10 amazing-looking animal pupils that make it hard to tell who owns them (11 photos)

Need a bigger view? Here's a rectangular pupil! More light? Hold the pupil in a wave shape! A real treat. A human can't boast of such a thing. Everything is simpler for him, no variety. Alas, neither race nor place of residence influences this.





Catfish

Crescent-shaped pupils are not limited to catfish. This shape can also be found in stingrays and flounders. Such pupils help reduce distortion in the water and increase contrast. Such features help fish to better navigate in space, notice prey and enemies in a timely manner.

Octopus

The rectangular oblong pupils increase the octopus's field of vision to 340 degrees, allowing it to easily notice approaching danger. Goats and mongooses can also boast of a similar gift of nature.

Gecko

Some species of geckos have vertical pupils with wavy edges. They allow the reptiles to get a super-clear image, which makes them amazing night hunters.

Cuttlefish

Nature has awarded cuttlefish with W-shaped pupils. In the dark, they become almost round. However, with enough light, they take such an unusual shape, allowing rays to penetrate the pupil from different directions. Thanks to this feature, cuttlefish can see well over long distances.

Four-eyed fish

This fish sees perfectly above and below water, thanks to its amazing curved lens. Each part of the eye has its own focal length, giving the fish essentially double vision.

Frog

Frogs and toads have horizontal pupils, allowing them to better notice the vertical movements of predators. They can also become incredibly wide, which can be very useful during night feedings.

Crocodile

Vertical slit pupils let in more light, allowing for better hunting at any time, including night.

Long-snouted whip snake

This snake has the sharpest binocular vision, and all thanks to the unusual, horizontally elongated pupils, which allow it to accurately determine the distance.

Toucan

By nature, toucans have received wide pupils and excellent stereoscopic vision. Thanks to these pupils, the birds are able to see even the smallest details.
