The predatory mammals (which includes us humans) -- flesh-eating hunters such as the cats the dogs, wolves and foxes; the bears; and the weasel family -- have binocular vision: eyes in the front of their heads, with powerful eye muscles that enable them to focus very rapidly and to contract or dilate the pupils according to whether the light is bright or dim. An animal that is preyed upon by many enemies has its eyes out on the sides of its head: each eye with its own field of vision. For example, a cottontail rabbit can see what is above, behind, on either side, and in front of it except what is right before its nose. He probably does not see the clover leaf he eats. Species which are hunted by other animals but which are predators themselves at times, commonly have eyes that are a compromise. A possum's eyes are located at an angle of about 30 degrees with the axis of the body.
