A self-reported description of whales

I believe that you will often come into contact with composition, especially expository writing, which is of great significance in composition. The characteristic of expository writing is "saying", which has certain knowledge. How to write this type of composition? The following is my carefully compiled whale self-description, welcome to share.

Whale self-report description article 1 Have you seen the sea? This is a blue boundless ocean. This is a fish. Shrimp. Turtles are home to all kinds of marine life, and there are beautiful seaweeds on the seabed. Coral. I like this big family very much because I am also a member of this family. My name is Beibei, and I am a whale. Do you know me?

We are much bigger animals than elephants, with a maximum of160,000 kg and a minimum of 2,000 kg. Our tongues are heavy, as heavy as a dozen big fat pigs! It's not only heavy, but also big: four people are reading in our mouths around the table, which is very spacious.

Although we live in the ocean, we are not fish. Like you, we are mammals and grew up drinking milk. We are big, but our eyes are small and our tails are horizontal fins. We also breathe with our lungs, so we must breathe regularly. Our nostrils grow on our heads. We baleen whales have two nostrils, while toothed whales have only one. When we breathe, our nostrils will emit a "water column", just like a fountain in the garden. When our lungs are filled with air, we will dive into the water.

We sleep every day. When we sleep, we always like several heads to sleep together, with their heads inward and their tails outward, forming a circle and floating quietly on the sea, just like a huge swimming ring. Only in this way can we feel safe when we sleep.

In the whale family, we each have our own strengths. Let's talk about Moby Dick's uncle and aunt. Their voices are strange. There are hundreds! They can emit the roar of wild animals, the Cleisthenes of cattle, the snoring of pigs, the neighing of horses, the screams of birds, the screams of women, the groans of patients and the crying of babies ... Isn't it amazing?

How lovely and lively we are. Do you like us? We welcome your arrival!

The whale's self-report description 2 Hi! Hello, everyone, I am a famous tiger in the sea-killer whale. If you want to talk about me, some people may not understand. Let me introduce you!

My real name is killer whale, and killer whale is my scientific name. Mammals, Cetaceans, Dolphinidae. It is 6- 10 meter long and weighs 6-8 tons.

Many people regard us as fish and call us "whales", which is wrong. In ancient times, we whales lived on land with cattle and sheep. Then the environment changed, and it took us a long time to become fish.

We are also experts in camouflage, which brings us camouflage skills. If the fish swim past, they will think I am a big stone; If you swim from below, you will mistake it for a white cloud.

We are also snorkeling champions. Each whale can swim for about 20 minutes after breathing, and an adult killer whale can swim for about 30 minutes. When we are hungry, we often make an appointment with our friends, take a deep breath at the same time, and then dive into the deep sea to kill the big fish and drag them to the shallow sea. Then have a delicious meal with relish.

Speaking of eating, I'm hungry again. Stop it, goodbye!

Hello, everyone, I am a lovely blue whale, 29 years old this year. My name is Qiqi, and I am a very smart blue whale.

Our whale ancestors used to live on land, but later, because of the change of environment, they lived in shallow sea near land. After a long time, the forelimbs of ancestors gradually became fins, the hind limbs completely degenerated and the whole body became fish. In this way, our ancestors adapted to life in the ocean.

Guess what? We blue whales are the largest animals on the earth at present. A baleen whale with whiskers and no teeth in its mouth is called a baleen whale with two nostrils. In our blue whale family, the weight of an adult blue whale can grow to about 30 times that of an African male elephant, so we blue whales are the real marine behemoths. Our average length is about 26 meters and the highest record is 33 meters. 5 meters, average weight 150 tons. The tongue of a blue whale is more than 3 meters thick and weighs more than an elephant. The blue whale is also a unique' Hercules' in the animal kingdom. A blue whale traveling at a speed of 28km/h can generate a pulling force of1250kw.

Some people will ask,' Whales are really big. "What do they eat?" We blue whales are also called baleen whales. Baleen whales mainly eat shrimp and small fish. When we swim in the sea, we open our mouths and suck many small fish and shrimps into our mouths together with seawater. Whales are viviparous, and young whales grow up on the mother whale's milk. These characteristics also show that whales are not fish, but mammals.

Students, after listening to my introduction, do you know more about whales?

