Herbivorous organisms are those that feed on plants. According to the Merriam-Webster Online Dictionary, the word herbivorous comes from the Latin word herba, meaning grass, and vorus, meaning "feeding on."

Animals that are herbivorous are known as herbivores. An example of an herbivorous marine mammal is the manatee, which eats sea grasses and other aquatic plants.
