The whale's self-reported composition is 500 words.

In daily study, work and life, everyone has written a composition, which is a verbal activity for people to express their feelings in written form. I believe many friends are very upset about writing a composition. The following is a 500-word whale self-report composition I collected for you. Welcome to reading. I hope you will like it.

The whale's self-report composition is 500 words 1 hi! Hello everyone! My name is blue whale! Like baleen whales, humpback whales and gray whales, they all belong to baleen whales! Nice to meet you! I also hope you can get to know me and my family and become good friends with us!

My family and I are mammals living in the ocean. We have 80 different species, mainly baleen whales and toothed whales, and we eat different foods.

I am a baleen whale family. So named, because we are born with tough horny things that are densely arranged like comb teeth. We filter the food in the water through our beards. In winter, we breed in the warm ocean near the equator, and in summer, we go to the cold polar sea to feed. Imagine the composition of the blue whale. In the very short summer, our consumption accounts for 9/ 10 of the whole year. Because we generally don't eat when we migrate, and we live by consuming body fat.

Toothed whales are our distant relatives, and they are named after having 240 teeth in their mouths. The function of their teeth is different from that of terrestrial mammals, and they are mainly used to catch food rather than chew it. They are smaller than our baleen whales, and some of them are cruel and often attack their own kind. They like to live in groups, so they are also called whales. They often "talk" to each other with whistles and ticks. Sperm whales, killer whales and dolphins are the most representative of their families. And my favorite is dolphin, because its "singing" and "dancing" are particularly beautiful!

Whether we are a baleen whale family or a toothed whale family, our bodies are very beautiful. Although we are big, we can swim as fast as we can move. We swim around in the vast sea every day, singing loudly about our happiness! Do you like us?

I am a little blue whale. I live in a beautiful ocean. I have a big happy family, a naughty brother, a gentle mother, a strong father and kind grandparents. However, our happy family has been shrouded in a layer of sadness recently.

The other day, you humans said I met a ship. That ship is so big! I thought it was fun, so I propped it up, and I was pulled by the bottom of the boat. I feel like crying in pain these days! You guys are so bad!

My brother went swimming in a new sea area for fun yesterday and got sick when he came back. To this end, mom and dad struggled for two days, and my brother's illness was discovered. It turns out that the water in that new sea area is not clean, and there are many pigments that you humans have not used up! You made my brother sick! You guys are so bad!

My grandmother is too old, and you human children still bully my grandmother! Last time grandma surfaced for fresh air, you threw a stone into grandma's nose, which made grandma have a hard time spraying it out! You guys are so bad!

You are so bad! You make me, my brother and my grandmother miserable! You are really, really bad! Our whales have poor reproductive ability, and it takes an average of two years to give birth to a calf. Due to your hunting and the pollution of the marine environment, the number of whales has decreased dramatically. For example, our lovely blue whale family killed nearly 360,000 in the 20th century, and now there are less than 50. Many whale species that have lived on the earth for more than 50 million years are endangered. Our blue whale family has long since changed from a big family to a small family!

How bitter our life is! The world is so beautiful, but you humans are so grumpy! Not good! Not good!

I am a whale, living in the vast sea, swimming freely in the sea every day, very happy.

I am about fifteen meters long and weigh about thirty thousand kilograms. But it is dozens of times the weight! Otherwise, I'm not the biggest and heaviest animal.

I tell you, although I live in the sea, many people call me a whale. Actually, I'm not a fish, but a mammal. In ancient times, my ancestors lived on land like the ancestors of cattle and sheep. Later, due to the change of environment, my ancestors lived in the shallow sea near the land. After a long time, the forelimbs and tails of ancestors gradually became fins, the hind limbs completely degenerated, and the whole body became fish-like to adapt to marine life.

My life span is very long, maybe decades or even hundreds of years. There are many members in our family, including the killer whale, the bluest whale on earth, and Moby Dick, a ventriloquist.

