Who own these eyes?

Have you ever noticed the different shapes of pupils among animals? Here, I suggest you guess to which species they belong. (move your mouse over the pictures to know the answers)

 

But why so much diversity?

Explanation

The pupil is the opening conducting light toward the retina and each animal has different needs regarding eyesight.

Generally speaking, preys “prefer” a large field of view to detect potential predators. On the other hand, predators have a smaller field of view for better hunting accuracy.

Thanks to each shape of pupils, photoreceptors are optimally reached for survival of the animal.
