> Which animals have eyes with rectangular pupils?And the answer: goats. An animal's pupils can give a hint as to whether they're prey or a predator.Predatory animals tend to have vertical slit pupils, while herbivores that areprey for other animals, like goats, usually have horizontal pupils.While your average indoor cat likely isn't engaging her sharp eyes to catch miceor other prey, it is that predator/prey distinction that accounts fordifferently shaped eyes. Horizontal pupils have evolved to enable a nearlypanoramic view, allowing the herbivores to scan for danger from a greatdistance. While larger prey animals such as horses and sheep are constantlypitching their heads downward to graze, their pupils remain parallel to theearth. By swiveling their eyes outward these peaceful creatures are able to keeptheir surroundings in view while enjoying their meal.Meanwhile, predators with vertical pupils, such as cats and crocodiles, usetheir thin line of vision to narrow in on prey across visual obstacles, oftenthrough some sort of concealing foliage. The thin-slitted eyes of these shorterpredators is ideal for judging distance and enables them to pounce with greataccuracy. However, larger predators such as lions and tigers (and bears, oh my!)each have more human-like round pupils. This is due to the evolutionary huntinghabits of bigger predators: animals higher off the ground require more holisticvision to chase after their prey.
