Elephants are an example of a mammalian folivore. In zoology, a folivore is a herbivore that specializes in eating leaves. Mature leaves contain a high proportion of hard-to-digest cellulose, less energy than other types of foods, and often toxic compounds. [1] For this reason, folivorous animals tend to have long digestive tracts and slow ...

Victivores (Latin: victus=living) gather live plant material and thus include frugivores, nectivores, graminivores, granivores and folivores as subcategories. Lectivores, such as many termites, gather dead plant material (Latin: lectus=bed which is the root of the word litter, as in leaf-litter) and thanatophages (Greek: thanatos=death), such ...
Herbivore is the anglicized form of a modern Latin coinage, herbivora, cited in Charles Lyell's 1830 Principles of Geology. [3] Richard Owen employed the anglicized term in an 1854 work on fossil teeth and skeletons. [3]
Herbivores are dependent on plants for food, and have coevolved mechanisms to obtain this food despite the evolution of a diverse arsenal of plant defenses against herbivory. Herbivore adaptations to plant defense have been likened to "offensive traits" and consist of those traits that allow for increased feeding and use of a host. [1]
Social sciences including anthropology, ethnography, and archaeology have long investigated human interactions with living things. Anthropology and ethnography have traditionally studied these interactions in two opposed ways: as physical resources that humans used; [3] and as symbols or concepts through totemism and animism.

More recently, dietary habits have been influenced by the concerns that some people have about possible impacts on health or the environment from genetically modified food. [172] Further concerns about the impact of industrial farming on animal welfare, human health, and the environment are also affecting contemporary human dietary habits.
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
