Wikipedia Meaning and Definition on 'Omnivorous'
Omnivores (from Latin: omni all, everything; vorare to devour) are species that eat both plants and animals as their primary food source. They are opportunistic, general feeders not specifically adapted to eat and digest either meat or plant material primarily.
Omnivory has evolved several times among different groups of animals. The first vertebrates were piscivores, then insectivores, carnivores and finally herbivores.
Although the term omnivore literally means eater of everything, omnivores cannot really eat "everything" that other animals eat; they can only eat things that are at least moderately easy to get and still at least moderately nutritious. For example, most of them cannot live by grazing (easy to get, but not nutritious enough), nor can they eat some hard-shelled animals or successfully hunt large or fast prey (nutritious, but too hard to get).[See more about Omnivorous at Dictionary 3.0 Encyclopedia]
