Writing an essay about undersea turtles

1. Look at the pictures and write about the turtle in the sea

Once upon a time, there was a turtle, and his wish was to live in the sea.

One day, he saw a Chinese sturgeon coming back from the Yangtze River estuary. The sturgeon said: "There are rare animals and plants in the sea. Do you want to see them?" The turtle said: " I really want to see it." The sturgeon said, "Just walk along the Yangtze River. You will reach the sea at the end."

The turtle said, "Thank you, bye." The turtle crawled slowly. After five days and five nights, we finally arrived at the seaside.

"Ah! My God, how big the sea is!" The turtle was very excited and rushed into the sea. The turtle swam in the sea. He met red lobsters and blue-purple swordfish with big mouths. He was a swimming champion.

There is also a seahorse that swims upright. He is also a war horse in the ocean. There are so many kinds of fish that I can’t even name them.

There are also sea flowers, seaweeds, corals and various plants in the ocean. They are in various shapes, strange shapes, and extremely beautiful! The turtle forgot to go home. He fell in love with everything in the ocean. He gradually couldn't walk and his feet became webbed. Since then, there have been turtles in the world. 2. An essay about undersea animals

As soon as I walked into the undersea world, I saw many strange-shaped corals, some like dragon horns, some like roses... various small fishes among the corals Swim around. Entering the hall, I saw a large group of tourists forming a big circle. I felt curious and walked over. It turned out that people were watching a show. The wedding ceremony of Miss Mermaid and the Prince was being held in the underwater world. The Prince was riding a 300-year-old bird. The big turtle came to pick up the bride, Miss Mermaid, and they swam around in the sea. The mermaid kept waving to the tourists, who all laughed, and then they got on the big shark sedan chair.

After leaving the main hall, I came to the underwater zoo area. There were many strange fishes in it, including tiger fish, angel fish, hairtail fish as long as ropes, and umbrella-like ones. Yao fish... They all have beautiful colors on their bodies, including yellow, black, blue, red, etc. They are really colorful and very beautiful. Among these fish, I like sharks, swordfish and whales the most. The shark was as big as a door panel. It opened its mouth, revealing sharp teeth, and its eyes opened like two big lanterns. The tail of the swordfish has a sharp sword. The whale is as big as a car, and his big mouth is like a cave. Several small fish swam into his mouth unknowingly and became the whale's meal.

The underwater world is so wonderful. It makes me linger. I like the underwater world very much.

3. Write an essay about the sea turtles in the Shanghai Aquarium

This summer vacation, my father and mother and I went to Shanghai for a trip. Shanghai is our metropolis in China. High-rise buildings can be seen everywhere, and the Oriental Pearl Tower opened my eyes even more. Vision. Next to the Oriental Pearl Tower is the Shanghai Aquarium. Looking from a distance, you can see a grand and beautiful building, like a three-dimensional triangle placed on the ground, that is the Shanghai Ocean Aquarium. The Shanghai Ocean Aquarium is the largest in Asia. One of the world's largest marine aquariums, it has the world's longest 155-meter underwater sightseeing tunnel. When we walked into the hall of the aquarium, it was like entering a dreamy underwater world. There are so many marine animals in the aquarium! There I saw many animals that I had never seen before, such as purple seal fish, lion fish... Each fish has its own characteristics, and each fish attracted our attention. So that we all stopped to watch, and Forgot to move forward. There are all kinds of fish, big and small, red and green, yellow and blue, colorful. Some fish even have several colors on their bodies. They shake their heads and tails at the tourists. So affectionate! The first thing I saw was the Purple Seal Fish. The Purple Seal Fish is the size of a small carp. Its whole body is red and very cute. On both sides of its body, there is a purple "seal". The color of this seal is Pure purple, without any variegation, hence the name of the purple seal fish! Then, we saw the gentleman and cute penguins. The little penguins here were chasing each other and playing in the water. They swam around like fish, waving their two forelimbs like wings, and flying like birds. , the baby penguins were swimming happily in the water, as if they were showing us their beautiful swimming postures. The little penguins and I played through the glass, and imitated their appearance and ran around in front of the pool. The little penguins It seemed that it knew what I meant and swam faster, so that I couldn't catch up after chasing it for a long time. I think penguins are really the cutest animals in the world! Finally, we walked into a maze-like place, which was like a psychedelic underwater world. We were in close contact with the marine animals, separated only by a layer of glass, which gave me the feeling that I was also in the ocean with the animals. Let’s have fun together! I saw the charming fish around me "flying" in groups above my head. This is really a beautiful and dynamic ocean world. During this trip to the aquarium, I saw many marine animals and was very interested in them. They have more understanding... 4. A composition describing a turtle

