Stephen Miller, age 11, of Indianapolis, Indiana, for his question:

Do worms have eyes?

Even if Andy never went outdoors, he would know when the fishing season is at hand. The mail brings all sorts of questions about worms. Just so all you young fisherman don't worry about the worm’s feelings the hook will not cause him pain as we know it. The nervous system of the worm is such that he does not feel pain as we do.

As to eyes, the little pink fellow has none. Yet he can toll the difference between light and darkness. He may be creeping forth from his burrow in the pale dawn when you turn a flashlight on him. He senses this sudden flood of light and goes back indoors.

The worm's skin has special cells which are sensitive to light. These cells operate over most of his body. Instead of one pair of eyes he has countless small cells to inform him of the difference between light and darkness. But, of course, they do not give him a detailed picture of the scenery.
