Why are snails able to move over razor blades without being cut or sliced?


What occurs that prevents a snail from being injured when moving over a razor or sharp object?

In: Biology

Because snails don’t really touch the surface that they are traveling along. They secrete thick mucus, and then Glide along that mucus. The mucus is thick enough that it covers the Razer Blade and protects the snail.

It is somewhat similar to a human throwing a blanket over razor wire before crawling over it. The blanket is enough to cover the razor wire and make it no longer an issue.
