Consider why your two eyes are located on the front of your face. Think of other animals with this same arrangement. Some examples are lions, wolves, and owls. What do these creatures have in common? They are all animals that hunt. These animals have eyes facing directly in front of them. This provides a field of vision that is about 180 degrees wide, like a half-circle. This kind of sight is called binocular vision. On the other hand, animals that are hunted have eyes on the sides of the head. This provides nearly a 360-degree field of vision. Because these animals need to be on the alert in order to stay alive, they need to see things coming from the sides and from behind. However, without stereoscopic vision, these animals have a more difficult time determining how far away a threat is.

Compare and contrast animals with binocular vision to those with stereoscopic vision. Which statement is true?
