Girls who stare at goats

Have you ever made eye contact with a goat? I did on Sunday. And let me tell you, their eyes are creepy.

Instead of round pupils like most everything else that has eyes on the planet, goats' pupils are rectangular. I wonder if they see everything in widescreen format?

After searching a short time, but still longer than I thought, the best answer I found was that the rectangular pupils allow them to look all around without have to move their eyes. This also helps them see better at night.

And, here's an extra bit of trivia, octopuses have rectangular pupils too.

I bet you never knew you wanted to know that.
