I have seen snails have eyes before. Why didn't I see them? I went up to have a look, but as soon as I walked past, they shrank their heads into the house like turtles. I couldn't observe it at all, so I caught a few and went home to observe it carefully.
The first place I explored was the mouth of a snail. I put some cabbage leaves for snails. The first snail poked a little head out of its shell and climbed onto the cabbage leaf. I quickly picked up a magnifying glass and began to observe. The snail first touched the cabbage leaves with his two "long beards" and ate them with relish with his small mouth.
There are no eyes at all. It seems that the first exploration goal-failure.
I thought to myself: Hey, where are the snail's eyes? So I'm going to solve this mystery and continue to explore. A little snail also came out to look for food.
I quickly began to observe. I finally began to observe the snail in front of me. I saw two pairs of tentacles on the snail's head, one big and one small. There are two small round beads at the top of the big antenna, which are its eyes.
The second exploration goal-success. Ha ha! I finally found the snail's eyes.
It turns out that the eyes of snails grow on tentacles, and the mysteries in the world are really endless.
I found the snail's eyes. There will be silly snails crawling around on rainy roads, fallen leaves and in front of houses.
It's ridiculous to see them crawl slowly, with a little trouble, and retract their tentacles into their shells like turtles. Laughter leads to laughter, and a question mark can't help floating in my mind: the book says that snails have eyes, and it doesn't just rely on tentacles to tell the direction.
But where are the snail's eyes? Why can't I see it? So I caught some snails, put them in a glass jar, and dropped some cabbage leaves to see where the snails' eyes were. The first exploration target is the snail's upper body. I think snails' eyes should be around their mouths like other animals. I hid by the cupboard and secretly observed the "sleeping" snail in the glass jar.
Soon, a bigger snail poked its head out of the "door" and its two tentacles came out. I saw it slowly climb onto the vegetable leaves, slowly looking for the tender leaves, and then slowly eating.
Seeing it eating with relish, I quietly straightened up and looked at it with a magnifying glass. But under the magnifying glass, there is nothing like eyes around the snail's mouth except tiny stripes. The first exploration goal-failure! My second exploration goal is the snail's tentacles, because when it eats leaves.
You must touch it with your tentacles first. Another snail "woke up", and I happened to verify whether every snail touches it with its tentacles when eating.
Sure enough, as I expected, the snail climbed onto the vegetable leaf and reached out and touched it. I zoomed in to observe its tentacles.
I saw two round eyes at the top of the antenna-like other animals, there was a small black spot in the middle of the whites of the eyes. I have repeatedly observed other snails and the results are the same.
The second goal is exploration-success! I'm glad I found the snail's eyes, at the top of the antenna.
3. Describe the snail 300 words snail
My mother bought a small snail in the market the other day. I am very happy. I filled an idle fish tank in the corner of the balcony with sand, like a soft and comfortable golden carpet, and then put snails in it.
I go to see snails after finishing my homework every day. Sometimes it hides its head in a hard shell, so I can't get out. Sometimes when it feels comfortable, it stretches out its long body as long as 10 cm and climbs on the beach.
Snails carry a spiral shell on their backs and like to live in a humid environment. They sleep during the day and go out at night. Most afraid of direct sunlight. It likes to eat vegetables, weeds, melons and skins.
Snails are really interesting. If you cover the fish tank, it will immediately move its slow body and climb to the top of the tank. It won't fall. Why? It turns out that snails rely on a kind of mucus secreted by their bodies, which makes them firmly stick to the cover and move more easily on the rough ground. This is my lovely little snail. It accompanied me through every happy day.
I have two small snails which were given to me by a good friend of mine. They are very cute. After dinner today, I am free to lie on the table and watch snails.
I observed that the whole body of a snail consists of eyes, mouth, feet and shells. My snail has a spiral shell. My mother told me that snails have various shells, such as pagoda, gyro, cone, sphere and so on. Snail's eyes grow on a pair of antennae at the back of the head. There are a pair of small antennae in front of the head. When lightly touched, it will quickly bend into the shell. There is a small opening under the antenna. When I was watching, I suddenly saw the little snail eating vegetables. I shouted, "Come and see, come and see, the little snail has eaten vegetables, and the little snail has eaten vegetables." I am particularly excited at this time. Not long after, I found a big hole in the whole leaf. I said to my mother, "mom, mom, the little snail eats faster than me!" " Mother said, "Do you know where snails excrete?" "I really didn't find it." Snail excrement is called stomata near the breathing hole. It will leave feces on itself through the abdomen and mucus, and finally leave feces on the ground. Please take a closer look. "My mother said.
By observing snails, I learned a lot of new knowledge. I like my little snail.
