Unconsciously, the day is coming to an end. I believe everyone has gained a lot on this day. It's time to take the time to keep a diary. But I found that I didn't know what to write. The following is my diary of observing snails. Welcome to share.
Watch the snail diary1it's sunny on Thursday, July 20th.
In class, the teacher left homework for us to observe snails. So, as soon as I got home, I ran to the garden to look for it, but I couldn't find this little thing. Finally, with grandpa's help, I found two lovely little snails in a wet corner.
It was novel to hear the teacher talk about snails in class. Now that I have seen real snails, I should observe them more carefully.
The snail carries a beautiful and exquisite "small house" on its back, and its soft body is hidden in this "small house". I think they seem to have no bones, because their soft bodies are wet and greasy, and it is hard to imagine anything hard inside.
Snails have a pair of spiral tentacles on their heads, which are always crawling, can be lengthened and shortened, and are very sensitive to external stimuli. If the snail is exposed to the sun, its head will quickly shrink back into its shell and seal the "door hole" with film. This shows that snails are afraid of strong light and heat. Where snails climb, they will leave white marks and shine in the sun. This shows that it needs to use its own body fluids to lubricate and reduce friction when walking.
Where is the snail's mouth? I found a magnifying glass and observed it carefully. I found a small spot on its head, which seems to be its mouth. With such a "mini" mouth, I think snails must eat slowly, so I did an experiment. I put a vegetable leaf on the ground and caught snails for them to eat. I waited for a long time, but I didn't see them eating leaves. I simply put snails and leaves in the box, covered it and slept by myself.
About three hours later, I woke up. I approached the box and was surprised to find that the snail had eaten most of the leaves! Look carefully, there are many small black particles in the box. There is no such thing as putting vegetable leaves, so these particles must be snail excrement. So snails eat in the dark and eat slowly.
Snails are really amazing animals, especially the exquisite "small house" on their backs, which looks lovely and warm, leaving a very good impression on people. However, they love vegetable leaves so much that the vegetable leaves in the garden can suffer! In this way, for us humans, it is not a worrying little animal.
Watch the snail diary Saturday, February 20 weather: cloudy.
At noon today, I happened to meet two small snails in the vegetable field. Looking at their cute little appearance, I couldn't help catching two snails and taking them home in a bottle.
Snails have straight tentacles on their heads. Its eyes seem to grow on tentacles. There is a big and round "house" on its back, which is rolled into a circular pattern. It has no body that can be alive and kicking, so it can only crawl forward slowly. The little snail crawled and crawled, so he stopped crawling. Maybe he's tired. I want to help him. I found a small stick and pushed him away. Suddenly, he huddled in the room, and no matter how I moved, he refused to come out.
Weather on Sunday, September 26th: sunny.
Today I came to observe snails again. I also went to the vegetable garden to catch more snails and let them have a crawling competition. This distance is from one side of the table to the other.
The race began, and several snails began to climb to the finish line. One of them is the fastest. Maybe newborn calves are not afraid of tigers. Look at other snails. Some followed closely, some turned around, and some stopped at the starting line to look around.
No, a bigger snail is going to catch up with the leading little snail. I saw the little snail turn around and run at full speed to the finish line. Finally, the little snail beat all his opponents with his perseverance and won the first place in the competition.
It is so interesting to observe things around you. Do not believe you can experience it yourself!
I have raised many small animals: chubby little goldfish, hardworking ants and slender earthworms. Among them, I like snails best.
It has a "home"-a tornado-like shell, a pair of binoculars for snails-that's its clever eyes and a pair of "hands" holding binoculars-oh, these are retractable tentacles.
One day, it disappeared, and I looked at the Chaoyang platform. The sunny place suddenly flashed, and I remembered that there was mucus where the snail climbed! So I walked along the mucus, which was sleeping in dad's flowerpot. Really naughty.
Snails are also interesting to eat. I gave it a palm-sized leaf, and it didn't seem to see it, so it went to do its homework first. After a while, I went to see it again, and the leaves were gone.
One night, I held my urine in a panic and hurried to the bathroom. Suddenly I found something on the ground. I guess it's a cockroach. You know I'm afraid of cockroaches, so I shouted-"Ah". My father was awakened by my dream, so he came to see it and asked, "What's the matter?" ? I said there was something on the ground, and when Dad turned on the light, I knew it was my little snail. So, I understand it is Nocturnal Animals.
It brings me joy, worry, sadness and joy, makes me feel different every day, makes me like it more, and makes my spare time more colorful!
Today, the teacher asked us to observe snails, so I went to the wet and dark school flower bed to look for snails. "I finally caught a' cute little baby'!"