Hello, I'm a fat fin whale. My figure is very fat, and the fat is about 35-50 cm thick. But I don't know how thick it is, because I haven't measured it, and I can't measure it, because I have become a fish. I have to start with my ancestors: my ancestors lived on land like cattle and sheep. But later, due to the change of our living environment, our ancestors had to live in the shallow sea near the land. After a long time, we degenerated and our forelimbs and tails became fish. No wonder people call us whales.

Because we breathe with our lungs, we can't stay in the water for a long time. We have to breathe air on the water occasionally. When you exhale, the air in the hole above your head will take the water to the sky and form a column of water, which is very spectacular.

We are very big. Eight elephants haven't arrived yet. Although the whale trip is very heavy, our "boss" is very heavy, and a tongue can be as heavy as twenty big fat pigs. Awesome!

Our baleen whales are mainly eat small fish and shrimp. When swimming, we open our mouths, suck fish and shrimp into our mouths together with seawater, then discharge seawater from the channel and swallow the fish and shrimp. On the other hand, toothed whales eat big fish and marine animals, and sometimes they eat us. What a traitor.

This is our whale family! Whale exhibition

Whale is a kind of mammal living in water, which has the same physiological characteristics as terrestrial mammals, such as breathing with lungs, viviparous and so on, and has evolved some special physiological structures to adapt to the aquatic environment. Whales are divided into three categories, namely baleen whales and toothed whales. The grouping of these two whales mainly depends on their different ways of eating. The main morphological feature of baleen whales is that they have no teeth, but there are great baleen whales, which can be used to screen plankton. So it is filtered food. The main feature of Toothed Whale suborder is that it has teeth and is predatory, and the number and arrangement of teeth will be different from the direction of predation. There are about 79 species of 13 families in the world.

Although the whale has the word fish, it is actually not a fish, but a mammal. It has many characteristics very different from fish. For example, the average fish swings its tail fin left and right to move forward, while the whale swings its tail fin up and down. They use flippers at the front end to keep balance and control the direction of force. Some whales have fins at the top of their backs to keep their bodies upright!

Whales are social animals. They usually live in groups in the sea, but when whales breathe, they need to swim to the surface. At this time, the whale breathes through the blowhole on its head, and when it exhales, the water in the air will condense and form the familiar fountain shape. Experts can even tell the species of whales from the height, width and angle of water spray! There are many kinds of whales, which can be roughly divided into toothed whales and baleen whales.

Whales have a very thick layer of fat under their skin, which is also commonly known as whale oil. It can keep whales warm and store energy for a rainy day. Because whales have many special structures in their bodies, they can breathe in the water for a long time and slow down their heartbeat. Therefore, when it sinks to the bottom of the sea, it will take a long time to surface again. In addition to the oxygen storage structure, when a certain part of the body needs a lot of blood supply, there will be a special function of centralized supply in the body!

Hello, everyone, I'm a newly-born whale. We also have a Latin name "Sea Monster". This shows how afraid you humans are of us!

Tens of millions of years ago, our ancestors were on land. Due to the change of environment, we had to live in shallow sea. When we returned to the land, we found that we could not live without those delicious fish and shrimp, and we began to evolve into fish. Endlessly, we have to settle in the ocean, leave the plains of freedom and start a new life.

Although we whales are big, our eyes are surprisingly small and our eyesight is poor. If we are human, we should wear glasses of several hundred degrees. Did you know that we whales have no lacrimal glands in their eyes? In other words, no matter what you do to us or spicy our eyes with onion juice, it's useless. At least it can't make us cry for decades.

Our economic value is very high. For example, our fat can be used as oil and our bones can be used for scientific research. However, our meat is eaten as fish by some cruel people, making millions of delicious dishes and becoming Chinese food for millions of people. In ancient times, your tools were poor, so we could play carefree. As long as you humans dare to kill us, we will destroy your ship in an instant. But now, you have changed warships and used cannons. One shot and we're dead. Please don't kill us.

Oh, dear! Another compatriot was injured. I want to treat him. Goodbye.

I live in a vast ocean, and there are many marine life, one of which is very big, and that is me and my kind-whales.

I am a whale, that's right. But you must not ridicule me without seeing me: "It's definitely not as big and heavy as an elephant, and you may not have seen an elephant, haha!" ..... I can tell you that I am much bigger than an elephant! Our animals weigh hundreds of tons at most, and newborn whales are as heavy as elephants. At this time, people who have checked the information will say, "Ah, so you are so powerful!"

