I was surprised to hear the teacher talking about snails in class. Now I see a real snail, and I want to observe it carefully.
They carry a beautiful and delicate "little house" on their backs, and their soft bodies are hidden inside. I put them in a small box and began to observe.
I found that snails seem to have no bones and their bodies are soft and wet. The head has a pair of spiral antennae, which are very sensitive to external stimuli. If they are exposed to the sun, they will soon come out of the "doorway" closed with film, which shows that snails are very afraid of direct light. Where snails climb, they will leave white marks and shine in the sun. This shows that it needs lubrication when walking.
But where is the snail's mouth? I found a dot with a magnifying glass. I think snails must eat slowly. So I did an experiment. I took a vegetable leaf and put it in a box, and caught a snail to eat. I waited for a long time and didn't see it eat leaves, so I closed the box and went to take a nap. When I woke up, I was surprised to find that the snail had almost finished eating the leaves. But I've never seen it eat. I think it may eat in the dark. I took a closer look and found that there were many small black particles in the box, which I didn't find when I put the leaves. It must be snail shit. Sleeping for about three hours shows that snails eat in the dark and eat slowly.
Snail is really a magical little animal, especially the "small house" that protects it on its back, which leaves a very good feeling for people.
Today, the teacher asked us to keep an observation diary. I blinked and thought about what to write. Ah, I found it! Just write my little snail!
When I first brought those little snails back, I put them in a plastic box, and I made some holes in it. This is their house!
My little snail has two long tentacles, each with a small eye. As long as you touch its tentacles, it doesn't know where it is connected! Its body is sticky, and it is not afraid to climb backwards or sideways. But they are all downright cowards. The slightest noise scares them into hiding in their shells and they dare not come out. I smiled. Slowly, they feel safe and come out of their shells to play. "These clever little snails will still play dead." I thought to myself.
They all have a bad habit, that is, defecating everywhere. Whenever I come home from school, the first thing I do is to look at my little snail. Every time there is shit on the lid, it's disgusting! I have to wash them, tidy the house and change the leaves. It's really troublesome.
I want to do an experiment to see if snails are afraid of water. I added some water to their house, and the snail was not afraid, but crawled around happily. So I know snails are not afraid of water.
I have some smart and lovely little snails, and I will feed them well!

Finish writing calligraphy in the morning and go to the kitchen to wash your hands. Hey, there is a cute little snail on the wall above the pool. This little snail looks strange. It seems that it has no bones, but it is full of muscles. It carries a pale yellow spiral house on its back and has two pairs of antennae like antennas on its head. It's amazing to see it climb up slowly with its flat sucker-shaped feet!
Then I asked my mother curiously, "Mom, why is there a small snail on the wall?" "Maybe it's on the vegetables your grandmother sent." "Oh, that's it. I thought it was a small snail climbing up from downstairs. " After that, I happily brought a small box, gently grabbed the snail and put it in the box. The little snail was frightened and shrank in the small house, motionless. So I gave it water to drink and green leaves to eat? Hey, this little thing is ungrateful. I'll try my best.
"induced", it still refused to stick its head out, and I was anxious not to eat or drink! Until the afternoon, the little snail was still shrinking. Well, if you go on like this, you will definitely die. Looking at the poor little snail, I said sadly to my mother, "Mom, I think I'd better let the little snail go." It may miss its mother. Good boy, that's right. Small snails belong to nature. "My mother stroked my head and said with a smile. Later, I sent the snail back to the square grass. That wonderful little snail seems to be refreshed at once, as if waving goodbye to me: "thank you, little master!" " After a while, the little snail disappeared into the grass.
Snail Diary Model essay 5 September 25
Tuesday is fine.
I found a snail on my way to school. I learned about snails in science class, so I wrapped it in leaves and took it home for careful observation.
At home, its body curled up in the shell and refused to come out. It's probably just frightened. After a while, it came out carefully, just sticking out its head, as if it saw me, and immediately hid. After a long time, it seemed unbearable and poked its head out again. I was afraid of scaring it, so I watched it quietly in the distance.
Snails have two pairs of antennae, usually one long and one short, like four antennas, which keep shaking as if transmitting signals. Can you guess what these two pairs of antennas are for? Tell you, its tentacles are not used to transmit signals. There are four small eyes on those four antennas!
The shell of a snail is snail-shaped, with some irregular patterns on it. Its shell has some gland cells, which can secrete a liquid to protect the snail's soft body.
When the snail moves forward, its head stretches forward, stops on the ground, and then drags its heavy shell forward with the strength of its body. If you look closely, you will see a winding line behind you, which is the trace of snail crawling.