When I got home, I eagerly released it and began to observe its every move. At first, its body was still in a hard shell. Its shell was brown with some small spots and looked like a snail. After a while, the little snail's tentacles stretched out and inquired about the situation everywhere. Finding no danger, he slipped out slowly. I gently guided it to the stick. Its suction is so great that when the stick stands upright, it won't even fall off. The little snail twisted its body hard, driving the heavy shell together, as if dancing happily.
I put it on the table again, with a small leaf beside it. When the snail started, its tentacles touched the small leaves. I carefully looked at the food in front of me, made sure it was safe, and immediately gulped it down. After a while, many small holes appeared on the leaves. I touched its soft body hard with a stick, and it quickly shrank back into its shell. Taking this opportunity, I secretly put the leaves in the farthest corner. After a while, the little snail came out again, looked around with his eyes and found that his food was gone. So he shook his eyes back and forth on the antenna, and then he climbed forward and slowly climbed forward. Trying to find its food. Careful observation shows that it crawls with its stomach and feet, leaving a deep watermark in the crawling place. I was tired of waiting and said, "Why are you climbing so slowly?" But it didn't give up. It kept moving towards food. Crawling around, it finally got its own food. Its spirit of never giving up deserves our admiration and study.
Observing snail diary 5 during the Spring Festival, I found a strange phenomenon. You want to know what it is? Then let me take my time.
During the Spring Festival, my parents and I came to my grandmother's house to play. My dad was careful that I was bored at grandma's house, so he caught ten snails and let me play in the wild. I carefully looked at these ten cute little creatures, and found that seven snails have right-handed shells, and the other three snails have left-handed shells. They have many colorful stripes and spots on their shells, which are very beautiful.
I put some vegetable leaves for them to eat. However, only one snail left a big pit on the vegetable leaf, and none of the other snails touched it. I asked my father with questions. Dad picked up a piece of chicken and put it in the trough without saying anything. The snail immediately "galloped" and ate it with relish. Dad looked at me blankly and explained, "Snails have all kinds of feeding habits. Some snails like to eat vegetarian food, and some eat vegetarian food unevenly. " "After listening to my father's words, I suddenly realized.
A few days later, I found a strange phenomenon of snails: all ten snails are laying eggs! I think: there must be some male snails and some female snails caught by my father in the wild, but they can't all be female! I looked up the information on the Internet and finally found that there are two genitals in the snail's body, one is male genitalia and the other is female genitalia, so the snail is both a "husband" and a "wife". How interesting!
A little snail has so many secrets. I believe that as long as we carefully observe everything around us, we will certainly discover more secrets of nature!
Observe the snail diary. It's sunny on Wednesday, June 7 10.
When small snails eat, they like to start eating from the middle of leaves. It likes to eat young leaves best, and walks while eating, leaving a small hole behind with shiny mucus on it. Snails pull whatever color they eat, mostly dark green. Once, we fed it purple cabbage, and it pulled out purple poop. When it eats Chinese cabbage, it will have yellowish poop. Its neck can stretch very long, and its shell seems to be falling off. I'm worried about him.
On Saturday, July 20th, it was cloudy.
Small snails often escape from prison and always like to run out of the house and explore the outside world. Once it slipped out, and three days later, we found it on the refrigerator. He curled up in the shell, dry and motionless. Mother soaked it in water and it slowly woke up. Although it experienced a crisis of life and death this time, it still has an evil heart and wants to go out and explore the world. However, every time it climbed to the outer wall of the box, it was carried back by us.
1Saturday, October 26th 10 cloudy.
The little snail got into the soil, so we couldn't see where it was. Its shell is like a small stone buried in the soil, which is its protective color and is difficult to be found by natural enemies. Now that the little snail has grown up, he needs a deeper clay pot to bury it all in the soil.
165438+1It will be sunny on Sunday, October 3rd.
Now that the weather is cold, it will be winter. I wonder if the snail will hibernate? I am looking forward to it. I will continue to observe.
Observe snail diary 7 My parents accompany me to find snails whenever they are free these days.
We searched in the flower beds of the community, the lawn of the College of Arts and Sciences, and the haystacks by the river around the city, but we never found the snail. When I learned that many students in my class found snails, I was very sad and wondered why I didn't find them. Is it my bad luck?
My mother smiled and said to me, "Maybe we are unlucky, but maybe we have found the wrong place and method. If we can look in the vegetable fields, if we can look after the rainy places, and if we observe more carefully, maybe we can find snails. Therefore, it is very important to pay attention to methods when doing anything. " Yes, I can't complain about bad luck just because I can't do something well. This is not right.