I like eating light rain and shrimp best. When eating, you even suck small fish and shrimp into your mouth with a lot of seawater, then close your mouth and filter the seawater out of the middle of the whisker and swallow it into your stomach. The mere mention of them makes my mouth water!

When I sleep, I always get together with several heads of the same kind. They usually find a safer place, with their heads inward and their tails outward, forming a circle and floating quietly on the water. If we hear any noise, we will immediately swim around and spread out.

Although I am very happy, I also have some troubles. Our reproductive capacity is very weak, and the number of members is gradually decreasing. Please don't kill us in the future.

Whale's self-report composition 500 words 4 Why am I called killer whale? The problem lies in the word "tiger". Everyone knows that I have a very famous title-the tiger in the sea! As soon as some big fish and marine animals saw us, they swam to one side in fear, and the small fish and shrimp froze on the spot. Haha, more importantly, we are still very United. Normally, once we find food, we will go out and eat together. If you meet a beast stronger than yourself, fight the enemy together. Oh! That's the old saying: "Share weal and woe."

However, because of our huge size and precious skin, humans kill us specifically, either to eat or to sell. My compatriot blue whale is an example. Due to a large number of human hunting and the pollution of the marine environment, its population has decreased sharply. In the 20th century, there were nearly 600,000 blue whales killed by humans, and now there are only less than 50.

There are also many "celebrities" in our whale species: Moby Dick is an expert in ventriloquism, and he can make more than 100 kinds of animal and human calls. There are the roar of wild animals, the cries of babies, the screams of women and so on. Our killer whale is more famous. A scientist found 13 dolphins, 14 seals and 60 trench cubs in the stomach of one of my companions. Haha, good appetite!

It's really amazing that we whales have so many characteristics and skills! If you humans sometimes complain that we attack you, it is because you interfere with our normal life. Because we have the same right to live, we also have the right to live on this planet! If you humans don't want this 5000-year-old animal to disappear in 2 1 century, then we appeal to humans: it is everyone's responsibility to protect us and animals!

Whale's self-report composition 500 words 5 Hello everyone! I am a famous world-famous whale. Hey, children, don't think our whale is a fish. If you think so, it's all wet. We whales belong to mammals. In addition, I want to give a suggestion to those children who think we are fish: it's time to supplement the' nutrition' of biology, hee hee!

Our whale is a huge animal. Just a small tongue is as heavy as a dozen big fat pigs. You are not as heavy as a big fat pig! If we open our mouths and you stand inside, your hands won't touch my palate. Four people around a table still look spacious. Look how old we are! Don't tell our ancestors, if they know, they will scold us.

Our family members are not small! Little brother-baleen whale, it has no sharp teeth, so it is mainly eat small fish and shrimp; Our third brother toothed whale, with extremely sharp teeth, specializes in eating big fish and marine animals, and sometimes devours our younger brother baleen whales. What a traitor! Our second brother, the blue whale, is 33 meters long and weighs 190 tons. A tongue weighs 4 tons, enough to fill a big truck. If it opens its mouth, it will be enough for ten people to go in and out. Our eldest brother, the killer whale, is the overlord of the ocean. If you don't make it angry, it will show its arrogance, just like "the tiger is not arrogant, and the monkey is called the overlord."

We whales breathe with our lungs. Every once in a while, we will surface and the exhaled air will become a column of water. Different whales have different water columns. The water column sprayed by the third brother is inclined, and the water column sprayed by the younger brother is vertical, just falling on himself. Give yourself a cold bath.

When we sleep, we always get together with our heads facing inward and our tails facing outward. When we hear any sound, we swim away immediately.

Our reproductive ability is very poor, with only a few brothers and sisters born every two years on average, and the number of our brothers has also decreased sharply because of human killing and environmental pollution. My second brother has few now.

Look, how smart we whales are. We have time to visit us, sit on us and travel around the world.

