More than 800 languages are spoken in Papua New Guinea.

It's hard to imagine anyone being able to speak—or even understand—all of the 850-plus indigenous languages that are spoken in Papua New Guinea. And in reality, most people don't. Many of the languages in the country—such as Nihali—are only spoken and understood by a few thousand people in the world. Still, the sheer number of languages that exist in Papua New Guinea make it one of the most linguistically diverse countries in the world.

There are snakes with two heads, which compete with each other for food.

The fact that some snakes are born with two heads is pretty incredible as is, but what about the added detail that these heads are actually two distinct parts that both work with one another and also see each other as competition?
