Duiker are small antelopes that inhabit forest or dense bushland. They are a good example of how an animal can be very successful in finding and filling a certain ecological niche. They are the most widespread of all the forest antelopes and are represented in East Africa by 13 of their 17 species. A striking peculiarity of duiker in the genus Cephalophus is that they all have the same distinctive body type, although the different species vary in size. Duikers have low-slung bodies on slender legs, wedge-shaped heads topped by a crest of long hair, and relatively large eyes. With their heads held close to the ground, duikers can move easily through the dense vegetation of forests and bushlands. They regularly run through these areas and when disturbed, plunge into thick cover to hide. This trait is the source of the name "duiker," which in Dutch means "diver."