Whale's self-report composition 500 words 6 Hello everyone! I am a white whale. You may ask, "How can an animal as big as a whale be described as' unique'?" Yes, I am a real whale, but I am very small. If you think I'm not a whale, then you don't know enough about our whale family!

Let's start with my "big brother" blue whale! This should be known all over the world! It weighs100000 kg and is very powerful. It can kill sharks with one tail and has an extraordinary appetite. It can eat more than 2,000 Jin of small fish and shrimp in one bite. Besides eat small fish shrimp, it also eats seaweed. If it opens its mouth, the algae in that place may be swept away by it.

Let's talk about the "underwater bully"-killer whale! He is a killer. Smaller fish will die after two or three bites. They always hunt in small groups, and when they meet a big blue whale, they will pounce fiercely and bite with their mouths open. If the prey still wants to die, just fill a few more mouths and the prey will die.

Let's talk about our Mobidick. We live in the sea near the Arctic glacier. We are all white and gentle. Adult whales are only 3-5 meters long, which is really a drop in the bucket compared with the big blue whale. Because of my small size, I remember being called a dolphin by a child once!

There is also a polar whale called narwhal. As the name implies, it has a long horn on its head, which can not only hunt and drive away natural enemies, but also play a role in competing for females!

In recent years, our cetaceans have suffered a human massacre. We really want to make friends with human beings, please protect us!

I am a member of the baleen whale family. My name is Haier, and my family lives in a Wang Yang. Humans are used to calling us whales. In fact, we are not fish, but mammals.

In ancient times, the ancestors of whales lived on land like the ancestors of cattle and sheep. Later, the environment changed, and the ancestors of whales lived in the shallow sea near the land. After a long time, their forelimbs and tails gradually become fins, their hind limbs completely degenerate, and their whole bodies become fish-like, adapting to life in the ocean.

I was viviparous and grew up on my mother's milk. I was more than ten meters long and weighed seven tons when I was born. It can grow 30 to 50 kilograms a day and grow into a whale in two or three years. I am three years old and live with my mother all day. Although we have no teeth, it tastes very unusual. Just open your mouth, suck many small fish and shrimp into your mouth together with seawater, then close your mouth, filter the seawater out of the middle of the whisker board, and swallow the small fish and shrimp into your stomach, and you can eat more than 2,000 kilograms in one meal. There is also a whale called toothed whale that lives in the ocean with us. Gu Ming thinks they have sharp teeth. When you meet big fish and marine animals, you jump on them, bite them with sharp teeth and eat them quickly. The natural enemy of our family, the black calf whale, often gathers together to surround a fin whale weighing more than 20 tons. It was eaten in a few hours, so we often avoid killer whales.

Like cattle and sheep, we breathe with our lungs, and when we breathe, we come out of the sea, and the water column formed by the gas ejected from our nostrils is different. Different whales have different water columns: the water column of baleen whales is vertical, thin and high; The water column of toothed whale is inclined, thick and short. Whales sleep every day. When they sleep, their heads are always together. They will find a safe place. Head in and tail out, spread out as soon as you hear anything.

We live happily in the vast sea, and the longevity of our family can generally live for decades to a hundred years.

Hello, everyone, I am a lovely and obedient minke whale. My figure is slender, my back is black and my abdomen is white. The boundary line is wavy or cloud-shaped, and the transition area is gray. The lower sides of flippers and caudal fins are gray, and the dorsal fin is sickle-shaped and tilted backwards. Each side must be black, about 300 ~ 400, so it is called "Blackboard Whale". I am a national second-class protected animal!

From the story of being an elephant in Cao Chong, you may think that elephants are very big, and I am much bigger than them. My weight is about 3000 kilograms, and my length is about 17 meters. My tongue is as heavy as a dozen big fat pigs. People put their hands in my mouth and can't touch my palate!

Our home is in the ocean, and many people call us whales because we are shaped like fish.

