Why do snails crawl on the wall?
Recently, discussions about natural phenomena have continued to rise across the Internet, with "Why do snails crawl on walls" becoming one of the hot topics? This article will analyze this phenomenon from a scientific perspective and present a structured analysis to readers based on the hot data of the past 10 days.
1. Scientific explanation of snail climbing the wall

Snails crawling on walls are mainly related to the following factors:
| reason | Specific instructions |
|---|---|
| foraging needs | Microorganisms such as algae and fungi often breed on walls |
| Humidity regulation | The humidity on the wall is higher than the ground after rain |
| avoid predators | Being off the ground reduces the risk of predation |
| reproductive behavior | Some species lay eggs by climbing high |

3. Analysis of user focus
According to public opinion monitoring, the public is mainly concerned about the following issues:
| Question type | Proportion | Typical questions |
|---|---|---|
| biological properties | 42% | How does slime help with climbing? |
| environmental correlation | 33% | Why are you so active on rainy days? |
| life impact | 18% | Do you need to clean up the snails on the wall? |
| other | 7% | How high can a snail climb? |
4. Integration of expert opinions
Professor Li from the Department of Entomology, China Agricultural University pointed out:"The wave-like contraction of the snail's gastropod muscles combined with mucus secretion allows it to generate alternating adsorption forces on vertical surfaces. This method of movement consumes very little energy and is a perfect adaptive strategy evolved."This view received over 100,000 likes after being reposted by a popular science account.
