Omnivore

Definition

noun, plural: omnivores

An animal that includes both plants and animals in its normal diet


Supplement

Animals may be classified based on the type of their normal diet. Animals that feed (exclusively) on animals are called carnivores. Those that feed (exclusively) on plants are called herbivores. Animals that feed both on animals and plants are referred to as omnivores.

Omnivores are a group of animals that derive energy and nutrients from a variety of food sources, such as plants and animals, as well as fungi, algae and bacteria.1 Because of the wide variety of food sources, omnivores are also called all-eaters. However, compared with other animal groups such as carnivores and herbivores, the omnivores lack distinctive specializations in acquiring and processing food.2

Examples of omnivores are chimpanzees, orangutans, gorillas, pigs, most bears, hedgehogs, opossums, skunks, sloths, squirrels, mice, rats, rodents, raccoons, and many others. Humans are regarded as omnivores. However, there are those who are selective in their diet and chose to feed solely on plant materials (i.e. vegans).


Word origin: Latin omnis (all) + Latin vorare (to devour)

Need help figuring out this skull

... quite big :lol: Anyway, back to the problem. It looks, it doesn't have big incisors or canines, so I would guess it's skull of some herbivore or omnivore or something like that ;) But it looks quite small, right? Nevertheless, as you don't have much from the skull, the only way to determine it ...

NEED SKULL IDENTIFED

... carnivores like cats. The eyes are oddly on the top of the head, not facing front like most carnivores have. So I'd go for a herbivore, or an omnivore maybe. Although the incisors (and the size of the skull) seem to count rodents out as well. But these are just guesses at this point. I'll ...

Artificial Life Created

... not only growing the plants, but synthesizing the fertilizer and pesticides? There's so many issues with corn agribusiness, it's insane. Read The Omnivore's Dillemma by Michael Pollan if you haven't already. Good book.