Everyone must be curious. We are too heavy. What is our food? To tell the truth, we mainly eat shrimp and small fish, which is a bit troublesome to eat because we have no teeth. When we swim in the ocean, we open our mouths and swallow many small fish and shrimps. We can eat more than 2000 Jin in one meal. When we eat them, we also swallow the seawater together, and then filter out the seawater.

We breathe with our lungs like cattle and sheep, which also shows that we are not fish. Our nostrils grow on the top of our heads, and when we exhale, they will surface. The air from our nostrils forms a column of water, just like a fountain in the garden. The water column we spray is vertical, thin and high.

Every day when our family sleeps, there are always several heads together. We usually find a safer place, head inward and tail outward, and float quietly on the water.

We were viviparous. When we were babies, we grew up eating our mother's milk. These characteristics show that we are mammals. The fin whale is 10 meters long and weighs 7000 kilograms. They can grow 30 kilograms to 50 kilograms a day, grow into whales in two or three years, and generally live for decades to a hundred years.

My name is "whale", but many people don't understand. Call us whales. We are not fish, but the largest mammals in the world.

At first, we lived on land, and our ancestors lived on land like the ancestors of cattle, sheep and monkeys. Later, due to some changes in the environment, after a long time, our forelimbs and tails became fins, and our hind limbs degenerated, and later they were almost like fish.

We are divided into many kinds, mainly divided into two categories: one is baleen whales, the other is toothed whales, which are divided into toothed baleen whales and toothless baleen whales, mainly eat small fish shrimps, and toothed whales mainly eat big fish and marine animals. The killer whale is the most powerful of our kind, and it is called "the tiger in the sea". A fin whale weighing more than 30 tons can eat it up in a few hours.

We breathe with our lungs like cattle and sheep, but our noses are not on our faces, but on our heads, so we must come out of the water to breathe every once in a while. When we breathe, we spit out a column of water. Don't underestimate this water column. Experienced people can judge our kind and size according to it.

We whales are viviparous. It takes about 1-2 years to give birth to a calf. Small whales can grow into big whales in 2-3 years. We grow fast and live long, usually for decades to a hundred years. Many of our species are endangered. In the 20th century, nearly 300,000 of our companions were killed, leaving less than 50 blue whales. So I hope humans will stop arresting us.

Whale's self-report composition is 500 words 10 Hello everyone! I am the biggest animal in the world-whale. I am very big. My tongue is as heavy as a dozen fat pigs! I let you humans sit in my mouth and read with your mouth open. It's still spacious. I can't even touch my palate when I stand up. Many people like to call us whales. In fact, we are not fish, but mammals. Because we are viviparous and breathe with our lungs, these two points can prove that I am not a fish.

There are many kinds of whales, which can be divided into two categories. One is the toothless baleen whale. The other is the toothed whale, which has sharp teeth. We are so old, what should we eat? The baleen whales are mainly eat small fish and shrimp. It swims with its mouth open, and then closes its mouth when it is full of Chinese and western food. It filters seawater with tentacles and swallows small fish and shrimp into its stomach. Toothed whales mainly eat big fish and marine animals. Killer whales are the most powerful toothed whales, which are distributed in the ocean. Black whales in the Atlantic Ocean and Antarctica even feed on blue whales, while killer whales in the ocean mainly feed on sharks.

Adult killer whales are eight to ten meters long and weigh about nine tons! Newborns are also two to two in length. 5 meters, weight 180 kg. Adult killer whales have about 40 to 50 huge conical teeth in the upper and lower jaws, which can swallow a sea lion!

We can also judge what kind of whale it is according to the water column it spews. The water column of baleen whales is thin and high, while that of toothed whales is short and oblique. Whales have a long life span, usually between 80 and 100 years old.

Some classics are extinct, such as the dragon king whale and the mechanical toothed whale. Endangered are blue whales and killer whales. I hope you humans can protect the environment, don't hurt whales, and make whales no longer extinct.

