Write a composition about sea turtles.

1. Look at the picture and write about the turtle in the sea Once upon a time, there was a turtle whose wish was to live in the sea.

One day, he saw a Chinese sturgeon swimming 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 tortoise said, "I really want to see it." Sturgeon said, "As long as you follow the Yangtze River, you will reach the sea."

The tortoise said, "Thank you. Bye. " The tortoise crawled slowly for five days and nights, and finally reached the seaside.

"ah! My god, this sea is so big! " The tortoise was very excited and rushed to the sea. The tortoise is swimming in the sea. He met a red lobster and a swordfish. Their mouths were like a blue-purple sword. He is a swimming champion.

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

There are all kinds of plants in the ocean, such as sea flowers, seaweed and corals, which are various, grotesque and beautiful! The tortoise forgot to go home. He likes everything in the ocean. He gradually stopped walking and his feet became webbed. Since then, there have been turtles in the world.

2. As soon as I entered the underwater world, I saw many grotesque corals, some like dragon horns, some like roses ... all kinds of small fish swam around among the corals. When I entered the hall, I saw a large group of tourists in a big circle. I was curious and walked over. It turned out that people were watching the performance. The wedding of the mermaid and the prince is being held in the underwater world. The prince rode chinemys reevesii, who was over 300 years old, to meet the bride, Miss Mermaid. They swam around in the sea, and the mermaid kept waving to the tourists. The tourists all laughed and got on the big shark sedan chair.

Out of the hall, I went to the underwater animal park, where there were many strange-looking fish, such as tiger grouper, angelfish, hairtail as long as a rope, and Yao fish like an umbrella ... They all had beautiful colors, such as yellow, black, blue and red. They are really beautiful and beautiful. Among these fish, I like sharks, swordfish and swordfish best. This shark is as big as a door panel. It opens its mouth, showing its sharp teeth, and opens its eyes like two big lanterns. Swordfish has a big and sharp sword on its tail. A whale is as big as a car, and its mouth is like a cave. A few stupid fish swam into his mouth unconsciously and became a delicious meal for whales.

The underwater world is really wonderful. Let me linger. I like underwater world very much

Writing a composition about turtles in Shanghai Aquarium This summer vacation, my parents and I traveled to Shanghai. Shanghai is a metropolis in China, with high-rise buildings everywhere. The Oriental Pearl Tower opened my eyes. Next to the Oriental Pearl Tower is the Shanghai Aquarium. From a distance, I saw a magnificent and beautiful building, just like a three-dimensional triangle on the ground. That's Shanghai Ocean Aquarium. Shanghai Ocean Aquarium is one of the largest marine aquariums in Asia, with the longest underwater sightseeing tunnel155m in the world. When we walked into the lobby 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. For example, purple Indian fish, lion fish ... each fish has its own characteristics, and each fish attracts our attention, so that we all stop to watch and forget to move on. All kinds of fish, big and small, red and green, yellow and blue, are colorful, and some even have several colors on their bodies, all for tourists to see. The first thing I saw was the purple Indian fish. The purple print fish is the size of a small carp. It's all red and very cute. On both sides of its body, there is a purple "seal" This printed color is pure purple, and there is no noise, so the purple printed fish is named! Then, we saw the gentle and lovely penguin. The little penguins here chase and play in the water. They swim around like fish, flap their wings like two forelimbs and spread their wings like birds. Little penguins swim freely in the water, as if to show us their beautiful swimming style. I played with the little penguins through the glass and ran around the pool like them. Little penguin seems to know what I mean. Finally, we walked into a labyrinth, which is like a psychedelic underwater world. We are in close contact with marine animals, only separated by a layer of glass, which gives me the feeling of playing with them in the ocean! I saw charming fish floating overhead in droves. This is really a beautiful and vibrant marine world. During this trip to the aquarium, I saw many marine animals and learned more about them.

4. The composition describing the tortoise My family has a little turtle, which is a little smaller than my fist. The beige hard shell is semi-arched. The little turtle's head is triangular, probably to reduce the resistance of water. Those small eyes are round and bright, very energetic, and there are two small nostrils at the front of the head, which is very interesting. Look again, the four calves are short and thick, covered with tiny scales and with five small claws at the end. By the way, there's that long, thin tail, dragging it behind. This is very interesting.

