Interesting facts about SNAILLLLLL~~~~~~~

I was looking up for some dumb facts on the internet a few days ago, and I found out that a snail can sleep for three years at a time if they want to. Isn't is quite amazing cause no other living creatures do not sleep for three years at a time. Well, maybe they can't. Anyway, the reason that I found why snails sleep for three years is because of the climate change. Most of the time, snail sleeps and since they sleep most of the time, it is quite rare to see snails appearing at day. The reason why they do not appear in the day is because they need moisture to live and to save moisture, night time should be the favorite time for them to move since in daytime, they have to use more moisture than nighttime. Another reason is to protect their shells and I do not know is this.....
However, when they wake up at night, they move really slowly and cautiously, munching on whatever vegetation they can find or eat. Then how do they find food when they do not have eyes but tentacles? Well, luckily they do have eyes on the end of their tentacles but when they find food, they mostly rely on their sense of touch because they cannot hear and have very poor eyesight 
(I am not sure if they have poor sight because I searched in the internet, why do they have eyes and where do they use that and all I have found was that they do have eyes and for land snails they have on the tip of their tentacles. They said snails move their tentacles up and down and that action helps them to get the best view.). 

Sometimes, you will see that when you touch their eyes, which is end of their tentacles, they will put their eyes back in or they just draw their eyes into head. That is because first, if you touch snails' eyes, they feel pain just like when somebody touches our eyes since there are dirts in humans hand and we just can't see them. Second is that when snails feel threatened or danger, they put their eyes into head for protection. What's quite interesting is that they can even withdraw one tentacle at a time if they want to.

Another interesting fact about snail is that they do not have to find their mates unlike us. Isn't it cool? Because we, humans, have to find our husbands or wives in order to have our children but snails can just lay about 30 eggs at a time by themselves! How cool it is!! But you know what? I do not care because that doesn't affect my life, do they? Let's just go to reasons why snails are like that. Basically, it's because they are hermaphrodites. Each snail can lay about 30 eggs like I just said. They place their eggs underneath a stone for the eggs to hatch.

They produce a slimy gel, that covers the opening of its shell. That slimy gel is one of the reasons why snails do not get hurt even they cross the edge of a razor or other spiky materials. When snails crawl, there is a trail of slime left behind. Anyway, they can even climb up the walls upside down, because of the slime that is produced by their bodies. It would've been great if humans can also produce slime that makes humans to climb up the walls upside down without any problems.

This is the last fact for here today and it's really COOOOOOLLLLL!!!
When the weather gets uncomfortable for snails, they bury themselves underground for warmth and then they make a really small hole that allows the air to come in and out. They also produce slimy gel that covers their opening shall like I just said for protection. They stay in the ground until the climate gets better. However, if the weather does not get better or suitable for snails to live, they even hibernate or sleep for three to years until the weather gets suitable for them. Isn't it surprising?? There should be no humans can beat this record. Sleeping for three years......
