Animals which have eyes placed upon the sides of their heads (e.g. squirrels, zebras, frogs etc.) are typically herbivores and prey for carnivores. Herbivores need to have their field of vision constantly focused upon what’s going on around them. Animals which have eyes on the front of their heads (e.g. owls, tigers, human beings etc.) are usually carnivores. Carnivores are predators and because of this they need to constantly be focused upon what is in front of them for activities like chasing down prey in an attempt to capture and eventually kill what they catch. Human beings can demonstrate this difference for themselves by placing one’s hands in front of their eyes as they would binoculars, then crossing their wrists and cupping their hands so that they see only from the sides of their face. This demonstrates the different abilities predator and prey have in respect to what is in focus within a particular classifications field of vision. Panoramic vantage points which herbivore prey have allow for more information to be taken in at once, but binocular vantage points which carnivorous predators have allow for depth perception which most herbivores do not have, and even when they do have it, it’s accuracy is highly limited