Usually, the little turtle lies quietly in the water, sticks its head out of the water, and looks very "quiet". But the slightest movement, even footsteps, it will find, and immediately retract its head, revealing only two small eyes and a face of alert. For a long time, it will shake its neck and try to stick its head out bit by bit. The little turtle is really vigilant

I don't think you will believe that this slow-moving and clumsy little guy can catch fish! But this is wrong.

Once, I fed a small turtle a few small crucian carp three or four centimeters long. Very funny, as soon as the little fish was put into the basin, its neck, which had just been retracted, came out again, and two small eyes stared at the little fish. I wonder: can it catch small fish? This little fish is very clever, but it ... didn't expect the little turtle to be smarter. It didn't make a move, just lay there quietly, waiting for the opportunity. A few small fish didn't expect that their natural enemies were close at hand and they were still playing in the shuttle. I held my breath and opened my eyes. Finally, a small fish swam to the little turtle. The little turtle cleverly caught up with it in a few steps, opened its mouth and bit the head of the little fish. The little fish only wagged its tail twice and stopped. The little turtle climbed several more steps until it thought it was "safe" before enjoying its delicious meal with confidence. I saw its neck stretched out hard, 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 eating, it will immediately put down the food, put its head out of the water to "spy" it, and then continue its delicious meal. It can be seen that even when eating, the little turtle refused to relax his vigilance!

Anyone who knows a little about history knows "Oracle Bone Inscriptions". In Shang dynasty, people once dug holes in tortoise shells and then burned them on fire. When these holes burst into "Bu"-shaped lines, the fortune teller decided the good or bad luck, and then carved the prayer, result and divination date on an Oracle bone, which became "Oracle Bone Inscriptions". Nowadays, people have obtained a lot of valuable information from tortoise shells and animal bones unearthed in Yin ruins.

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

It seems that the little turtle is not only smart and lovely, but also an animal that is very beneficial to human beings.

5. Write a composition about the ocean. Hello! Providing an article about the ocean I saved should be original. You can check it for your reference.

The ocean is the blue treasure house of human food, and food is the foundation and eternal theme of human survival and development. China, the oriental giant, held his head high and supported a big family of 65.438+0.2 billion children with sweat and wisdom, accounting for 7% of the world's cultivated land and feeding 22% of the world's population.

However, with the exhaustion of land resources, the deterioration of environment and the rapid growth of population, the pressure of survival is increasing. Where is the way out? China, when she looked up from the yellow land, turned her eyes to the vast ocean and blew the horn of marching into the ocean. The ocean is an important support for human survival and development, and it is the largest treasure house of resources. Marine life is one of the richest and most important marine resources in this blue treasure house.

There are many kinds of marine life, large resources, diverse chemical components and effective biological utilization, which have great potential to provide food, medicine and energy for human beings. According to statistics, there are about 500,000 species of animals living in the ocean and coastal zone, accounting for 4/5 of the total number of animals on earth. In addition, there are 1.35 million kinds 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 development and utilization of marine life is still in the primary stage, providing only 2% of human food. It is predicted that the ocean will become the "second granary" of human beings in 2 1 century, and the arable land area is about 15 times that of land. For example, as long as the seaweed naturally growing in the offshore waters is processed into human food, the annual output is equivalent to 15 times of the current world wheat output.

If algae and plankton are included in the food range, the ocean can feed 30 billion people. Now when it comes to marine food, people will think of delicious fish, shrimp, crabs, shellfish and other animals. In fact, the focus of "marine food agriculture" is seaweed plants.

For example, one hectare of aquatic algae can extract 20 tons of protein after processing, which is equivalent to the protein content of soybeans in 40 hectares of cultivated land for one year. What an attractive development prospect! The ocean is not only the cradle of life, but also feeds a wide variety of marine animals and plants. In the vast sea, there are sparkling night insects, jellyfish with crystal clear bodies, beautiful corals, colorful shellfish, armored shrimps and crabs, puffed squid and various precious sea cucumbers, as well as grotesque fish, ancient and tenacious turtles and graceful seals, sea lions, walruses and dolphins, and huge whales.

