Royal antelope
A herbivore, the royal antelope prefers small quantities of fresh foliage and shoots; fruits and fungi may be taken occasionally. Though the antelope is considered to be nocturnal, zoologist Jonathan Kingdon holds that feeding occurs throughout the day, though some foraging may also be observed at night. In comparison to Bates's pygmy antelope, the royal antelope has a longer muzzle, broader lips, a smaller mouth and smaller cheek muscles. These features do not allow complete digestion of lignified growth. Individuals may often move into new locations foraging for fresh growth.
