Certain animals including humans have the ability to see what's in front of them to a much greater degree than species with eyes on the sides of their head. This is due to the fact that humans and other predators are hunters by evolution require the ability to see details concerning them in their frontal vision to track prey. Even birds of prey such as the eagle have eyes in the front of their head. Herbivorous animals including horses, cows and rabbits have lateral eyes on the sides of their head as hunting is not as important for the survival of the species. An exception to this rule is the hammerhead shark which was tested by scientists to have the capability of seeing in an arc of 360 degrees around its head. They therefore have greater depth perception than any other shark and the ability to see with stereo vision much like humans have the binocular disparity process that occurs. So hammerheads are not only predators but have traits of species with better lateral vision so they can see a wide variety of their environment at one time. This makes it much more advantageous for hunting as well as survival and reproducing.
