A colobus monkey's diet consists of 80% leaves and about 15% fruit. Why only 15% fruit? Because in the forest, where these colobus monkeys live, fruit is seasonal. So when fruit is not in season, these monkeys eat a lot of leaves to meet their dietary needs.
What is black and white, weighs about thirty pounds, and lives in trees? No, it is not a giant, arboreal skunk—it’s a colobus monkey! One of the most distinctive of all primates, the colobus’ dramatic coloration is a beautiful sight against the deep green background of central Africa’s rain forests. They have long, thick hair, with a cape-like trim of white for a dramatic appearance. Finishing the look is a two-foot-plus long tail, ending in a fluffy tip of white.
