Sierra Leone. Adult males rarely interact and display a clear dominance hierarchy. In order to breakdown the leaves and get the nutrients from them, the body has to ferment them. Articles from Britannica Encyclopedias for elementary and high school students.

Some are more visible, such as the cheek pads on a male orangutan, and some are not as visible, such as cheek pouches in monkeys or a giant pandas pseudothumb. The ability to consume foods that others cannot is an evolutionary adaptation that gives them a distinct advantage over other species. [8][9] There appears to be a dominant male, whilst there is no clear dominance among female members. Life span: 28 years in captivity, probably less in the wild. And because the king colobus, and many other species, rely on primary forest, even replanting these lost trees wont replace the lost habitat.