There is a little turtle at home, which is a little smaller than my fist. Gray-brown hard back shell, semi-arched. The little turtle's head is triangular, probably to reduce water resistance. The small eyes are round and bright, quite energetic, and there are two small nostrils at the front of the head, which is very interesting. Look again, the four little legs are short and thick, covered with tiny scales, and have five small claws at the end. By the way, there is also that thin and long little tail, which is so fun to drag behind the back.

Normally, the little turtle lies quietly in the water, sticking its head out of the water, motionless, and looks "quiet". However, it will notice the slightest movement, even the sound of footsteps, and immediately retract its head, revealing only its two small eyes, looking alertly. After a while, it will shake its neck and test it bit by bit. The ground poked its head out. The little turtle is so vigilant!

I think you won’t believe that this slow-moving and seemingly clumsy little guy can catch fish! But this is wrong.

Once, I fed a few small crucian carps three or four centimeters long to a small turtle. It's really interesting. As soon as the little fish was put into the basin, its neck that had just been retracted stretched out again, and its two small eyes were staring at the little fish. I wondered curiously: Can it catch small fish? The little fish is so clever, but it... I didn't expect that the little turtle was smarter. It didn't act recklessly, but lay there calmly, waiting for the opportunity. A few small fish did not expect that their natural enemy was so close, and they were still swimming back and forth. I held my breath and opened my eyes wide. Finally, a small fish swam in front of the little turtle. The little turtle quickly caught up with it, opened its big mouth and bit the little fish's head. The little fish only shook its tail twice and stopped moving. The little turtle climbed a few more steps until he thought it was "safe" and then started to enjoy his meal with confidence. I saw it stretching its neck vigorously, apparently swallowing small fish, and its two front legs were still swinging back and forth, as if exerting force. Look, how interesting!

However, if you disturb it while it is eating, it will immediately put down the food and stick its head out of the water to "reconnaissance" before continuing to eat.

It can be seen that the little turtle refuses to let down his guard even when eating!

Anyone who knows a little bit of history knows about "Oracle Bone Inscriptions". In the Shang Dynasty, people dug holes in tortoise shells and then roasted them on the fire. When the holes exploded into "Bu" shaped patterns, , the diviner determines good or bad luck based on this, and then carves the prayer, the result, the date of the divination, and the diviner's name on an oracle bone, which becomes "oracle bone divination." Nowadays, people have obtained a lot of valuable information from the tortoise shells and animal bones unearthed from the Yin Ruins.

Not only that, the meat of the tortoise is also edible and the tortoise shell can be used as medicine.

It seems that the little turtle is not only smart and cute, but also an animal that is very beneficial to humans. 5. Write an essay about the ocean

Hello! Provide an article about the ocean that I have saved. It should be original and you can check it for your reference.

The ocean is the blue treasure house of human food. "Food is the first necessity of the people." Human beings must survive and develop. Food is the foundation and eternal subject of human survival and development. China, the giant of the East, holds its head high and uses sweat and wisdom to support a large family of 1.2 billion children. It accounts for 7% of the world's arable land and feeds 22% of the world's population.