I belong to the baleen whale family Yes, it is the blue whale! Usually eat shrimp and small fish, but in the process of foraging, a bloody scene suddenly appeared. I was among the corals when I suddenly saw an adult baleen whale surrounded by dozens of killer whales. Fortunately, it was not found. I saw them kill the fin whale with sharp teeth, and the blood stained the sea area red. They were frantically grabbing at the food and biting it. I really snuck out when they were eating like cats and dogs. This adventure also taught me that there is a whale that eats animals like this.

Year after year, it has entered the nineteenth century, and the expectation for a better future has vanished. Today's human beings have killed all my flesh and blood compatriots, and there is almost no wind left. They took the life of marine life with bait and hook, and my heart was broken, but there was nothing I could do. I can only watch my relatives and friends get killed. I really can't figure it out: "Have I committed any heinous crimes and let others punish us?" Why? "

But slowly, human beings began to realize the importance of maintaining ecological balance, and the ocean changed from lively to cold and cheerless, and returned to lively. My surviving compatriots and I are willing to forgive human mistakes and live in harmony with human beings. Suddenly I feel that the ocean is more vibrant and the sky is bluer!

I am a whale, living happily in the vast ocean. ...

The whale's self-report description 7 Hi! Hello everyone! Nice to meet you! I am a whale, the biggest blue whale among whales. Let me introduce us to you!

We are the biggest creatures on the earth. My weight is 60,000 kg, and my brothers all exceed100,000 kg! Our young whale is more than ten meters long and weighs seven or eight thousand pounds!

For the record, we are not fish. If you want to respect us, please don't call us whales "fish". Sorry, we are not whales, and we don't know about whales. Another thing, we are mammals.

Our family is divided into many categories. Generally speaking, there are two kinds: baleen whales and toothed whales. Of course, we blue whales are baleen whales.

Our baleen whales have three meals a day, mainly shrimps from eat small fish. Because we have no teeth, we can only eat them raw. On the other hand, toothed whales have sharp teeth. They eat big fish and marine animals, even whales! I'd better stay away!

Our ancestors lived on land like cattle and sheep, but after thousands of years of evolution, we moved from land to repulse bay and lived in the sea after adapting to the underwater environment. We still breathe with our lungs. Every once in a while, we have to breathe on the sea. This is very important! I can also spray water columns!

We sleep every day, just like humans. We always sleep together in small groups. Our heads are together, our tails are outside, floating on the sea, and we can swim whenever we hear anything.

We are viviparous, and our life span is not short, usually several decades to one hundred years.

By the way, I should get some fresh air on the water. Goodbye! Talk to you later! Now you know us, right?

In the blue ocean, there are all kinds of whales, and I am one of them-the narwhal.

Whales are divided into "baleen whales" and "toothed whales", and I belong to "toothed whales".

My body is different from other whales, not fat, petite and lovely. As a little lady, I think I should keep in good shape. My total length is * * * three or four meters, which may be longer than the combined height of three kindergarten children. However, my overall length is longer than the combined height of three adults, because I have a unicorn nearly two meters! This greatly increased my overall length. So, I'm also called narwhal.

I eat big fish and marine animals, and I especially like cod. Although some toothed whales eat baleen whales or something like that, I don't like it. Well, I'm too kind.

However, despite my friendliness, no whale wants to play with me. Is it because my horns are terrible? I can't. My horn is so beautiful that I can't bear to take it off. ...

Speaking of corners, I should be serious. I am three years old this year, and my horn has not been honed too much, so it is not easy to be targeted by human beings. But my brother is sixteen years old now, and his horns are big and hard, shining soft silver in the ocean. This kind of horn is the most easily targeted and becomes an ornament in human homes. Although this sharp unicorn can help when necessary, it is a burden when human beings kill.

My grandfather and menstruation both suffered bad luck. Well, it seems that having a beautiful horn is not a good thing!

Having said that, I think everyone knows me! Actually, I'm not a carefree narwhal. I am always trapped by friendship. ...

So, would you like to be friends with me?

The whale's self-report explanation Article 9 Hello everyone! My name is whale. It is a much bigger animal than an elephant. At present, the known whale weighs 6.5438+0.6 million kilograms (⊙o⊙). The smallest also weighs two thousand kilograms. A whale weighing 2000 kilograms was found in China. 1 The tongue weighs as much as a dozen big fat pigs! If he opens his mouth, people can't touch its upper jaw when they raise their hands in his mouth, and four people around the table are reading in his mouth, which is still very spacious.