Coral has left a good impression on people of all ages. Its branches are slender and flexible, and it is a valuable ornament after processing. In the past, people used to regard coral as a kind of plant and called it "coral tree" because it was too much like a plant. Living corals die and new corals are born again. Over the years, the calcareous bones of dead corals have formed various barrier reefs. Many islands in Xisha and Nansha Islands in China are such coral reefs.

Marine fish, there are about 30,000 species of marine fish in the world, and there are 2,000 species in China waters. Fish are colorful, colorful and strange, which is beyond the reach of any other marine life.

So, what is a real fish? The so-called true fish must meet three conditions: first, vertebrates who live in water all their lives; The second is to breathe with the gills and exercise with the fins; Third, there are real maxilla and maxilla. The cuttlefish, abalone and whale mentioned in our daily life are not real fish although they all have the word "fish" in their names.

Squid and abalone are mollusks among invertebrates, while whales are marine mammals that breathe with their lungs. Among the marine fish, the butterfly fish is the most vivid and beautiful, and the swordfish is the fastest. The swimming speed can reach 130 km per hour, which is faster than the train. The fiercest fish are sharks ... these strange marine fish have a very close relationship with humans. They are an important source of human intake of protein. protein is not only delicious on the table, but also a raw material for medicine and industry.

Marine animals are mammals that live in the sea. As we all know, mammals are the tallest animals in the biological world. From the evolutionary history, there were no mammals in the ocean, but later they returned to the ocean from land.

It is not clear when and why they will return to their hometown. The characteristics of this kind of animals are viviparous, young ones grow up on breast milk, breathe with lungs, have constant body temperature and developed nervous system.

There are 130 kinds of mammals in the ocean, such as whales, dolphins, dugong, seals and sea lions. At present, the largest blue whale caught by people 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 one day.

Dugong, commonly known as "mermaid" or "manatee". People often say that it is the ugliest animal, and its appearance is far from "beauty". But people gave it the nickname "Mermaid", which was probably just a beautiful imagination added to the legend by scholars who had never met before, so the ugly animal became a "beauty".

Dugong is ugly, but very docile. As early as the 1960s, it was predicted that marine animals would be widely used in the military and could collect intelligence for the navy.

In recent years, countries around the world have made great progress in the study of marine animals and achieved remarkable results. Seaweed is the main body of marine plants, with about 20 thousand species. At present, there are about 65,438+000 kinds of algae that can be used as food.

There are microscopic algae that are almost invisible to the naked eye. Some are bait for fish and shrimp, and some are microalgae food for development and utilization. Microalgae are rich in protein, fat, sugar and other nutrients and minerals.

For example, the protein content of Chlorella is as high as 88.2%, and the protein content of Spirulina is as high as 7 1%. Marine macroalgae such as kelp, Undaria pinnatifida, Ulva and laver are popular marine vegetables with rich nutrition and bright colors.

Giant algae is the largest algae in the ocean, which is more than 300 meters long and can grow more than 60 centimeters every day. These large brown algae constitute the so-called "underwater forest" and become the "fertile grassland" of the marine world, which is not only.

6. Write a composition about the ocean. Don't be too mature. It's already 2060. About the advantages and disadvantages of the ocean. Because of the rapid population growth, there are few people living on the land. As a scientist, I have the responsibility to improve our living space. For ten years, I have been devoted to the research work of expanding human living space. Today, I finally got what I wanted. In the future ocean, you can see the house I designed everywhere. The exterior of these houses is made of super alloys. In order to enjoy the colorful underwater world indoors, I used the transparent super alloys. You don't have to worry about whether there will be oxygen in it. The house is equipped with an oxygen converter, which can change seawater into oxygen. Some people will worry about the tsunami. You can rest assured that living in such a house, because the super alloys I use is the hardest substance in the world, and nothing can destroy it. You can also see many people riding on the back of the big fish and let the big fish take them where they want to go. That's because people give fish "Miracle II" invented by me, as long as it is a medicine I carefully invented for pets or animals, as long as I take this medicine. No matter how fierce animals are, they will be as gentle as lambs, and they can keep small animals in the sea as pets. You must want to know why this man doesn't have an oxygen bottle. There is no need to make a fuss. If you look closely at people, you can definitely see a transparent oxygen mask on their heads. Where does the oxygen come from? I have to say this dress goes with a sandwich. There is a small oxygen converter in the mezzanine, and an oxygen hood is attached to the back. Wearing this dress will be as comfortable as breathing air on land. In addition, there is a remote control on the wrist. If you want to sunbathe on the sea, you can press the "float" button and immediately float on the sea to sunbathe. If you want to swim, you can press the "swim" button.