Just when I was disheartened, my father and I accidentally saw a snail in the haystack near Golden Times Square this morning. I was very excited. Unfortunately, this is a snail without a nest. I wonder why it doesn't stay in the nest like a snail's shell. So I can take it home for a few days. This snail has a long neck and a long tail. Its eyes are on the antenna, like two searchlights. It gets up slowly, but it keeps climbing.
I didn't catch the snail and go home. I hope it can find its own shell early and give it shelter from the wind and rain.
Observe snail diary 8 20xx 10 June 14 Friday sunny.
Observe snails
Tom Zheng
Today, the teacher caught a snail in the science class. Let's observe its appearance, movements and characteristics, and which part of its body it crawls with. I caught a snail and put it on a piece of glass prepared in advance. I picked up a magnifying glass and observed it carefully. I found that the snail's shell is spiral, the mouth of the shell is a little transparent, but the back is opaque. When someone invades it, the snail will retract its head into the shell to protect itself. When it is still, it can have a good rest in the shell. It's killing two birds with one stone! It has four tentacles on its head, and the two small black spots on the tentacles are its eyes. I gently touched its eyes with my hand. It seems that it saw the bad guy and ran back at once, but after a while, it stretched out again. I also found a small hole in the snail's head. The teacher told us, "this is its mouth. There are more than 30 thousand small teeth in its mouth, which can even bite a paper box." Although this snail is small, it is really amazing!
The teacher also told us: "The place under the snail's shell is its abdomen." The middle of the abdomen is thick and thin, and the abdomen has movable abdominal feet. "I also found that snails leave a long liquid after crawling. After the teacher's explanation, I also understand that it secretes mucus, which can reduce the friction when crawling, prevent its ass from being injured, and is also conducive to progress.
After a class, a little snail let us learn a lot of knowledge. I found that as long as we observe attentively, we will find many interesting things and the mysteries of nature!
Observing snail diary 9 I observed my snail: its whole body is spiral, like a small screw; Its shell is hard, the color is grayish brown, and there is a circle of patterns on the shell, like tree rings; Its body is smooth and soft like a sponge; Its head is very small, with two pairs of antennae, one long and one short. The long one has eyes on it, and the short one has a small circle in the middle.
I made a home for the snail in a paper box and put some leaves in it for it to eat. You always have to take a shit after eating.
Snails shit every few hours, so where does the shit come from? I have observed it for a long time and know that shit is pulled out from the pores of snails.
I have a new question: How do snails eat? With this question, I looked it up online.
The snail's mouth is on the ventral surface of its head. It has a strip-shaped toothed tongue with many small teeth arranged neatly on it. A toothed tongue can stick out of the mouth to scrape food.
Snails are omnivorous and have many hosts, which not only harm green leafy vegetables, but also harm many vegetables and crops such as Cruciferae, Solanaceae, Leguminosae and Cucurbitaceae. Both seedlings and adult plants will be hurt. Snails only eat mesophyll when they are young and leave the epidermis; Older individuals scrape the leaves and stems of plants with their tongues, grind them into small holes or even gnaw off the stems, or the leaves are shapeless, notched, or have residual veins, which can cause seedling shortage and broken ridges in severe cases.
One day after observing snail diary 10, it was going to rain. I was walking home when I suddenly saw two snails, one big and one small, on the grass. Out of curiosity, I took them home carefully. I looked at the two snails and found that the big snail was not as much like a big conch as everyone thought. Small snails are a bit like. There are two pairs of antennae, one long and the other short. On which pair of long tentacles do the eyes grow? The shell is round.
In recent days, I have often stared at snails. I find snails lazy. Very large snails often lie motionless on the small box, and also land on the lid, motionless. Once, I observed it for half an hour, but the big snail refused to move. I was really impatient, so I put two vegetable leaves in to attract them. But they just ignored me! Snail's shell is too thin, the human body moves slowly, and its tentacles can stretch. With a gentle touch, the little snail immediately shrank into its shell. I watched the little snail to see if it ate the leaves I prepared for them in advance, and found that they touched the leaves and left. I'm angry and chilling. After a while, I couldn't help watching snails. I see a hole in a leaf. Soon, the cabbage Ye Quan was eaten by two snails.
Snails usually go out for theme activities at night and like dark, humid and cold natural environment. It tends to gradually climb onto the leaves of Chinese cabbage, reach out and taste it slowly, and then gradually start eating.
Diary of snail observation 1 1 Teacher Science Yu left us an autumn assignment-observing snails and keeping a diary.
On the way to Ningbo, I rummaged through the grass by the roadside and finally found four small snails. I put them in a box, covered with wet soil and leaves, and covered with a layer of plastic wrap. This is the snail's home.
