-Researchers used computer models based on a sheep’s eye to support theories about why horizontal, vertical and circular pupil shapes benefit different animals.
Why do the eyes of some animals, including goats, have horizontal-shaped pupils, while others, such as rattlesnakes and domestic cats, have vertical slits?
It is a question that has longed intrigued researchers, and a study of 214 species published Friday suggests the answer may be strongly linked to giving animals a survival edge: Vertical pupils and circular pupils help certain predators hunt, while horizontal pupils help other species spot predators from afar.
