Why are the eyes of the gazelle on the side of its head?

Animals that are victims of predators usually have their eyes towards the side of their heads because this provides a large (360 degree) field of vision. This allows them to spot predators coming from any direction. Most herbivorous animals have eyes on the sides of their head, including the rhinoceros, parrots, deer, rabbits and horses.

On the other hand, acute stereo vision is required by most predators, whose eyes tend to be closer to the front of their heads such as eagles, lions and dogs.
