4. Goats

The square pupils of goats attract a lot of attention, but they aren’t just there to look pretty. The width of the pupils allows the animals to see at a 330 degree angle, as opposed to humans who generally see at around a 185 degree angle.

Frogs are well-known for their big eyes, but few people know why their eyes bulge out. They can protrude their eyes to help them see above the surface while they are underwater.
