The Barn Owl
Barn owls, and all owls, are capable of doing strange things with their bodies. Because their orbital sockets are very shallow in their skulls, it means that their eyeballs can’t move. They can blink, but they cannot move up and down or side to side. That means that they compensate for this by moving their heads. Moreover, they can move their heads an impressive 270 degrees. That means that they can see almost everything around them just with a turn of their head. And they can even turn their heads upside down!
