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%).
Atakapa
The Atapakan ate shellfish and fish. The women gathered bird eggs, the American lotus ("Nelumbo lutea") for its roots and seeds, as well as other wild plants. The men hunted deer, bear, and bison, which provided meat, fat, and hides. The women cultivated varieties of maize. They processed the meats, bones and skins to prepare food for storage, as well as to make clothing, tent covers, tools, sewing materials, arrow cases, bridles and rigging for horses, and other necessary items for their survival.