However, with the increasing depletion of land resources, the continuous deterioration of the environment, and the rapid growth of population, the pressure for survival continues to increase. Where is the way out? China, when she raised her head from the loess soil, set her sights on the vast ocean and sounded the clarion call to march towards the ocean. The ocean, an important basis for human survival and development, is the largest resource treasure house, and marine life is one of the richest and most important marine resources in this blue treasure house.

Marine life has a wide variety and abundant resources. Coupled with the diversity of chemical components and the effectiveness of biological utilization, it has great potential to provide food, medicine and energy for mankind. According to statistics, about 500,000 species of animals live in oceans and coastal zones, accounting for 4/5 of the total number of animals on the earth. In addition, there are 13,500 species of plants growing in the ocean.

Scientific research shows that there are 2.6 trillion tons of biological resources in the world’s oceans, but the current development and utilization of marine life is still in its infancy, providing only 2% of human food. In the 21st century, the ocean will become the "second granary" of mankind, with a cultivated area approximately 15 times that of land. For example: As long as seaweed growing naturally in offshore waters is processed into human food, the annual output is equivalent to 15 times the current total world wheat output.

If algae and plankton are included in the food range, the ocean can support 30 billion people. Nowadays, when people mention marine food, they think of delicious fish, shrimp, crab, shellfish and other animals. In fact, the focus of what is called "marine food agriculture" is seaweed plants.

For example: One hectare of seaweed culture on water surface can extract 20 tons of protein after processing, which is equivalent to the protein content of soybeans produced in 40 hectares of cultivated land annually. What an attractive development prospect this is! The sea is not only the cradle of life, it also nurtures a wide variety of marine animals and plants. In the vast sea, there are gleaming noctilucent insects, jellyfish with crystal-clear bodies that drift with the current, beautiful corals, colorful shellfish, armored shrimps and crabs, and squid that can spit clouds of mist and various kinds of fish. There are many kinds of precious sea cucumbers, as well as all kinds of strange fish, ancient and tenacious sea turtles, graceful seals, sea lions, walruses and dolphins, as well as huge giant whales, etc., they all live together in this bustling planet. The family forms a world of bizarre marine animals.

Coral has left a good impression on people throughout the ages. Its branches are slender and flexible. After processing, it becomes a valuable decoration. In the past, people once regarded coral as a plant and called it "coral tree". ” This is because it is so much like a plant. Live corals die, and new corals regenerate. Over time, year after year, the calcareous skeletons of dead coral polyps form various barrier reefs. Many islands in my country's Xisha and Nansha Islands are like this. coral reef.

Marine fish, there are about 30,000 species of marine fish in the world, and there are 2,000 species in my country's waters. Fish are colorful, gorgeous, and strange, unmatched by any other marine life.

So, what is a real fish? The so-called real fish must meet three conditions: first, it is a vertebrate living in water all its life; second, it uses gills to breathe and fins to move; third, it has real upper and lower jaws. Although the cuttlefish, abalone and whale we call in our daily life all have the word "fish" in their names, they are not real fish.

Cuttlefish and abalone are molluscs among invertebrates, and whales are marine mammals that use lungs to breathe. Among marine fish, the most colorful and beautiful one is the butterfly fish, the fastest swimmer is the swordfish, which can swim up to 130 kilometers per hour, faster than a train, and the most vicious one is the shark... There are hundreds of these things Strange marine fish are extremely closely related to humans. They are an important source of protein for human consumption. They are not only delicacies on the table, but also raw materials for medicine and industry.

Leviathans are mammals that live in the ocean. As we all know, mammals are the most advanced animals in the biological world. From the perspective of evolutionary history, there were no mammals in the ocean. They later returned to the ocean from land.

It is still unclear when and what caused them to return to their hometown. The characteristics of this type of animal are viviparous, the young grow up on breast milk, breathe with lungs, have a constant body temperature, and have a developed nervous system.

