Whale s self report essay I want to use it urgently, and the trouble should be fast 450 words

Our blue whale is the largest of all animals known to have survived ancient times. It is about 30 meters long and weighs between 150 and 200 tons, which is equivalent to the weight of more than 25 Asian elephants or more than 300 people combined. The body of our blue whale is pale blue or mouse gray, and there are pale fine patterns on the back, and there are white spots on the chest, which is beautiful.

Our big tail is wide and flat, and the whole body is streamlined, which looks like a razor, so we are also called "razorwhales".

Although we live in the sea, we breathe with our lungs just like other mammals. Our lungs weigh more than 1,000 kilograms and can hold more than 1,000 liters of air. Because of such a large lung volume, we can breathe so much less, about every 10 to 15 minutes that we breathe out of the water.

When breathing, exhaust gases such as carbon dioxide from the lungs are expelled from the nostrils before fresh air is inhaled.

Because my body is so big, I have to eat a lot of things every day, and my favorite food is shrimp. We can devour more than 2 million shrimp at a time, and we can eat 4,000 to 8,000 kilograms a day! If we have less than 2000 kilograms of things in our stomach, we will feel hungry.

Since the scale shrimp is widely distributed in the north and south poles, we have lived in the polar regions for generations, rarely in tropical waters, in order to get enough food.

We are full of treasures, which have high economic value. Our body is rich in oil, and our beard, skin, bones, flesh and internal organs can be used as raw materials for industry, light industry, and food processing industry. Because of this, humans have hunted and killed us in large numbers, bringing our family to the brink of extinction and the lives of many of our companions.

Here, I hope that our human friends can live in harmony with us and make our earth home full of vitality and vitality.

Blue whale's statement.

Hello everyone, I am a blue whale swimming happily in the sea, many people may think that I am a very big fish, but you guessed it wrong, I am not a fish, I am a mammal. Like cattle and sheep, we whales breathe with lungs and are viviparous, and calves grow up on the milk of female whales, which shows that we are mammals. My body is spindle-shaped, almost all of my body is blue, my belly is light gray, and there are many white spots on the sides.

My favorite thing is to eat nutritious krill, which can eat more than 2,000 kilograms in one meal. I usually swim fast, up to 8,12 knots per hour, and when I am frightened and run away, I can swim at more than 30 knots.

Our blue whale is the largest animal in the world, with a general body length of 24 meters and a weight of more than 150 tons. My dad is the largest blue whale, it can reach 33 meters long, weigh more than 190 tons, and weigh 4 tons on one tongue, enough to fill a large truck, and it can accommodate more than a dozen adults as long as it opens its mouth. We weighed the weight of 32 elephants and more than 300 cows, and it would take five train cars to transport a blue whale.

Our whole body is full of treasures, with high economic value, because of our large size, rich in oil, whale baleen, skin, bones, meat, internal organs can be used as raw materials for industry, light industry, food processing industry. So humans are hunting us, causing our numbers to plummet and endangered, the living environment of humans is constantly expanding, and the area where our whales live is also shrinking; Coupled with the deterioration of the living environment of the ocean, there are now only 200,000 blue whales left in the world. Although the killing of blue whales has been completely banned in the world, there are still people who are killing like crazy, so on behalf of our whale family, I appeal to the world:

Humans, stop hunting us! The earth is our common home, and we have the right to live on this blue planet!

Hey, my children, don't think that we whales are fish, if you do, then you are very wrong, we whales are mammals. In addition, I would like to reveal a little secret to those who think I am a fish: I should supplement the biological "nutrition", hahahaha!

Our whales are very big animals, and a small tongue alone weighs as much as a dozen big fat pigs! If we open our mouths, you humans will stand in our mouths and raise your hands and not touch the roof of our mouths; Four people sat around a table in our mouths, and it looked very spacious! Hmph, look how big we are!

Oh, by the way, let me tell you, don't say this to my ancestors, it knows, you have to criticize me!

We have a lot of family members, but each has its own habits. Look, the first one to appear is our little brother - baleen whale, he has no teeth, so his food is small fish and small shrimp; The second one to appear is my sibling, whose name is naturally I don't say you know, by the way, it's called toothed whales, and they have extremely sharp teeth, so we generally eat big fish and sea beasts; That one is our leader, the killer whale, he is very powerful, if you provoke him, he will be reckless!