We live in the ocean. Many people call us whales because we are shaped like fish. Actually, we don't belong to fish. We breathe with our lungs like cattle and sheep. This also shows that we are mammals. Our nostrils grow on our heads, and when we exhale, they surface. The water column formed by the gas from our nostrils is like a fountain in the garden. When our lungs are filled with gas, we dive into the water We have to breathe once in a while. The water column of baleen whales is thin and high, while that of toothed whales is thick and short.

We were viviparous, and we grew up on our mother's milk. This also shows that we are not fish. Our life span is very long, usually from several decades to one hundred years, but our number is decreasing. Help us!

Whale self-report description article 10 Hello everyone, I am an extremely fierce "tiger in the sea"-killer whale. People also gave me a fierce and loud name, called killer whale. If I ask you who is the overlord in the sea, you may not hesitate to answer "shark". But you are wrong. The real overlord in the sea is me, and sharks are just a piece of cake in front of me.

Our killer whale is the smallest whale, with a body length of only 10 meter and a weight of 7-8 tons, but it is also a monster for you and me; I can swim 55 kilometers per hour, and I can swim twice as fast when chasing. No matter what animals are in the ocean, as long as I find them, they can't escape. Turtles, dolphins, sharks, walruses and even whales are my regular prey. Hey, hey, what's up? I'm fine! Not only that, but we are also smart. Let's see how to hunt.

When we meet a big whale, we will "organize", surround it first, and then two companions will rush up and bite its two flippers respectively, making it difficult for it to escape. Then other companions swarmed and chewed fiercely. After eating for a period of time, there will be companions to bite the fins instead of whales and let them enjoy the food. Minke whales, humpback whales, gray whales and even the biggest blue whales are often attacked by us and become things in their stomachs. Sometimes we find that the whale hunting boat is dragging a dead whale, and we will rush into the shell of the whale, eat the whale oil inside, and then walk away, regardless of the bombardment of the whale gun. Sometimes we float motionless on the sea, belly up, like zombies. Whenever groups of dolphins or sea lions swim on the sea for food, they often approach without knowing the truth. At this time, we will quickly turn over and catch them and eat them with lightning speed.

Haha, I won't tell you, or you will be scared to get down. Goodbye!

Whale Description 1 1 Hello, I am the largest animal in the world-whale.

I said that I am the largest animal in the world, and I have a good reason. At present, it is known that our largest partner weighs160,000 kg, and the smallest one is 2000 kg. In China, we also found a partner who weighed nearly 40,000 kilograms and was17m long.

You must be thinking: what are we going to eat when we are so long and so big? We eat different kinds of whales. Our whales are mainly divided into two categories: like my baleen whales, mainly eat small fish shrimps; If toothed whales eat big fish and marine animals. I'm telling you, we have different kinds and eat different things. When my baleen whale is hungry, I just need to open a big mouth like a small bungalow to bring the fish and shrimp into my mouth together with the seawater, and then filter the seawater out of the whisker board, and the rest of the fish and shrimp will be swallowed by me, and I can eat more than 2,000 kilograms at a meal. Toothed whales are quickly eaten by biting big fish and marine animals. Once they surrounded a partner of mine weighing more than 30 tons and ate him up in a few hours. You must be thinking again. Then how do we sleep? When sleeping, I made an appointment with several partners to find a safe place, with my head inward and my tail outward, forming a circle and swimming when I heard anything. I think you must be thinking again that everything we do is in the water. It must be fish.

Then you are wrong. First of all, we breathe with our lungs, so we have to float to the surface of the sea every once in a while to breathe, and we are viviparous and grew up eating our mother's milk. All these characteristics indicate that we are mammals.

We have lived on the earth for 50 thousand years and are successful species. But in recent years, we have been slaughtered by human beings. In the one hundred years of the 20th century alone, 360,000 people of my companions were slaughtered by human beings, and we are now on the verge of extinction. Therefore, I cry every day: "help us!" " "

Description of the whale 12 Although I look like a fish, everyone calls me a whale. In fact, I am not a fish, but a mammal. Our whales are generally divided into two types. One is called baleen whales. They are very gentle, so they are only eat small fish shrimps because they have no teeth. The other is called toothed whale. Compared with baleen whales, its teeth are very sharp. It eats big fish and marine animals, and never eats baleen whales. But I am a gentle baleen whale, not fierce at all. I only eat weak Pippi shrimp and naughty little fish.