There are more than 130 species of mammals in the ocean, such as whales, dolphins, dugongs, seals, sea lions, etc. At present, the largest blue whale caught is 33.5 meters long and weighs 1950 tons, which is equivalent to the weight of 35 elephants. It can eat one ton of krill in one meal and 4-5 tons of krill in a day.

Dugong, commonly known as "mermaid" or "manatee". People often say that it is the ugliest animal, and its appearance cannot be said to be "beautiful." However, people give it the nickname "Mermaid". This is probably the literati and poets who have never seen them in person, and they are interested in the legend. It's just a beautiful imagination added, so the originally ugly animals become "beautiful".

Although dugongs are ugly, they are very docile. As early as the 1960s, some people predicted the widespread military use of sea beasts, which could collect intelligence for the navy.

In recent years, research on marine animals in various countries around the world has advanced by leaps and bounds, with remarkable results. Seaweed is the main body of marine plants, with more than 20,000 species. Currently, there are about 100 species of seaweed that can be used as food.

There are microalgae that are almost invisible to the naked eye. Some of them are food for fish and shrimp, and some are microalgae food that can be developed and utilized. Microalgae are rich in nutrients and minerals such as protein, fat and sugar.

For example, the protein content of chlorella is as high as 88.2% and spirulina is as high as 71%. They are processed into food and are called "compressed biscuits". Large algae in the ocean, such as kelp, wakame, Ulva and nori, are popular marine vegetables that are rich in nutrients and brightly colored.

Macroalgae are the largest algae in the ocean, more than 300 meters long and can grow more than 60 centimeters per day. These large brown algae constitute the so-called "undersea forest" and become the "fertile grassland" of the ocean world. Not only that.

6. Write an essay about the ocean. Don’t write too maturely. About the benefits and disadvantages that the ocean has given us

It is already 2060. Because the population is increasing too fast, there are almost no people on land. A place where people can live. As a scientist, I have the responsibility to improve the living space of human beings. For ten years, I have been committed to research on expanding the living space of human beings. Today, I have finally achieved my wish. The future In the ocean, you can see the houses I designed everywhere. The outside of these houses is made of super alloy. In order to enjoy the colorful underwater world indoors, I used transparent super alloy. You don’t have to worry about whether there will be anything inside. Oxygen, the house is equipped with an oxygen converter, which can change seawater into oxygen; some people are also worried about tsunamis. You can rest assured when you live in a house like this, because the super alloy I use is the hardest material in the world. Nothing can be destroyed. You can also see many people riding on the back of the big fish and letting the big fish take them where they want to go. That's because people feed the fish the "Miracle No. 2" I invented. As long as That is a kind of medicine that I carefully invented that can be given to pets or animals. As long as you take this medicine, no matter how ferocious the animal is, it will be as docile as a little sheep. You can also keep small animals in the sea as pets. You You must be wondering, why doesn't this person have an oxygen tank on his back? No need to make a fuss. If you look carefully, you can definitely see that there is a transparent oxygen mask on the person's head. Where does the oxygen come from? I have to talk about the sandwich clothes I invented. There is a small oxygen converter in the sandwich, and an oxygen mask is connected to the back. When you put on this clothes, you will feel as comfortable as breathing air on land. In addition, the wrist There is a remote control installed on the boat. If you want to bask in the sun on the sea, just press the "float" button and you will immediately float on the sea to bask in the sun. If you want to swim, just press the "swim" button and you will be able to swim. Swimming like an athlete. This is the ocean I imagine in the future. I hope my dream can come true. 7. A 600-word essay about the aquarium

The future ocean

The ocean has become an underwater space, with extremely hard transparent glass pipes leading from the land to the bottom of the sea. It is convenient for people to go to the seabed along the glass pipe, and they can see many strange underwater animals and plants along the way. The glass pipe leads all the way to the underwater petting zoo. There are no monkeys, peacocks or other land animals here, only seahorses, sharks and other ocean animals. You can watch them and buy them back. There are undersea plants next door, and there are also marine plants in the botanical garden. You can buy some and keep them, but you have to use seawater to grow them.