We whales breathe with our lungs. When you exhale, you have to float to the surface, and the exhaled air forms a column of water. But different species of whales spew different columns of water

The water column of the little brother baleen whale is vertical, thin and tall; The water column of our toothed whale is sloping, thick and short. Look, we still have a lot of knowledge about cetaceans!

The way we slept was also fun. To be on the safe side, we always slept in groups with our heads facing in and tails facing outwards in a circle.

We were viviparous and grew up drinking the milk of our mothers. We grow very fast, we can grow 30 kg - 50 kg in a day. And we have a long lifespan, we can live for decades - a hundred years.

After listening to my own statement, everyone will know something about our whales! If you come to us in the future, I will definitely welcome you!

Whale's self-report.

I'm a whale, and the biggest and biggest whale in the ocean, the blue whale, aka the razor whale.

I live in the ocean, I have many brothers and sisters, and I have many friends, swimming in the deep ocean.

When I am happy, I will float to the surface of the sea and say hello to the blue sky and white clouds; When I was upset, I dived to the bottom of the sea, and no one looked for me. When the wind and the sun were beautiful, I swam to the sea, surfaced, looked at the land and mountains from afar, and thought: Our ancestors came from **?

If you want to talk about my ancestors, you have to start from 100 million years ago.

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

At that time, the ancestors were still on land, and later occupied the ocean, lived in the shallow sea, and finally adapted to the life of the ocean, which evolved into the whale we have now.

We are so big, our bellies must be big, and what are we going to eat with such a big belly? When I eat small fish and shrimp, I first stretch my stomach wide and swallow it in my mouth with the seawater, then close my mouth and press the water out to swallow only the food. Why do we eat small fish and shrimp?

Because we have no teeth and can't chew food, we can only eat small fish and shrimp, although they are small, but there are a lot of them, so we don't have to worry about hunger.

Do you know? My lungs weigh about 1,500 kilograms, can breathe 15,000 liters of air, can stay underwater for 18 minutes, and when I breathe, due to the excessive pressure, not only is the sound loud, but there will also be a "fountain" on the sea, which is beautiful! It sprays more than ten meters high, and then scatters and falls on the sea, making a splash, looking at it from a distance, just like fireworks in a festival, very beautiful!

This is me, the mammital whale that lives in the deep sea, and a good friend of you humans.

First write about the size of the whale, then write about the species of whales, then write about what baleen whales and toothed whales eat, how whales breathe with their lungs, how they sleep, and viviparity, and finally write about the fact that humans think that whales are whales and are drastically reduced by the deterioration of the environment and the mass killing of humans. (Remember, call the whale us and me).

You don't have to copy it, you can use your imagination.

It is best to write down the characteristics, weight, and physiognomy of the whale, and add some imagination.

Think of Moby Dick as yourself. I write down the documents I found.

There's a lot you can write about, for example, you can start with the characteristics of whales, their habits, and you can also mention some of your siblings, and then you can talk about some people who are now going to catch a lot of their companions to talk about in order to eat, and you can tell a story. Or the cruel method of conducting scientific experiments on whaling in Japan, and make your own opinion, and hope to put forward opinions on mankind. That's pretty much it, and the essay is done.

I'm a much bigger animal than an elephant! The largest whale weighs 160,000 kilograms, and the smallest weighs 2,000 kilograms. One of our tongues weighed as much as a dozen big fat pigs, and the four royal limbs were reading books in our mouths around the table, and they looked spacious and hungry.

We live in the ocean, and because we look like fish, many people call us whales. Actually, I'm not a fish, I'm a mammal.

We can divide into two categories, baleen whales and toothed whales. Baleen whales have no teeth and eat mainly shrimp and small fish; Toothed whales have sharp teeth and eat mainly large fish and sea beasts.

Our fertility is poor, with an average of two years before giving birth to a calf. Due to human hunting and pollution of the marine environment, our numbers have been drastically reduced or reduced. The largest blue whale in our whale family, nearly 360,000 were killed in the 20th century!

There are less than 50 left! We have lived on Earth for more than 50 million years, but many species are on the verge of extinction.

We don't have many species left, so why do humans still hunt us? Here, on behalf of the whale people, I shout to the humans: Spare us! Let's live happily!