Whale's self-report composition is 500 words 1 1 Hello everyone! I am a baleen whale living in the deep sea. My name is Liang Jieying, and I am a 13-year-old baleen whale. Although I have a tail that looks like a fish, please call me a whale. In fact, we are mammals like you humans.

Although baleen whales have no teeth, I have a beard. When I want to eat in the sea, I will take a deep breath, suck fish and shrimp and seawater into my stomach, then close my mouth, suck up the water with a tentacle board and swallow the fish and shrimp. I tell you, I can eat more than 2000 Jin of fish and shrimp in one meal. In your human world, my meal will cost you more than 20 thousand. If you want to invite me to your house for a few days, I'd better eat first and then pack some food to your house. Otherwise, your family will be ruined by me.

Because I eat a lot, I grow very fast, and I can gain two people's weight in one day. My tongue weighs dozens of big fat pigs. You want to touch me for a thousand years!

My mother is a Moby bastard. She is recognized as a singer. She can change hundreds of voices, and the voices of old people, children and young people can almost be imitated. Look! She also has a music classroom to practice songs!

I heard from my grandfather's uncle, Blue Whale, that the number of whales in our country has decreased sharply due to the killing of human beings and the pollution of the marine environment. There are currently no 50 largest blue whales. Why did you hurt us? People who kill my compatriots have a hard time!

We whales are viviparous. When we were born, we were ten meters long and weighed seven thousand kilograms. It also means that we are the same kind. As long as you don't kill me and make friends, I'll invite you to my house to travel around the deep sea, but you have to buy some professional equipment to come. Give me a call when I go to your home, and just prepare a big swimming pool at your home!

Remember to call me, I'm lonely.

Whale's self-report composition 500 words 12 Hello, I'm a whale. I am the biggest animal in the world! Although we cetaceans have the word "fish" in their names and look like fish, we are out-and-out mammals.

The biggest whale in our whale family is the blue whale. I'm a blue whale, too, but I'm still young, only over 8,000 Jin. An elder in our family weighs 160000 kg, which is the largest and heaviest animal in the world.

Although we live in the sea, I am not a fish. Our ancestors once lived on land, so how did we get into the water? Let me tell you a story: in ancient times, our ancestors and the ancestors of cattle and sheep lived on land. Then the environment changed. Our ancestors lived in the shallow sea near the land for a long time, and their forelimbs and tails gradually became fins, and their hind limbs completely degenerated. The whole body became a fish and adapted to marine life.

Generally speaking, we whales can be divided into two categories: one is baleen whales and the other is toothed whales. Baleen whales have no teeth, while toothed whales have sharp teeth.

Maybe you will be curious, our bodies are so big, what do we eat? Baleen whales are mainly eat small fish or shrimp, which can eat 4,000-8,000 kilograms at a meal. Because there are not so many fish and shrimp in the sea, we often worry about not filling our stomachs. And toothed whales eat baleen whales. Dozens of baleen whales ate more than 30 tons in a few hours and staged a bloody scene of killing each other.

We have a good habit of sleeping every day. When sleeping, we like to put our heads together in a circle and float quietly on the water. If we hear anything, we will remind each other to swim immediately.

We are viviparous animals too. We breathe with our lungs. Let me tell you quietly that we also grew up eating our mother's milk. All these are enough to prove that we are mammals, not fish.

Well, that's probably the case with our whale family. Now we only have more than 50 heads. Please protect us.

Whale's self-report composition 500 words 13 Hello everyone, I am the blue whale, the largest creature on earth. Don't be intimidated by my length of 30 meters. In fact, I am very docile and will not attack others easily. If you sail on the sea and hear a long, boring and penetrating song, it's me singing. My singing can travel far away, and I can cross the sea of 800 kilometers. So, I have a nice name-ocean singer. However, I prefer my other name-Neptune.

