One of the most unnerving things about a snake is its steady gaze. If you have ever had those unblinking eyes fixed on you, even through a zoo window, you will know what I mean.
For a snake, its penetrating stare is a terrific way of scaring prey. Some animals are turned rigid with fright when they see a snake’s eyes, glaring at them. But the reason they cannot blink is not quite as calculating. Snakes cannot blink because they do not have eyelids. They cannot even close them to go to sleep. Instead they have a permanent glassy stare that can turn most creatures cold with fear.