There is a technology development station under the sea, where all high-tech problems can be easily solved. Because the ocean is very rich in minerals, treasures, and rare metals, people use them to develop many high-tech products. No, another potion has been invented. People can rub it on their bodies without having to wear a diving suit or go into the water through a glass pipe. How leisurely it is to take your own fish and walk freely in the ocean. If your pet is a shark or dolphin, you can sit on them and spin around a few times like a horse. Back on land, you can also let the fish walk on the street like puppies and kittens.

The ocean of the future will become a good place for people to live, and underwater cities will appear here. The house made of beautiful coral looks more like a work of art. Schools of fish are playing around you, making you feel like you have become one of them.

A composition describing a turtle

A little turtle

It is wearing a broken shell robe, shrinking its head and shrinking its head. It paddles on all fours in the water and crawls slowly on the shore. What do you think it is? who? Yes, it is a little turtle. It is a Brazilian turtle I bought at Qingdao Polar Ocean World on May 1st. His name is "Dadai". The reason why he is called "Dadai" is because he often looks at me blankly.

The little green turtle is so pretty. It has a dark green shell and a retractable oval soybean-like head with two orange oval patterns on its head. The little green turtle's eyes are on both sides of its head and are shiny. It's very small, smaller than a mung bean! There are "three nostrils" on the front of the head. There is a small spot between the two small nostrils, so it looks like there are three nostrils. There is a small and pointed mouth under the nostrils. The mouth is so small that you can't even see it unless you look carefully! It has four short legs that alternate left and right when crawling. There are also sharp nails that make a "pricking" sound when crawling! A small pointed tail swung back and forth under the turtle's shell. Turtles, like frogs, have a silly look under their necks when they breathe, which is very cute.

The little turtle is very vigilant and will shrink its head when it hears the slightest sound. Otherwise, why would it have the "good name" of "the turtle with its shrunken head"? Today, I just wanted to tease it for fun. When it was moving, I touched the turtle tank with my elbow without knowing it. Suddenly, I retracted my head into the shell. After a while, I slowly and slowly He stretched out his head and looked around, as if he was investigating, which was very cute.

Little turtles are more interesting when they eat. One day, I put the turtle food in a glass bowl, crawled to the place where the turtle food was, touched it with my little head, and then retracted my head. Then, it tried again several times before it wolfed down the food. Then he ate. It often missed the food and didn't get the food for the first time. It looked up at me frustratedly, as if to say: "Master, where is the food?" I just smiled and didn't answer, and it put its head into the water again and went to eat again.

At night, as long as it yawns, it will exercise before going to bed: crawling here and crawling there. When it gets tired, it will lie down next to the big stone in the water and start snoring. Huda fell asleep.

Little turtles are not only cute sometimes. Of course, there are also times when I am naughty. I remember one time, I wanted to test whether the little turtle was afraid of falling, so I fell down from a height of five meters. The little turtle fell to the ground, with its legs in the air. I thought, he It must have fallen badly, but after a while it flapping its four paws back and forth, and after a while it turned over. As a result, it ran away from left to right, and couldn't be caught. When it didn't catch it, it ran away again. He came out and stared at me, seeming to say: "Little master, come play with me for a while."

This is my lively and cute little turtle - Dumb. She's so cute! 9. Write a composition on how the little turtle entered the sea

On the edge of the blue sea, a little turtle crawled out of the hole, and an eagle hovered over the small sea ***. A tourist picks up a baby turtle and puts it into the sea. After the tourists left, a large group of baby turtles crawled out, and a group of eagles flew over. . . .

It turns out the first turtle was a Scout. That tourist had good intentions but did bad things. If tourists let the turtle choose to advance or retreat by itself, it may crawl back into the hole and tell its companions not to go out yet. It is very dangerous. Then, the turtles won't come out in droves, which will preserve more life. The kindness of tourists will make the turtles in the cave think that someone will hug them if they go out.

