Mandrill
The mandrill is an omnivore. It usually consumes plants, of which it eats over a hundred species. It prefers to eat fruits, but will also eat leaves, lianas, bark, stems, and fibers. It also consumes mushrooms and soil. Carnivorously, mandrills mostly eat invertebrates, particularly ants, beetles, termites, crickets, spiders, snails, and scorpions. It will also eat eggs, and even vertebrates such as birds, tortoises, frogs, porcupines, rats, and shrews. Mandrills likely will eat larger vertebrates when they have the opportunity, such as juvenile bay duikers and other small antelope. Large prey are likely killed with a bite to the nape with the mandrill's long canines. One study found the mandrill's diet was composed of fruit (50.7%), seeds (26.0%), leaves (8.2%), pith (6.8%), flowers (2.7%), and animal foods (4.1%), with other foods making up the remaining (1.4%).
Four-toed elephant shrew
Four-toed elephant shrews are heavily dependent on rich leaf litter composition for their food and nests. Their main prey are small invertebrates. Ants and termites are most common, as well as crickets, grasshoppers, spiders, centipedes, millipedes, and earthworms. Seeds, fruits, buds, and other plant material also form part of their diets. Four-toed elephant shrews eat much like anteaters; they flick small foods into their mouths.
