How Does a Snail Move?
A snail moves about by creeping on a part of its body that seems to be its stomach. It is really a broad foot. A snail’s foot is made up of many muscles.
The muscles move in a wave-like motion that slowly inches the snail forward. If you put a snail on a piece of a glass, you can easily see the rippling muscles from the underside.
As a snail crawls, it pours out a trail of slime, or mucus. The slime comes out from the front and hardens when it comes into contact with air.
The mucus helps the snail move more easily and protects it from rough or sharp surfaces. This mucus also allows the snail to stick to surfaces, even while hanging upside down.
