Write a short essay on a whale s self report, and write a short essay on the topic of a whale s self

Hello, I'm a blue whale, and I'm the biggest animal in the world! Don't look at the word "fish" in the name of our whale family, we are real mammals. Our blue whale is the largest of all the animals known to have survived ancient times.

It is about 30 meters long and weighs between 150 and 2,000 tons, which is equivalent to the weight of more than 25 Asian elephants or more than 300 people. The body of our blue whale is pale blue or mouse gray, with pale fine patterns on the back and white spots on the chest, which is beautiful. Our big tail is wide and flat, and our whole body is streamlined, and it looks like a razor, so it's 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 this large lung volume, we can breathe so much less that we only breathe once every 10 to 15 minutes.

When breathing, exhaust gases such as carbon dioxide from the lungs are expelled from the nostrils, and then fresh air is inhaled. Because my body is so big, I eat a lot of things every day, and my favorite food is the 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, epidermis, bones, flesh and internal organs can be used as raw materials for industry, light industry and food processing industry. Because of this, we are hunted down in large numbers, so that our family is on the verge of extinction and many of our companions have lost their lives. Here, I hope that our human friends can live in harmony with us and make our planet vibrant and vibrant.

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.

The water is polluted, there is not enough to eat, and there is a fear of being eaten by others, so when you go home, you can wash up on the shore.

I am a real sea behemoth with an average length of about 26 meters, the highest record is meters, and the average weight is 150 tons. A giant beast of mine needs a lot of food, and our blue whale consumes about 1 million calories a day, which is equivalent to 1 ton of krill, and krill is its bulk food. I swam into the shallows and swallowed mouthfuls of water and krill.

1 Krill is filtered out by a tongue that acts as a piston, which forces water out through baleen that resemble a large sieve structure that hangs on either side of the palate. Our tongue is more than 3 meters thick, and it weighs more than an elephant.