My ancestors used to be mammals, living on land and breathing with their lungs like cattle and sheep. Although we live like fish now, we still breathe with our lungs instead of gills. Baleen whales must breathe regularly like humans. The water column formed by my breath is different from other toothed whales or killer whales. Every whale has a different water column, some vertical and some inclined. Some are thin and tall, others are thick and short, and they are different. Although the water column is useless, it is actually very useful. You can tell the species and size of whales by the water column they spit out.

Other whales and I need to sleep and rest like humans every day. When we sleep, we will find a safe place to surround ourselves with other fish and sleep head to head. I think whales are particularly vigilant, because if whales hear something when they sleep, they will immediately disperse. Whales are mammals, that is, viviparous. Young whales grow up on the mother's milk, which also proves that they are mammals.

Do you know anything about whales after reading these?

My name is killer whale, a kind of toothed whale and one of the fiercest marine animals. Therefore, people have given me many nicknames: evil whale, killer whale and so on.

My figure is very big, spindle-shaped, about 600- 1000 cm long and weighs about 5000-8000 kg. I am very strong and powerful. The body color is black and white, the back is mostly painted black, and the abdomen is mostly white. There is a spindle-shaped white spot behind each eye and a saddle-shaped gray spot behind the triangular dorsal fin.

We like to live in groups in waters from 0 to 13 degrees. Our prey is mainly marine animals. In my tribe, there is a killer whale hero who once ate 13 dolphins and 14 seals. Sometimes, I will use some "tricks" to hunt: first, I will lie on the water with my stomach up, like a dead body. When the prey comes near, I will suddenly turn over, open my mouth and swallow them.

I am a "master of language" among cetaceans, and I can make 62 different sounds. I sneeze intermittently when I hunt fish, just like pulling rusty iron doors and windows. When the fish heard the sound, they were shocked and stayed where they were, which became my delicious meal.

Although I am a fierce and greedy beast in the sea, I seldom hurt human beings and am a "good friend" of human beings. I was domesticated by human beings in the aquarium and performed various wonderful programs. I am now a member of the animal unit of the U.S. Navy Underwater Operations Center, performing underwater diving, navigation, demining and other work.

Oh, by the way, I forgot to tell you that I am a mammal, and I was raised by my mother's milk. Don't call me whale in the future.

I am a whale living in the ocean.

I have a happy life with my brothers and sisters every day, but today I was caught by a group of marine experts while sleeping. I'm trapped in a huge science lab.

They first used a micro detector to see what kind of whale I was. I heard them say I was a toothed whale.

Then I opened my mouth with a steel rope. A man in a diving suit swam to my mouth, stood on tiptoe with my tongue and reached out his hands, but he still couldn't touch my palate. Injected me with anesthetic again, which made me fall asleep. When I woke up, I felt very uncomfortable and painful in my mouth. I looked at the glass and lost my tongue! This surprised me. I saw that damned expert weighing the ratio of my tongue to several big fat pigs. It turned out that I was treated as an experiment by them, and I couldn't help crying, thinking, "I am old in the world and young in the bottom", which is really pitiful.

Hey-I really miss ocean life!

Hello, I'm a whale. Many people may know us, but they don't know us very well. I will introduce us to you today.

There is only one word at the beginning of our name, and that is whale. Many people call us whales, which is wrong. Actually, I don't belong to fish. I grew up on land a long time ago. For various reasons, our forelimbs and tails gradually become fins, and the rear position is completely degraded, adapting to life in the ocean.

People who are familiar with us should know that our bodies are very big, and a tongue is as heavy as dozens of big fat pigs. Four people are reading in my mouth around the table, which is still very spacious.

Our species can be divided into two categories, fin whales and killer whales. We need to give priority to eat small fish shrimp, and we can eat more than 2,000 Jin of small fish in one meal. And our brother killer whales mainly eat marine animals, because we are not fish, which makes us suitable for lung breathing. Every once in a while, we have to pay the price in the sea, spraying water columns from our nostrils. Don't underestimate our water column. If human beings are sprayed by our water column, they will be born. The water column of our baleen whale is vertical, thin and high, while the water column of killer whale is inclined and short.

The way we sleep is also unique. We always stick our tails out in a circle. When we heard the noise, we left immediately.

We grew up mainly by eating the milk of the mother whale. When we were born, we were more than ten meters long. Little whales can grow 50 to 30 kilograms a day. Our life span is similar to that of human beings. Generally, we can live to 50 to 100 years old. All right, that's it.

Good human, I hope you can protect us from extinction and make us friends.
