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.

Like other neotragines, the royal antelope is monogamous, though polygamy has been occasionally observed. Individuals of both sexes have been known to reach sexual maturity by six months of age. Births have been reported in November and December. Typically a single, delicate offspring is born after an unknown gestational period, weighing – nearly a third of an adult's weight. Young appear similar to adults in colouration. The maximum lifespan of a captive royal antelope was estimated at six years and eight months by a 1993 study.
