Hey, I have a really stupid question. Can someone maybe tell me EXACTLY how a snail moves. That would be really nice. I need the answer by Thursday at the latest. I hope you can help me. Thanks in advance.

I (14) would like to go to the Aachen Zoo with my student (10). Are we allowed to go alone, or are we too young?
I'm interested in so many things I don't know yet, and I'm even late to some of them because I was always told to focus on school and not work yet. But I only have two and a half years left, and what will I do then? I have no idea. I'll definitely start several…
The worm moves on the sole of its musculosed foot crawling. The mucus separated by glands facilitates the progression: The worm slides over the ground and leaves a shiny track. If you want to observe the movement mechanism, you can simply crawl the screw over a glass pane. It is then possible to see the contraction waves which extend forward from the rear end of the foot.

I would like to add a little to the answer:
There are also snails that have a somewhat different kind of movement, for example the Pomatias elegans, the beautiful land lid snail.
Here you will find pictures and also a video about the movement of these animals:

The extract from the website:
The movement of the land lid screws, which clearly differs from that of a lung screw, as the vineyard screw, for example, introduces, is also particularly important. In contrast to a lung auger, which places its entire foot sole in wave-like movements and thus moves forward, land lid augers move so to speak “two-footed”: They alternately set the left and right longitudinal half of the foot forward.
Hey, thanks to her two. I really need to know that for school.thx
