The self-report of the blue whale (300 words will do! )

I am a whale, and I am the largest whale in the ocean-the blue whale, also called the razor whale.

I live in a vast ocean. I have many brothers and sisters and many friends, roaming in the deep sea.

When I am happy, I will float on the sea in Shanghai and say hello to the blue sky and white clouds; When I'm upset, I dive to the bottom of the sea and ignore anyone who comes to me. When the weather is clear, I swim to the seaside, emerge from the water, look at the land and mountains from a distance and think: Where did our ancestors come from?

To talk about my ancestors, we have to start from 450 million years ago.

At that time, the ancient bearded fish evolved into amphibians, reptiles, birds and mammals. It was not until 70 million years ago that our ancestors differentiated from mammals.

At that time, our ancestors were still on land, then occupied the ocean and lived in shallow water, and finally adapted to the life of the ocean and evolved into our current whales.

We are so big, we must have a big belly. What should I eat with such a big belly? When I eat shrimp in eat small fish, I first swell up and swallow it with the sea water. Then I shut my mouth, let out the water and only swallowed the food. Why are our shrimps in eat small fish? Because we have no teeth, we can't chew food, so we can only eat shrimps from eat small fish. Although they are small, they are numerous, so we don't worry about going hungry.

Do you know that?/You know what? Do you know that?/You know what? My lung weighs about 1500 kg and can absorb 15000 liters of air. I can stay underwater 18 minutes. When I take a breath, due to excessive pressure, there will be a "fountain" on the sea, which is beautiful! Jet out more than ten meters high, and then spread around, landing on the sea, splashing, looking from a distance, like fireworks in the festival, very beautiful!

This is me, a mammal living in the deep sea-whale, and a good friend of you humans.

Hi! Hello, everyone, I'm a little blue whale from the sea. Father said, "We whales are a big family in the sea and the largest animals. According to my mother, we whales have always been divided into two families, one is the baleen whale family and the other is the toothed whale family. Our blue whale is a member of the toothed whale family. The baleen whale eat small fish shrimp, while our toothed whale not only eats eat small fish shrimp, but also eats big fish and marine animals, and occasionally eats diatoms. When the food in its stomach is less than two tons, it will be hungry. When it is extremely hungry, it will attack baleen whales and eat them. Although the relationship between the two families is not good, they have a common ancestor-walking whales. Walking whales originally lived on land, with limbs and tails. Later, they gradually lived in shallow water. Their hind limbs degenerated, and their forelimbs and tails became fins, which is what they are now. But you can't judge a book by its cover. Although we are like fish, in fact we are not fish. We are mammals, and we are viviparous. Young whales grow up eating their mother's milk and breathing with their lungs, which creates a spectacle of water spraying. Listen to "hoo-". Big brother must be spraying water. Whales look better when they spray water than fountains in the city. A lot of people say that. Ah, my dolphin cousin is here. In recent years, the dolphin family is very prosperous. They can play acrobatics, header and super waves. They are small toothed whales. They are relatives. Ah, beautiful sea, rich sea. Who sings such a beautiful song? Oh, it's a fin whale He is a singer among whales. There are new songs every year, and many people come here. Many composers were inspired and wrote many songs with excellent wounds, but we whales have no vocal cords. This is a secret. I can't tell you for a while. Although we are all well developed, we are all big and each of us is overweight, but we can swim amazingly fast, at a speed of 27 kilometers per hour, which is an astronomical figure. What's more, our blue whales are all treasures, fat can be used as soap, whale meat is rich in nutrition, whale bones can be extracted from colloid, whale liver contains a lot of vitamins, and blood and internal organs are high-quality fertilizers. So we have been repeatedly killed, and now the number of blue whales has dropped sharply.

I am a whale, named Juanbi, a fin whale, weighing 40,000 kilograms, with a length of 17 meters.