7. A 600-word composition about the aquarium: the future ocean.

The ocean has become an underwater space, and extremely hard transparent glass tubes extend from the land to the bottom of the sea. It is convenient for people to go down to the seabed along the glass pipe, and many strange underwater animals and plants can be seen along the way. The glass tube leads all the way to the underwater pet park. There are no monkeys and peacocks here, only seahorses, sharks and animals in the sea. You can look at it or buy it back. Next door is marine benthos, and the botanical garden is also full of marine plants. You can buy some and raise them, but plant them in seawater.

There is a science and technology development station under the sea, where all high-tech problems are solved. Because the ocean is rich in minerals, treasures and rare metals, people use them to develop many high-tech products. No, a potion was invented. People can rub it on their bodies and enter the water without wearing diving suits and passing through glass tubes. How leisurely it is to walk freely in the ocean with your own fish. If your pet is a shark or dolphin, you can sit on it and circle like a horse. Back on land, you can also let the fish walk in the street like dogs and kittens.

The future ocean has become a good place for people to live, and many underwater cities have appeared here. The house built by beautiful coral looks more like a work of art, and groups of fish play around you, making you feel like one of them.

Yes, the present underwater world is so beautiful and colorful, and the future underwater world will be more developed and gorgeous!

Ah, the underwater world is really beautiful now. There are so many quiet nights and stars. I sat on the golden beach with my chin in my hand, and I couldn't help thinking of the boundless sea.

In the future ocean, there are many colorful stars twinkling. This star is the size of a fist and can emit a series of lights. People who live here can use it as an electric light, which is both beautiful and energy-saving.

8. Composition describing tortoise Little tortoise

It was dressed in a tattered robe, with its head and brain shrinking. It paddles in the water and crawls slowly on the shore. Guess who it is? Yes, it's a little turtle. I bought the Brazilian tortoise in Qingdao Polar Ocean World in May 1. His name is "Dai". He is called "gawk" because he often looks at me gawk.

This little green turtle is very beautiful. It has a dark green shell and a retractable oval soybean-like head with two orange oval patterns on it. The little green turtle's eyes sparkle on both sides of its head. Very small, smaller than mung beans! There are "three nostrils" in front of the head, and there is a small point between the two small nostrils, so it looks like there are three nostrils. There is a small, pointed mouth under the nostril, a small mouth, which can't be seen without looking carefully! Four short legs, alternating left and right when crawling. There are also pointed nails, which are "stinging" when climbing! A small, pointed tail dangles under the turtle shell. Turtles, like frogs, are very cute when they breathe stupidly under their necks.

The little turtle is very alert and will shrink his head when he hears any movement. Otherwise, how could he have the reputation of "shrinking turtle"? Today, I just want to play with it. When it was moving, I touched the tortoise jar with my elbow unnoticed, and then I retracted my head into the shell. After a while, I slowly put my head out and looked around as if I were investigating. It's very cute.

Little turtles are more interesting when they eat. One day, I put the turtle food in a glass bowl, climbed to the place where there was turtle food, touched it with my little head, and shrank my head back. Then, it tried several times and wolfed it down. It often flies in the air and doesn't eat food for the first time. It looked up at me in frustration, as if to say, "Master, where's the food?" I just smiled and didn't answer. He dipped his head into the water again to eat.

At night, as long as it yawns, it will exercise before going to bed: crawling everywhere, tired of climbing, lying next to a big stone in the water and starting to sleep.

Little turtles not only have lovely moments. Of course, I am naughty sometimes. I remember once, I wanted to see if the little turtle was afraid of falling, so I fell from a place five meters high. The little turtle fell to the ground, and it landed on all fours. I think he must have fallen badly, but after a while, he swung his four claws back and forth, and after a while, he turned over. As a result, it fled left and jumped right, but it could not be caught. I didn't catch it when I didn't catch it

This is my lively and lovely little turtle-dull. Isn't she cute?

