8 creatures that don't have round pupils

Cats: Cats have vertical slit pupils that constrict to thin lines in bright light and widen into large ovals in low light.

Goats: Goats have horizontal rectangular pupils. This shape gives them a wider field of view, allowing them to see predators approaching from the sides.

Sheep: Similar to goats, sheep also have horizontal rectangular pupils for enhanced peripheral vision and depth perception.

Octopuses: Octopuses have W-shaped pupils. This unique shape is thought to help them perceive polarized light.

Cuttlefish: Like their octopus cousins, cuttlefish also have W-shaped pupils that aid in their vision and light sensitivity.

Snakes: Most snakes have elliptical pupils that are vertically oriented. This allows them to focus on prey and strike accurately.

Crocodiles: Crocodiles have vertical slit pupils similar to cats. These pupils help them to see well in water, both during the day and at night.

Horses: Horses have horizontal rectangular pupils, much like goats and sheep. This wide field of view helps them to see predators approaching from any direction while grazing.