Play with friends every day, carefree and have a good life. But it didn't last long. I was caught by a group of scientists while floating on the water to breathe. They covered me with an iron net dozens of times bigger than me, making me unable to move. Those people swarmed, tied me back and put me on two big tripods.

They imposed a cruel criminal law on me. Cutting off my tongue almost killed me. To make matters worse, they compared the weight of my tongue with a dozen big fat pigs. My lungs are full of anger.

They often starve me. Alas, I haven't had enough for several days. In the past, when I was in the sea, I could eat more than 2,000 Jin of fish and shrimp at a meal, but now ... alas.

A few days later, I felt a sharp pain in my body. It turned out that those scientists cut off a large piece of my meat to do experiments. What bad luck I had my tongue cut off and a piece of meat cut off. After all, we are conscious! It hurts us too!

My mouth was pried open by them, and a man stood in my mouth and raised his hand to touch my palate, which made me itch. Several people moved some chairs, sat in my mouth and read around the table. I'm surprised. When did my mouth become their "casual bookstore"?

I really miss living in the ocean. I want to say to mankind: "let me go back!" ! ! "

"Hello, I am an adult blue whale, tall and long ... just now, I was swimming in the sea. You must really want to know me. Ok, let me introduce my physical characteristics first: we are heavier than elephants and bigger than elephants. The largest whale weighs about160 thousand kg, and the small whale also weighs 2000 kg. Once, humans found my blue whale, which weighed 40 thousand kilograms and was 17 meters long. My tongue is as heavy as a dozen big fat pigs and my mouth is still wide open.

In ancient times, my ancestors lived on land like the ancestors of cattle and sheep, and then evolved to live in the sea. Their evolution process is very long. Their forelimbs and tails gradually become fins, while their hind limbs completely degenerate into fish, and then live in the ocean.

There are many kinds of whales, such as killer whales and baleen whales ... including my blue whale, but they are generally divided into two categories, killer whales and baleen whales. Baleen whales have no teeth, while killer whales have hard and sharp teeth. I belong to the toothless baleen whale.

My living habits are also worthy of attention. I breathe with my lungs like cattle and sheep, which means I am not a fish, but a mammal. When I breathe, I have to spray water on the sea, just like a fountain in the park. According to the size and thickness of water droplets, I can judge my kind and size. We need to sleep, too. When we sleep, we will find a safer place. Several heads will sleep together, with their heads facing inward and their tails facing outward. If there is any movement, we will immediately disperse around, so that the enemy doesn't know which one to chase. I was born viviparous and grew up on my mother's milk, which also proves that I am a mammal. When I was born, I was more than ten meters long and weighed more than seven thousand kilograms. I can grow 30 to 50 kilograms a day. Generally can live to 80 to 100 years old.

Our fertility was poor, and it took two years to give birth to a calf. Due to human hunting and environmental pollution, the number of blue whales is less than 50. Our whales have lived in the world for more than 50 million years, and more than 360,000 whales have been killed. Many whales are extinct now.

……

Someone is going to kill me. I'll go first. Help! Someone tried to kill me! "

Hello, everyone, I am an adult blue whale, tall and long … just now, I swam in the sea. You must really want to know me.

Hello everyone! Do you know me? I tell you, I am a famous whale, famous all over the world. Hey, my little friends, don't think we whales are fish. If you really think so, you are all wet. We whales belong to mammals. In addition, I want to reveal a little secret to those children who think I am a fish: it's time to supplement the biological "nutrition", hahahaha!

We whales are very big animals, and a small tongue alone is as heavy as a dozen big fat pigs! If we open our mouths, you humans will stand in our mouths and raise your hands without touching our maxilla. There are four people sitting around a table in our mouth, which is still very spacious! Well, look how big we are! Oh, by the way, tell you, don't say this to my ancestors. If they know, they will criticize me!