9. How did the little turtle get into the sea? Write a composition about the blue sea. A little turtle crawled out of the hole and an eagle circled in the small sea. A tourist picked up a baby turtle and put it into the sea. After the tourists left, a large group of small turtles climbed out and a group of eagles flew by. . . .

It turned out that the first turtle was a scout. That tourist is doing bad things with good intentions. If tourists let the tortoise choose to advance and retreat, maybe it will climb back into the hole and tell its companions not to go out for the time being, which is very dangerous. Then, turtles will not come out in droves, which will save more lives. The kindness of tourists will make the tortoise in the cave think that he will be hugged as long as he goes out.

This incident reminds me of my parents in China. Many parents always hold their children in their arms until 18 years old before throwing them into the sea of life. In fact, the life of the baby turtle is threatened not only by the eagle, but also by other animals in the sea. Excessive love is harm, which can only make those children who are held look weak in the cruel competition.

In the animal kingdom, how to educate children is worth learning. The lioness will throw the cubs down the hillside and let them climb up by themselves; The eagle will throw the baby eagle off the cliff and let it fly by itself. Eagles either spread their wings or die. Eagles learn to fly by struggling to spread their wings.

I feel that the hardships encountered by the little turtle must be faced and overcome by themselves. If it can't learn to live independently, it will be eaten by its opponent sooner or later.

Parents who love their children infinitely, don't give junior high school students mobile phones, don't wash dirty clothes brought back from school by senior high school students, and don't buy houses for children in college in the morning. The child in your arms will never grow up.

Let the little turtle go into the sea by himself and let the children learn to face the hardships of life. In the ocean of life, only strong and independent people can become trend-setters!

10. Visiting Shengya Ocean World Composition Visiting Shengya Ocean World In mid-August, I went to Dalian with my parents.

I went to visit with my mother when I passed by Shengya Sea World. I want my father to go, but he doesn't want to go, because he thinks there is nothing interesting in it, only some marine animals, and it is a scenic spot at his own expense.

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

There is also a scenic spot called Shark Hall. Once inside, you can see horror movies about sharks. The submarine soared in the sea, and as a result, the shark came.

He banged his head against the window of the submarine, and the window was immediately knocked out of a big hole. There is a box in front, which has been shaking, as if there were sharks struggling in it.

There is also a dummy next to him, sleeping on the bed, with a belly up and snoring, as if breathing. We also watched Titanic, which is said to sink more than 4000 meters. This is because I found it too small. On closer inspection, it turns out to be simulation technology. Hey! What a bummer.

After the shark house, we came to the cross-harbour tunnel. My mother and I walked in the cross-harbour tunnel as if we were really in the sea. It's cool inside, but when I checked it carefully, there was air conditioning.

All kinds of fish are swimming around above our heads. I can't name sharks, rays and other marine animals, such as turtles and corals, which really dazzle us. I quickly asked my mother to take some photos for me.

After crossing the cross-harbour tunnel, the staff said that a love story between a mermaid and a prince was about to be released. Just as I was about to read it, my mother suddenly said that he had lost his ticket and ran back to look for it. The play didn't look good either. Afterwards, I went to polar museum with you.

There is a fat polar bear there. It's half lying in the water, and it's much bigger than I thought. And the majestic Arctic Wolf. They have been walking around it, and their heads are bigger than mine.

And cute little penguins. When they saw us approaching, they quickly came to look at us. It's like taking a picture with us

I can feel the coolness of the room by sticking it on the glass. There, my mother and I watched the walrus show together. The walrus and the animal trainer cooperated very well. The animal trainer threw the ring to it and it quickly caught it.

The fat walrus can make such a difficult move. Can stand up and even do sit-ups, only to see it do a few movements and then lie still on the ground, the animal trainer touched it with his hand, and it also blocked his face with his "hand".

At this time, the animal trainer will invite a woman to come up and say that she will be surprised. Many people raised their hands.

The trainer chose an elder sister who was closest to him. When she climbed to the top to make a surprise, the trainer told the walrus to kiss her, and the big sister blushed at once.

At this time, the naughty walrus shook his hand, as if to say "no". It solved the embarrassment with its own unique style. Everyone laughed, and the big sister smiled. The animal trainer quickly invited her down.

There are many interesting things in Shengya Sea World. You can go and have a look if you are curious.
