Similar to what happens in our eyes, shark pupils dilate in the dark to allow more light to enter the eye and therefore improve night vision. While the eye of a grey reef shark (like the one in this picture) looks like a cat eye during the day, you can see in this picture that the pupil is dilated and almost round. These sharks hunt mainly at night, using a whole array of superior senses to detect and track their prey. Go compare the eyes to my last post to see the difference a few hours can make!
