Eyes evolved based on the animal's needs. How Fascinating. https://www.facebook.com/letslearnsomethingbygenmice/posts/pfbid0HZE57BmrUUV7kBNerrVhusbJsYmZkRTockHYBgJKviqX5qGU4bsxzKPxEqQSZezsl?mibextid=xfxF2i

Animals with horizontal pupils, like sheep, goats, deer, and horses, are usually prey species. These horizontal slits give them a panoramic view of the horizon, allowing them to see threats coming from nearly all directions without moving their heads much.

This wide field of vision is crucial because it helps them quickly spot predators approaching on land or low to the ground. The horizontal pupil also stabilizes their vision as they move across uneven terrain, helping them maintain balance and awareness.

On the other hand, animals with vertical pupils, such as cats, foxes, snakes, and crocodiles, tend to be predators. Vertical slits enable these animals to control the amount of light entering their eyes with great precision, especially in low-light or nighttime conditions.

This improves their ability to judge distances accurately, which is vital for stalking and ambushing prey. Vertical pupils also enhance depth perception and allow for sharp focus on objects directly in front of them.

In summary, pupil shape is a fascinating example of how evolution shapes anatomy to match an animal’s lifestyle, horizontal pupils for vigilant prey and vertical pupils for stealthy hunters.
