20 omnivorous animals

Human beings are animals and, more specifically, they belong to the omnivores; a classification obtained through reviews on evaluation, teeth, diet and other details. However, humans are not the only ones on the list and they are accompanied by a wide variety of animals that could surprise some.


What is omnivore?

If you want to know what omnivores eat, the answer may be simple at first. When a living thing is omnivorous, it means that it can eat a diet that includes foods commonly eaten by herbivorous and carnivorous animals at the same time.

In simple words, any being that has the ability to feed on plants and meat at the same time, belongs to this category. This is important, since knowing what animals eat is crucial to classifying them and placing them in the food chain, an order that is fundamental in nature.

On the other hand, there are species that have been so domesticated that their very diet has been influenced by human intervention and has turned them into omnivores; such is the case of chickens and pigs. For these species, humans have shown great talent in designing all kinds of feeders, using various materials at their disposal and tools, which can range from a simple hammer to a professional planer. All with the intention that these domestic animals feed comfortably.
