When we talk about snails, it is easy to think of their slow move. But much of the time snails don’t move at all. They are in their shells-- sleeping. In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (触角), are very weak. But its sense of smell is very strong. It helps the snail to find food and the new greens.

Scientists have always believed that snails are not able to find their way home. But Briton Ruth Brooks, a retired (退休的)teacher, has found that it is not true.

Brooks began an experiment on snails after she got mad with the snails in her garden. The snails had eaten her vegetables. She didn’t want to kill them, so she took them to another place. But she found they always seemed to come back.

Brooks did an experiment. She marked the snails in her garden with nail polish (指甲油). She placed the snails in the area around her home and made notes of their movements. She found that snails have a strong homing instinct(本能); the longest returning snail traveled back 90 meters.

Brooks has been named Britain’s best amateur (业余的)scientist after her work won the BBC Radio 4 project, So You Want To Be A Scientist. She said, “I’ve always wanted to know whether the snails that eat my plants just come back when I move them, and if they do, what is their homing distance? “I would say on the evidence (证据) that it would be safe to take your snails away beyond 100 meters or even further. If you put them somewhere nice with some food, you can be almost certain that they won’t come back.”
