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.
Giant anteater
This animal is an insectivore, feeding mostly on ants or termites. In areas that experience seasonal flooding, like the grassy plains of the Venezuelan llanos, anteaters mainly feed on ants, because termites are less available. Conversely, anteaters at Emas National Park eat mainly termites, which occur in high density on the grasslands. At Serra da Canastra, anteaters switch between eating mainly ants during the wet season (October to March) and termites during the dry season (May to September).