Thursday is fine.
The second time I went to see the snail, it had climbed about 5 cm. It seems a little hungry. I want to feed it something, but what should I feed it? I found the answer online. It turns out that snails eat some weeds, such as melon skin. I put it on a melon skin and it immediately ate it with relish. It sucks food into its mouth with its teeth. It has the most teeth in the world. Although its mouth is only the size of a needle tip, it has 25,600 teeth. It chews with its lips, chews up food and swallows it. This is how snails eat food.
I have observed this snail for two days. It can't follow me anymore. If it follows humans, it will die forever. I decided to release it and return it to the embrace of nature. I took it to the lawn in the yard and let it find its own home.

very good
There is a small snail in my flowerpot. It carries its big house around all day. Every time I look at it, I find that when the snail comes out of its shell, its ass always comes out first, then its head comes out and crawls forward slowly. Every time it rains, it has to climb on the screen window, because it likes humidity.
Once, when I was watering the flowers, I saw a small snail again. I found a shiny white line on its path. Why? I ran to ask my mother, and her mother said, "There is a kind of mucus on the snail, so there is a white line on his way."
I am very happy because I have learned a new knowledge.
Snail Diary Model essay 7 Snail is an insignificant little guy in the animal kingdom, but it brings fun to our life.
You see, the teacher put a cup with snails on the platform in class. Every little snail squirms, sticking its neck out from the edge of the cup, as if observing the movement around it; Some move their tentacles as if they were bowing to us; Others lowered their heads and pursed their lips, as if to say: boring, not even delicious.
After a while, the teacher put all the snails on the leaves. You see, those little snails who were pouting just now soon ate with relish! There is a slightly bigger snail. At first glance, its two tentacles tremble, as if greeting its classmates. The teacher touched its antenna with his finger and it shrank back at once. I thought: Is it afraid?
In the blink of an eye, the students found that the big snail had disappeared just now, so everyone rushed to look for the naughty big snail. Wow! It turned out that it dared to sleep under the projector on the edge of the podium. The teacher caught up with him. You see, he is too shy to lift his head, just like when I do something wrong.
It's fun to have classes with snails.

I keep some snails at home. I put them in a feeding box. I put some water and soil in the feeding box, and there are many leaves. In order to let the snail breathe better, I also inserted many small holes in the box cover. While observing snails, I took a snail out of the box and put it in my hand to let it crawl by itself. Snails have black eyes and grow on tentacles. The book says that snail's eyes can only vaguely see very close things; The body is flesh-colored, it feels soft, and it will shrink into the shell when it feels. Snails crawl on their feet, and their feet are called abdominal feet, which move in waves. When climbing on me, it makes me itchy and comfortable.

Today, I found that snails didn't eat all the leaves I put in the feeding box, but these are all the leaves they used to like to eat. It suddenly occurred to me that I had never seen a snail eat leaves on the ground before. It seems that I will only climb to the grass or dwarf trees and eat leaves. Maybe my snail is the same. But how can we achieve this effect? I thought about it and put the leaves in the small hole in the lid. It seems that leaves are growing, so they will eat leaves.
1Sunday, October 2, the weather is fine.
Today, I found that snails really ate leaves, but most of them ate green things outside the leaves, leaving a white net-shaped leaf part where they ate. I also saw some small black spots on the lid of the box. I took a closer look and found that it was snail poop. Suddenly, a snail shit again. I thought the place where snails shit was at the end of their bodies. This time I saw it clearly. It was pulled near the shell mouth. Alas, I have to wash the feeding box again!

Today, after I took the snail out of the feeding box, I found that there was a transparent film on the mouth of the snail shell, and my body was shrunk in the shell. The book said that a few drops of water on the mouth of the shell can make the snail come out, so I took the snail to drop water, and if so, it slowly came out. I found that when it came out, it was like a little heart beating in the shell. When the snail comes out, I just hold its shell and its body will move. Maybe it wants to find a place to stick, as if it is insecure!
1Tuesday, October 4th, the weather is fine.
Today, I found that I touched a snail, but it just retracted its tentacles into its body, and the rest of its body did not shrink. I think maybe the snail has contacted me too much, so it is no longer afraid of me. I pushed it a few times, but it still didn't shrink back into the shell. Snail shit has changed a lot. Could it be that it is familiar to me? Alas, snails can do anything as long as they are in close contact with people.
I wanted to watch insects today, but I couldn't catch them. My mother had to help me catch three snails. I am very happy, but I dare not touch this snail, so I asked my mother to help me put it in the insect box. Snails are not insects, they are mollusks. There is a magnifying glass on the lid of the worm box, which can observe snails well.
Snails have two pairs of antennae on their heads, and the long pair of antennae have snail's eyes. There is a shell on the back. Its shell going abroad is spiral, and the spiral is right-handed. It crawls on its stomach and feet.
The snail diary model essay 10 went home today. I saw a snail in front of my house. I was so happy that I took it home and raised it.
When raising him, I found that there was a layer of mucus where the snail climbed, and the snail's tentacles would retract as soon as they touched it. If a snail is in the dark without water, it will retract its head. If it is put in water, it will retract its head. If a snail touches something, it will retract its head. According to the teacher, it seems to be a kind of pressure. When the snail is stimulated, it will shrink into its shell, and soon there will be nothing to see in its soft body. I also found that the snail has two pairs of tentacles and a mouth. I'm sure he has vision because he can see food and eat it. My snail ate several leaves in a few days, which surprised me. I didn't know snails could eat so much!
Now I know that living things like snails are called creatures, while inanimate things like ordinary chairs and stools are called inanimate things, and I also find that snails crawl very slowly.
We should protect animals, but we can't hurt them, because we can't live without any kind of animals, so we should protect animals, not hurt them. Let's contribute to the peaceful coexistence of human beings and animals.
