Rectangular pupils enhance the goats peripheral vision, allowing them to see predators in a wider spectrum than animals with oval shaped pupils. Other animals with rectangular pupils include cattle, deer, horses, and sheep.

∙ 13y agoHere's a hypothesis: Housecats evolved in the wild to chase varmints down holes. This requires a very rapid adjustment to very little light upon entering the varmint's hole. The adjustment of the eye's pupil happens more rapidly when it goes from a slit to a wide opening than if it was from a small circle to a wide circle: from a slit to a wide opening, the pupil only has to expand in one dimension, whereas from a small circle to a large circle it has to expand in two dimensions. The iris muscles that do the expanding would get more leverage if they only have to work in one dimension. Other, larger feline species such as your typical wildcat have round pupils because they are too big to go down holes after prey, and their typical prey lives out in the open anyway.
This hypothesis would also explain the role of housecat whiskers, and why they are just the width they are. They seem to be about the width of varmint holes that are wide enough for the cat to turn around in and get back out of. If a cat goes down a hole and the tunnel gets narrow enough that the sides touch the cat's whiskers, the cat can tell by that whisker touch that the hole is getting too narrow and it had better turn around now and go back out of the tunnel, lest it get trapped in a tunnel that is too narrow to turn around and get back out of.

What is the shape of a goat's pupils?
They are rectangular.
The pupils of a goat's eyes are square?
Yes, and only a few species have rectangular eyes. Sheep, Goats, Octopuses and Toads have these rectangular shaped pupils. Typically classified as prey, these animals need to have a defense both day and night. But they don't have vertical slits due to their need to survey their surroundings more accurately. The narrower the pupil in relation to the horizon, the greater the accuracy of depth perception is in the peripheral vision of the animal. The perception of depth must be considered with these animals who spend their time evading predators in a rugged terrain.