Write a composition of about 400 words for a little snail. This morning, my family came to the square to play badminton. I found a small snail during the break. I studied it carefully. It has a hard shell, two pairs of tentacles on its head, and a small black spot on it, which is its small eyes. It walks very slowly, and its small house shakes because it walks on its stomach.
Suddenly I found that the place where the snail walked was full of mucus. Why? I went to ask my mother, and her mother said, "A snail's stomach is like a sucker, but to suck the sucker firmly on a smooth surface, there must be some liquid to prevent air leakage." Snail sucker is no exception, the liquid viscosity is relatively high, and it can stick to objects to prevent falling. The little snail crawled forward slowly, trying to climb to a comfortable place to sleep. I watched its soft body crawl slowly forward and wanted to help it. I just touched its hard shell and the little snail got into it at once. I was frightened by it, so I found a wet place to put it down and squatted there, waiting, waiting, waiting for the snail to come out of its shell.
After a while, the snail made an action. First, its small house shook, and then it carefully put out two pairs of tentacles to spy on whether there was danger around it. If everything is safe, it will stretch out its weak body. When I saw it, I looked carefully and saw the little snail carrying the heavy shell and moving forward step by step. Climb, climb, climb, climb to the edge of the flower bed, climb into the soil and disappear into the flowers. Hearing the cries of my parents, I froze and reluctantly left the snail.
6. Composition about Little Snail [Composition Little Snail] Wednesday, July 30th, sunny 1 1.
In the evening, I saw my father peeling loofah and writing a composition about snails. I was surprised to see a small snail on the loofah.
This snail is almost less than a centimeter. I think snails should have a name. I'll call it weak. Because I touched its tentacles, it shrank in. I think it is fragile and timid, so I call it cowardice.
I put the little snail-oh-no, the weak one in a plastic cup, and it crawled around excitedly. It looks lovely!
However, at night, it will shrink in the shell and never come out again.
Seeing the little snail so naughty, I thought to myself, what a naughty child.
Snails are naughty and lovely, and I like them very much.

7. The composition of the little snail 230 words In the evening, when my mother was cooking and washing vegetables, she found a little snail in the leaves. My mother is holding a small snail, and the small snail keeps moving in her hand. I found a plastic bottle, put the snail in it, and put some water and vegetable leaves in it. I put a few holes in the bottle cap to let the little snail breathe fresh air, and the little snail's home is ready.
I watched its movements while doing my homework. The little snail may always want to climb out, but when he sees the leaves, he can't help but stop. Two long tentacles stretch and contract for a while, and two short tentacles can't be seen without careful observation. The little snail climbed up step by step and remembered a song "Snails and Orioles". I sang to it in a low voice, hoping it would understand the song.

In the morning, I had a quick breakfast and had a rest. Then I took a small step and went to the park to play leisurely.
In the park, I walked slowly to the lawn and fell asleep. "Wow, how comfortable! I haven't felt this way for a long time. If only I could stick to this carefree life. " Because: I like this life best. I overheard a small, faint voice, as if to say, "Wow, you are really cruel, so heavy, you really crushed me." I got up at once, and when I saw it, it turned out that a weak snail was pinned down by my big palm. I was so ashamed that I almost sent a living little life to the grave!
I said to him, "I'm sorry!" He seemed to understand what I said and touched me with his two small gold hoop bars as soft as the Monkey King's, as if to say, "Never mind." Then, I immediately ran home and took a big box and some: Chinese cabbage, what snails like best, and so on. I immediately ran to the park and came to the place just now. "Thank God, that little snail is still there!" Or I ran away for nothing. "I carefully put the snail in the big box and then put some food in it. At first, he seemed a little scared. He felt that his tentacles had no "enemy", so he gave birth to a small head and began to exercise. He climbs very slowly, and there is mucus everywhere he climbs. He climbed beside the Chinese cabbage and leaned on it without eating. He doesn't know what he is doing, as if he were sleeping.
How time flies! It's almost noon. I have to go home. I can only say to him, "Goodbye." He seems to really understand what I said, shaking his tentacles, as if to say, "Goodbye!" "I can only go reluctantly.

I found a snail the size of a thumb on the grass the other day.
Snails have long eyes and a small mouth. There is a small house on its back under its head, probably because there is no place to hide when it rains. I quickly took it home.
Snail regards our flowerpot as grass. It likes to eat vegetable leaves. When I fed it leaves, it slowly approached the leaves and smelled them, huh? Snails have noses? Where is its nose? The science teacher told us that the two small tentacles next to its eyes are its nose! Look, the snail got the information about the food and began to suck the juice of the vegetable leaves with its small mouth.
Snails like to live in wet places. If you put it in a wet place, it will stick out quickly. If you put it in the sun, it will quickly retract its head into the shell.
Snails have a very strong crawling ability. One morning, I went to see the snail and found it was gone. I can't find it anywhere. At this moment, it suddenly occurred to me that when snails crawl, they will leave silvery traces. If I follow its crawling track, I will definitely find it. After searching and searching, it climbed onto the roof and stayed in its small house.
