Ever Wondered Why The Pupils Of Some Animals Are Either Horizontal Or Vertical? Animals They say animals have an incredible sight. They can see things which we cannot even imagine of seeing with our naked eyes. And, it's true that they have a knack of seeing spirits floating in the air. (hint: if you ever find your pet howling for no reason, just keep in mind that he is seeing an unusual object floating in the sky. And, no, your pet isn't sick!) If you ever noticed the pupils of animals, some are horizontal, and vertical while others are circular. There's a reason behind it. Let's read on to know what are they.
Here we go...
Researchers at the University of California, Berkeley and Durham University in England...
...conducted a study regarding this.
Vertically-shaped pupils.
The studies revealed that the animals which are predators (tigers, lions being the exception) and are active
during the night have vertically shaped pupils.
Moreover, there lies a law of physics behind the shape of the eyes.
Vertical eyes help the predators to ambush themselves in the ground and to gauge how far away the prey is.
Horizontally-shaped eyes.
On the other hand, all the herbivorous animals have horizontally-shaped pupils. These animals bent their heads downward to graze, their eyes rotated to keep the pupils parallel to the ground.
Round pupils.
Did you know the below fact?
Since these animals attack above the ground, they don't need vertical pupils. "This work is another piece of the jigsaw puzzle of understanding how eyes work.” -- Gordon Love, a professor of physics at Durham University and co-author of the study Recommended for you: Ever Wondered Why An Itchy Tip Of Your Nose Is Bad?