This incident reminds me of Chinese parents. Many parents always hold their children until they are 18 years old before throwing them into the sea of ??life.

In fact, the life of a baby sea turtle is not only threatened by eagles, but also by other animals in the sea. Excessive love is hurtful, it can only make those children being held vulnerable and incompetent in the cruel competition.

In the animal kingdom, how to educate children is worth learning from us humans. The lioness will throw the cub down the hillside and let the cub climb up on its own; the eagle will throw the eaglet off the cliff and let it fly by itself. The eaglet will either spread its wings and fly, or fall to death while the eaglet is struggling to spread its wings. Learned to fly.

I think that the little turtle must face and overcome the hardships it encounters by itself. If it cannot learn to survive independently, it will be eaten by its opponent sooner or later.

Parents who love their children infinitely should not give mobile phones to junior high school students, do not wash the dirty clothes that high school students bring back from school, and do not buy houses early for their children who go to college. The child in your arms will never grow up.

Let the little turtles go to the sea by themselves, and let the children learn to face the hardships of life. In the sea of ??life, only strong and independent people can become trendsetters! 10. Composition on Youshengya Ocean World

Youshengya Ocean World In mid-August, my parents and I went to Dalian together.

When we passed by Shengya Ocean World, I went to visit it with my mother. I originally wanted my dad to go, but he didn’t want to go because he thought there was nothing interesting inside, only some marine animals, and it was an optional attraction at his own expense.

My mother and I first visited the aquarium. There are all kinds of marine animals there, turtles and sharks.

There is also an attraction called the Shark House. Once you enter, you can see horror movies about sharks. The submarine soars through the ocean, only to have sharks arrive.

He banged his head against the window of the submarine, causing a big hole in the window. To the front, there is another box, which is shaking constantly, as if a shark is struggling inside.

There is a dummy next to him, lying on the bed sleeping, with a bulging belly and snoring sounds, as if he is breathing. We also saw the "Titanic". The above introduction said that it can sink more than four thousand meters. This is when I found that it was too small. After a closer look, it turned out to be simulation technology. Hey! What a bummer.

After passing the Shark Museum, we came to the Ocean Tunnel. My mother and I walked in the undersea tunnel as if we were really in the sea. It was very cool inside, but I discovered carefully that the air conditioner was actually on.

All kinds of fish were swimming above our heads, including sharks, rays and many other kinds of fish that I can’t name, as well as various marine animals such as turtles and corals. It was really It dazzled us. I quickly asked my mother to take some photos of me.

After passing the ocean tunnel, the staff said that a love story about a mermaid and a prince would be shown soon. Just when I was about to watch it, my mother suddenly said that he had lost his ticket and hurried back. After searching, it turned out that this drama was not well received either. After that, I and I also went to the Polar Museum.

There is a fat polar bear there. It is half lying in the water and is larger than I thought. There are also majestic Arctic wolves walking around inside. Their heads are bigger than mine.

There are also short and cute penguins. When they see us approaching, they quickly come over and look at us. It seemed like he wanted to take a photo with us.

I stick to the glass and can feel the coolness inside. There, my mother and I watched the walrus show together. The walrus and the trainer cooperated so well. The trainer threw the circle to it and it quickly caught it.

The fat walrus can actually perform such difficult movements. It can stand up and even do sit-ups, but it only did a few times and then stayed on the ground. The trainer touched it with its hands, and it used its "hands" to cover its face.

At this time, the animal trainer wanted to invite a woman to come up and said that he wanted to give her a surprise. A lot of hands went up.

The animal trainer chose the big sister closest to him. When she got there to give her a surprise, the animal trainer told the walrus to kiss her, and the big sister suddenly blushed.

At this time, the naughty walrus shook his hand, as if to say: "No." It resolved the embarrassment in his unique style, and everyone laughed, including the big sister. The animal trainer quickly invited her down.

There are a lot of fun things to do in Shengya Ocean World. If you are curious, you can visit it.
