The eye of the snail
One of my macro photos shot today.
In fact, snails are almost blind.
Snail's cup shaped eyes can only tell the difference between light and dark and also they can see where the light comes from.
But they cannot distinguish forms and they can certainly not see any pictures.

Amazing that you could focus on just the eye like this! If the snail could see, it would love the photo!
