Mountain gorillas occasionally eat invertebrates, but they are primarily folivorous. They eat the roots, leaves, stems, and pith of herbs, vines, shrubs, and bamboo. Their diet is supplemented by small amounts of bark, wood, roots, flowers, fruit, fungi, epithelium stripped from roots, galls, invertebrates, and gorilla dung.