Along the way, I carefully observed them and found that the snail's body was completely spread out by three centimeters. They also have two pairs of antennae and a Zhang Yuanyuan mouth. Snails climbed up when they saw a place where they could "walk" backwards. Through the plastic wrap, I found that snails don't walk with their feet. What does a snail walk on? I went to Ningbo's computer and looked it up. It turns out that snails have a movable meat foot, which is equivalent to a snail's foot. Where they "walk", they will leave a white liquid.
Suddenly, I saw the thin and long tentacles of the snail, so I touched them with my fingers through the plastic wrap, and the snail immediately put its tentacles into its sticky and soft body with a whoosh. I can't help laughing. Look at its timid appearance, it really looks like a "little puss-head".
I really like the innocent look of the little snail.
Watch the snail diary 12 When I came 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 when it touched. 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 it touches something, it will retract its head.
According to the teacher, this seems to be the pressure that biology should have. When a snail is stimulated, it will shrink into its shell. After a while, his soft body was almost invisible. 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, and 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.
Observing Snail Diary 13 Snails Some time ago, the science teacher asked us to bring snails, so I asked my grandfather to catch some snails from the countryside and keep them in a cardboard box, and observed them while raising them, adding a lot of new knowledge. When I first caught it, the snail was motionless in the box. Maybe it's the new environment. The snail seems a little nervous, which makes me worry about whether it is alive or not! It was not until the next morning that it "came alive" and climbed to the top of the box, which gave me a chance to observe it in all directions. I found that snails have two pairs of antennae, one is long and the other is short.
When I gently touch it with a stick, its tentacles will retract into its head, and when there is no danger, it will continue to come out and do its own thing. I really envy its carefree leisure! Snails like to eat leaves of vegetables such as cabbage and radish. Every time I feed them, they seem to be very picky about food, hiding their heads in their shells and refusing to come out to eat. But after a while, I went to see them again, and the leaves were full of holes. Oh, they are afraid of eating, and they are shy! In addition, if you put it in water, it will stick its head out of the shell in a short time. When I take it out of the water, it will raise its eyes I also found a pair of small feet under its shell, which snails use to move. In addition, I also checked the information and learned that snails belong to mollusks. This is the first time I have seen such a small animal. It can be seen that there are endless mysteries hidden in nature, waiting for us to dig!
Observe snail diary 14 snail, one of the most peculiar creatures in nature. I first saw snails when I was very young. At that time, I thought it was an ordinary bug. Later, after reading the snail introduced in the encyclopedia, I realized that although it looks cute on its soft back on the house, it is a pest with 1200 teeth in its mouth, and I suddenly felt that the snail was wonderful.
One afternoon in late summer, after the rain in Chu Qing, the weather was extremely wet. My mother and I walked downstairs and saw three big snails. These three snails are bigger than usual. They are all crawling in the land with a big hard shell on their backs, so slowly and leisurely, but I find that there is a layer of liquid on the ground they climb, like a kind of mucus secreted by their bodies, just like the shoes we wear. In order to protect myself from harm, I picked up the snail and found a small white spot under its shell, not its tail. Snails have no tail. This is a snail's foot.
I found a twig and touched it with its tentacles. The snail immediately shrank its whole body into its shell. I think the small tentacles on the snail's head are very sensitive, soft and sensitive, just like human eyes and hands, which are covered with cells. So when the tentacle touches something else, it will quickly change direction and route. Tentacles have played a great role. Look, it's soft. It's hard to imagine how long those 1200 teeth are.
Ah, how wonderful nature is, among which snail is really a strange and lovely little animal!
Observe snail diary 15 Snails and slugs belong to mollusks, but snails have an extra "home". Do you know how the name snail came from? Hee hee, it's actually very simple, because the snail's head has a pair of tentacles that look like a horn, so it's named "snail".
When I was a child, I used to catch snails and even compete with other children to see who could run fast. But I have always wondered: why is there a line where snails climb? In order to find out, I have been watching snails, turning them over and even taking them out of their shells. I have been obsessively observing for more than a month. I finally got the result with a lot of things.
Through a month's observation, I found that there are a pair of eyes at the top of the antenna on the snail's head, but I can't see far under strong light, and I can only see further things under weak light. So it always comes out at dusk and night. Snails are very weak. When crawling, a greasy mucus is constantly secreted from the foot gland to reduce the friction between the foot and the road, which is beneficial to speed up the movement of the foot. This mucus dries when exposed to the air, and then glows under the light, so there are always shiny marks on the ground where snails climb.
I am glad to find the secret of snail, because it lets me know that as long as I have confidence and patience in things, I can find many secrets from it.