This is my lovely little snail.

9. An ant's eyes write a 450-word composition. It took a lot of effort to catch a big grasshopper. I hurt it and put it in the ant's hole for dozens of centimeters.
After a while, I found an ant "scout" found food. It ran back excitedly and came face to face with another ant. They all hit the corner and went back to the hole. I walked away for a while and came back to have a look. Wow! A group of ants crawled on the injured grasshopper. The grasshopper struggled. Several ants fell heavily to the ground, but they quickly got up. After a while, more ants climbed up and grasshoppers flew. However, because there were too many ants on its back, it fell down in less than one meter. The grasshopper was exhausted by the ants and had to surrender. Finally, the grasshopper was "chopped into pieces" by ants.
The ants lined up the winners in a long queue and moved back to the cave one by one. After the fierce fighting, my legs are numb. I stood up and patted my leg. I wonder, how did this little ant deal with this big grasshopper? That's right, it is unity.
From this, I realized a little truth, as long as we unite as one, nothing can stop us. Just like this ant, this United collective.
I found the unity of ants. I like ants, not only because of their industrious and simple character, but also because of their spirit of helping each other and forging ahead in times of crisis. I remember once, several ants were crawling on the wall in a hurry.
On impulse, I poured water from a teacup and threw it at the ants. They were frightened and fled everywhere. I poured water on them again, and they were all wrapped in water drops of different sizes.
Stubborn little ants are trapped in the water, but they still don't give up the chance to escape. They spread their legs thinner than needles and tried to climb to a dry place, but it was too late, and the water droplets as big as beans stuck to them like glue, making them unable to move.
At this time, I saw them huddled together, holding hands, fighting bravely, and finally rushed out of the tight encirclement, exhausted, lying back to back together, encouraging each other. After a while, the long line lined up again.
Their team walked in the direction of the cake crumbs left by the rats. Then, the cake crumbs as big as broad beans disappeared. I moved the cake crumbs to another place, and the ants were not to be outdone. They found food at once. At this time, a group of ants came, and the cake crumbs disappeared from my eyes at once.
I looked at this group of ants and sighed. It is true that ants with big grains of rice are sometimes stronger than some people. I discovered the secret of snails. One afternoon, it was very sultry. I was playing with my father's "baby"-orchid on the balcony when I suddenly saw a small snail climb up a leaf.
"Are snails beneficial insects or pests?" "Why do you leave a long line when you climb?" "Where are the nose and eyes of the snail?" This series of questions appeared in my mind. So I decided to do an experiment myself to find out these problems.
"Snails are beneficial insects or pests?" I put cabbage, steamed bread, mosquitoes and so on first. In front of some snails I caught. They are probably hungry and climb on their favorite food. I saw that snails chose cabbage leaves to eat, but they didn't smell other foods. In a short time, the snail ate all the leaves of the cabbage and could be judged as a pest. "Why do you leave a long line when you climb?" In this question, I first draw the snail's head with a leaf, and then gently touch it under my head with my hand. I didn't expect my head to retract immediately. what can I do? I was a little discouraged. My father came up to me and said, "Why, you are discouraged by such a trivial matter!" " ! Do you want to be a scientist when you grow up? "I was so excited by what my father said, and I was excited again.
Wake up the sleeping ants. The ant heard someone knocking at the door and opened it. The cricket came out and begged, "I'm starving. Give me something to eat! " The ant replied sarcastically, "Mr. Cricket, please sing and dance!" " "This story illustrates the value of ants' hard-working reserves, and also illustrates the truth that" if there is no future, there will be near worries ".
Ants are United and hardworking. We should learn the spirit of unity and progress and the qualities of hard work and loyalty. I leaned quietly under the big tree, and a small black ant caught my eye.
He walked and walked, but he couldn't find his home. Is he lost? Or does he know the way, but his home is too far away? Suddenly, another little ant came running. He should be his family. Otherwise, how could he touch the corner with him and move forward together? Follow them and finally find their home. After a while, he led a large group of ants out again.
I saw them lined up, striding along E5A48DE 588B6E799BE5BAA63133337383832, through a forest of grassland, hills and mountains. They crossed the mountains and came to a small piece of bread.
Oh, that little ant found food! Soon, one by one, they lined up neatly and went home. They move again and again. Before long, a piece of bread became smaller and smaller until the bread was gone.
This little ant walks in the front as if he were a captain. On my way home, I met many companions. They greet each other, but their team has never fallen behind or dispersed.
They are like an army that went to war and returned home in triumph after victory; They are also like a team, performing for forests and hills. It turns out that the ant tribe is so United! It sank in the west and the dark sky woke me up. Ants are really great.
