Bates's pygmy antelope
Bates's pygmy antelope eat leaves, buds, shoots, fungus, grass, and herbs. They also eat crops, which makes them unpopular with farmers. They are often caught in snares near agricultural fields. They have a typical territory of . Males are territorial, marking their territory with scent produced in the preorbital glands.

One young is born per pregnancy. The fawn weighs between .

Food supplies, such as algae the tadpoles eat, also affect the sexual maturity of the species. Reportedly, the "amount of protein in different algae, can affect size at and time to metamorphosis" and "these food effects may be mediated through diet-induced changes in thyroid function", which means the food the tadpoles ingest dictates the changes in the thyroid gland's production of certain proteins. Tadpoles most commonly feed on algae, diatoms, and detritus. As the species grows older, it changes its diet to animal tissue which must be swallowed whole because the frog's jaw is structured on a hinge joint that does not allow for sideways movement as in humans. Adult frogs eat a range of foods such as moths, ants, grasshoppers, hornets, beetles, flies, water striders, and snails.
