There are certain abilities that humans possess which we often take for granted, simply because we’ve always had them and never known anything different.
However, when compared to animals, you might be surprised to discover that even our ability to look up is quite special. Did you know that pigs can’t look up at the sky? Due to the anatomical structure of their necks and spines, this is one task that these animals can’t do.
To begin with, pigs have eyes on the sides of their heads. This is common in animals that have to always be on the lookout for predators. But while this gives them a panoramic view of 310 degrees, this positioning also means that they have a blind spot directly in front of their snouts and another directly above their heads, which makes it impossible for them to look up, as they only have a 50-degree upward vision.
