Herbivore Definition: Herbivores are animals that only eat plant-based materials, such as leaves, fruits, stems, seeds, nectar, roots, bark, etc.
The term “herbivore” refers to animals that chew leaves, and insects that harm a plant by sucking sap, as well as more benign species that only gather pollen, nectar, or plant resin.
Both terms have Greek roots: “phyton,” which means “plant,” and “phagein,” which means “to eat or devour.”
There are thousands of herbivorous animals in the ecosystem.

Bison | Grasses, weeds, and leafy plants. |
Buffalo | Grasses, rice straw, weeds, and leafy plants. |
Camel | Grass, grains, and wheat. |
Cow | Grasses, rice straw, weeds, and leafy plants. |
Deer | Leaves, twigs, shoots of plants, vines, and rarely grass. |
Donkey | Barley straw, hay, and grass. |
Iguanas | Leaves from trees and vines. |
Bees | Pollen and nectar. |
Earthworms | Decaying roots and leaves. |
Rhinoceroses | Grass, twigs, leaves, and small branches. |
Rabbits | Hay, grass, fresh vegetables, few pellets |
Goat | Weeds, grasses, hay, grains, and small tree barks. |
Oxe | Grasses, rice straw, weeds, and leafy plants. |
Few Birds (sugarbirds, Cassowaries, Canada Geese, etc) | Fruits, seeds, etc. |
Herbivorous Fish (Acanthurus Lineatus, Acanthurus Nigrofuscus, Parrotfish, and Unicornfishes). | Algae and leaves of small plants. |
However, the herbivores have been separated into several groups based on their feeding strategies.

Facts and Characteristics of Herbivorous Animals
- Entomologists frequently refer to any of these dietary strategies using the noun “phytophagy” and the adjective “phytophagous.”
- Herbivores are animals that consume plant tissues or plant-based products.
- Herbivory has had both positive and negative impacts on plants over evolutionary time.
- The ability of flowering plants (the Angiosperms) to draw in insect herbivores and use them as pollinators have undoubtedly been advantageous.
- However, some insects can also act as carriers of plant diseases.
- Animals have had to adjust to many of the traits that plants have in order to use them as a food source.
- To defend themselves against toxic substances found in plants, herbivores must have developed detoxification pathways.
- Animal herbivores have the ability to, directly and indirectly, change the composition of plant communities.
- Some herbivores strengthen the defenses of plants.
- Certain plants can exhibit symbiotic interactions with ants that shield their host plants from other herbivores and also regulate the growth of nearby plants through weeding and pruning.
- Plants have a variety of external structures, including leaves, stems, flower components, roots, fruits, and seeds.
- Various plant species may have different versions of each of these structures. Therefore, herbivores should have some traits that enable them to exploit these structures.
- These include hard limbs for digging, saw-like, piercing, or cutting organs (like the chewing mouthparts of insects), and appendages (like claws, spines, or suckers) that allow them to cling to vertical or upside-down surfaces. They should also have wings to reach the tops of the tallest plants.
- The majority and widest variety of herbivores are insects. According to estimates, herbivores make up about half of all living insects.
- To eat hard plant material, herbivorous animals use a variety of strategies.
- These include forming partnerships with other organisms and avoiding hard plant material by consuming plant fluids.
- Other strategies include using chewing mouthparts to gnaw on tough parts and eating soft internal tissue.