Although I am huge, I can still swim freely in the boundless sea. Many people think I am a fish, but they are wrong. In fact, I am a mammal like human beings. I am viviparous and grew up on my mother's milk. I often see a fountain on the sea, which is very beautiful. This is my masterpiece. Don't think that I am playing with water in a naughty way. In fact, when I am breathing, I spray the remaining water in my nose into the sky.

I am a mammal, of course I breathe with my lungs. My lungs are very big. I can stay underwater for a long time in one breath. When I need to breathe, I will surface, and that's when the fountain comes out of the sea. When I'm in a good mood, or when I meet the kind I like, you can still see me dancing at sea.

In the last century, I had hundreds of thousands of similar people living in the sea, and the deep blue sea was our home. However, many people killed and polluted the marine environment, which caused the deaths of many of my brothers and sisters. At this moment, there are less than 50 blue whales living in the global ocean. We have lived on the earth for more than 50 million years. Are we just disappearing?

The beautiful ocean also has a self-interlocking biological chain, and we whales are also an important part of it. If you love the beautiful sea, if you love all kinds of mysterious creatures in the sea, if you love the earth where you live, please love us and protect us!

The whale's self-report composition is 500 words 14. Hello, I'm the blue whale. Many people call us whales, but we are mammals like cows and sheep. We also breathe with our lungs, which are viviparous.

I am very big. My tongue alone is as heavy as a dozen big fat pigs. If I open my mouth, people will stand in my mouth, but I still can't touch my upper jaw when I raise my hand. Four people will sit around the table and read in my mouth, which is still very spacious. How's it going? Am I old?

I have a big appetite. I can swallow about 2 million krill at a time and eat 4000-8000 kilograms every day. If the food in my stomach is less than 20xx kilograms, I will feel hungry. I come out to breathe every 10- 15 minutes. At this time, the height of the water column ejected from my nose can reach about 10 meter, just like a fountain on the sea, and it will make a loud noise like a train whistle.

I sleep every day. When I sleep, we always get together. Find a safer place, head inward and tail outward, form a circle and float quietly on the sea. If we hear any noise, we will swim away immediately.

I am covered in treasure, made of fat and soap, my meat is nutritious, my bones can provide glue, my liver contains a lot of vitamins, blood and heart, and my organs are high-quality fertilizers, so we are hunted by humans and polluted by the sea. It is precisely because of this that humans have killed us in large numbers, making our family on the verge of extinction, and many of our companions have lost their lives.

I hope that after reading my self-report, everyone will immediately stop killing our compatriots and let us live happily together on a loving and violence-free earth, OK?

Whale's self-report composition 500 words 15 I am a very huge animal, big and heavy, mammal, guess what it is? Elephants, dinosaurs, mammoths, no, no, no, more specific. Bigger than an elephant, almost as big as a dinosaur, living in the sea, Dangdang, now you know what it is. Where is my whale family? The largest whale weighs160,000 kg, and the smallest whale weighs more than 2,000 kg. I weigh over 4000 kilograms. We whales live in the sea, but we are not. We are fish. We are out-and-out mammals, because in the early years, our ancestors lived on the road, but the change of terrain made our ancestors live in the water, and then the forelimbs and tails directly degenerated, which led us to live in the sea. Do you think we need to breathe? That's necessary, otherwise we won't be real mammals. I tell you, I am a toothed whale. I can eat a whale of more than 2000 kilograms in minutes. My jet is thick and short. But there is another kind of fish with a thin and high spray. Do you know what kind of fish this is? That's baleen whale's.

We sleep every day, and every whale family will find a comfortable and clean place to lie quietly on the water. We were alert to the noise and swam away at once. We whales are viviparous, which fully shows that whales belong to a large family of mammals, but I think our reproductive ability is very poor, and it will take a long time to give birth to a calf. Although our life span is very long, many kinds of whales in our family are on the verge of extinction due to human hunting and pollution of the marine environment. "We have lived on the earth for so long. Is this big family going to say goodbye to the earth? So you should protect the environment. Stop us from becoming extinct.