There are many members in our family, but everyone has their own living habits. Look, the first one to appear is our little brother-the baleen whale. He has no teeth, so his food is small fish and shrimp. The second one is my younger brother, whose name is needless to say. By the way, it's called toothed whale, and its teeth are extremely sharp, so we usually eat big fish and marine animals. That's our leader, the killer whale. He is very powerful. If he is angry, he will show disrespect!

We whales breathe with our lungs. When exhaling, it will float on the upper sea surface, and the exhaled air will form a water column. But the water column ejected by different kinds of whales is different: the water column of minke whales is vertical, thin and high; The water column of our toothed whale is inclined, thick and short. Look, we have a lot of knowledge about whales!

The way we sleep is also very fun. For the sake of safety, we always sleep in groups, with our heads inward and our tails outward in a circle.

We were viviparous, and we grew up drinking the mother whale's milk. Our growth rate is very fast, and we can grow 30-50 kilograms a day. And our life span is very long, we can live for decades-one hundred years.

After listening to my self-report, you will know something about our whales! If you come to see us in the future, I will certainly treat you warmly!

The whale's self-report (2)

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.

We need to sleep, too. There are always several of us together. As long as there is any movement, we will spread out immediately.

I was viviparous, too. I grew up eating my mother's milk. When I was born, I weighed 6 or 7 kilograms. I can grow 50 kilograms a day and grow into a fat whale in two or three years. Our life span is very long. Generally, we can live for decades to a hundred years, sometimes for more than a hundred years, which is about the same size as a tortoise.

What's the matter? You know me.

The whale's self-report (3)

Hey, everyone, my name is whale, and I am the biggest animal in the world. Many people call us whales because our bodies are like fish. In fact, we are mammals, because our living conditions change with the change of environment (from land to sea). In order to adapt to marine life, our forelimbs and tails gradually become fins, our hind limbs completely degenerate, and our whole body becomes like a fish. We are mammals, because we whales breathe with lungs and are viviparous. When we were born, we grew up drinking our mother's milk.

Our whales are mainly divided into two types: baleen whales with no teeth and toothed whales with sharp teeth.

We whales, like cattle and sheep, breathe through our noses. But our noses grow not on our faces, but on our heads, which many people envy but can't imitate. Put your nose on your head. If it rains, you won't be able to cover your nose, and there will be no congestion! Besides, human science and technology are still underdeveloped. If you want to imitate our whales, I advise you to go home and study for a few more years!

When we breathe, the ejected water forms a column of water, just like a fountain in the garden. Don't underestimate this water column. Experienced fishermen can judge the species and size of whales according to the shape of this water column. The water column of baleen whale is vertical, thin and high, like a huge fountain; The water column of toothed whale is inclined, short and thick.

It's time to feed. I won't talk to you. Goodbye.

Whale's self-report

Hello, everyone, I come from the vast ocean, and my name is whale.

I have a big figure, much bigger than an elephant. Our largest whale weighs about several hundred tons, and the smallest whale weighs two thousand kilograms. My mouth is big enough to hold a big fat pig of thousands of kilograms. My eyes are big and my nostrils are on the top of my head. I look cute.

My figure is like a fish, so many people call me a whale. In fact, I am not a fish, but a mammal. I was viviparous. When I was a child, I grew up eating the milk of a mother whale. This feature shows that we whales are mammals.

There are many kinds of whales in our country, such as blue whales and killer whales. Generally speaking, they can be divided into two categories: one is baleen whales with no teeth, and the other is toothed whales with no teeth. I breathe with my lungs like you humans, which also shows that I am a mammal. After a while, we will float to the surface of the sea and spray water out of our nostrils, just like a fountain in the garden.

Now there are fewer and fewer species of whales, and most of them have become extinct. It is because of your hunting and the pollution of the marine environment that our whale population has decreased sharply. Thanks to the people in the nature reserve, we whales have a peaceful home. Humans! Save us, as long as you don't kill us and pollute the ocean, we whales.

You can settle down!
