Do snails leave marks on glass when they crawl?
Mucus is left behind because there are glands in the feet that secrete mucus. It can reduce friction and convey certain information.

Find food, escape from enemies, reproduce, etc.
snail - movement
Snails are gastropods, and their abdomens are their feet. They crawl by peristalsis of their abdominal muscles. When you see through the glass, there will be a wave pattern on the abdominal feet when the snail is moving. That is because the snail moves forward in a wave manner. Put the snail in the palm of your hand and you will feel like it is being sucked up.
When a snail is moving, its body will secrete a sticky liquid to moisten its abdomen and feet, so that they will not be injured by rough and sharp things, and it can also help them grasp objects. The snail relies on this mucus to slowly move towards the snail. It can climb forward and climb up and down tree trunks and walls.
According to scientists, the fastest speed a snail can crawl is about 12.2 meters/hour. Nowadays, people often use the metaphor of snail crawling to describe a slow speed.
