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.
Antilopinae
The Antilopinae are a subfamily of Bovidae. The gazelles, blackbucks, springboks, gerenuks, dibatags, and Central Asian gazelles are often referred to as "true antelopes", and are usually classified as the only representatives of the Antilopinae. True antelopes occur in much of Africa and Asia, with the highest concentration of species occurring in East Africa in Sudan, Eritrea, Ethiopia, Somalia, Kenya, and Tanzania. The saigas and Tibetan antelopes are related to true antelopes (Antilopinae) and goats (Caprinae), but often placed in their own subfamily, Saiginae. These animals inhabit much of central and western Asia. The dwarf antelopes are sometimes placed in a separate subfamily, Neotraginae, and live entirely in sub-Saharan Africa.
