Sperm whale's self-report composition is 800 words

Everyone has the experience of writing a composition in study, work or life, so you are familiar with it. Writing is a transition from internal speech to external speech, that is, from a compressed and concise language that you can understand to a developed and standardized grammatical structure that others can understand. You always have no way to write a composition? The following is 800 words of the self-report composition of sperm whale compiled by me. Welcome to read the collection.

Sperm whale's self-report composition is 800 words 1 hi! Hello, I'm a sperm whale. My English name is Whale. I belong to physeteridae, an suborder of toothed whales. Seeing my name, you must think I am a member of the fish family. "No, no, no" If you think we are fish, you are all wet. We cetaceans belong to mammals! Because we are viviparous, like other mammals, we grew up drinking our mother's milk when we were young. Of course, we also breathe with our lungs. We sperm whales mainly live in the sea area between 70 degrees north and south latitude.

Let me tell you a secret. I'm the biggest one in the suborder Toothed Whale. The maximum length of male sperm whales is about 23 meters, and the maximum length of female sperm whales is about 17 meters, weighing between 40 and 60 tons. By the way, I also have a nickname "Spearhead Whale" because my head is very huge. So you must think I look strange. To use an idiom to describe it is top-heavy and looks like a giant tadpole. I am also called "submarine" because our sperm whale can easily dive into the deep cold and dark sea. How's it going? Isn't it amazing?

Because many humans know that we sperm whales are full of treasures, and we are slow and easy to be caught. Therefore, human beings keep killing our brothers and sisters, which leads to our "family destruction". Sadly, so far, our sperm whale population has dropped from 850,000 to 200,000. All this is related to our sperm whale's love for giant squid. Giant squid is one of the three treasures in Long Xianxiang. We ate squid, but we couldn't digest its parrot mouth. At this time, the end of our large intestine or the beginning of rectum is stimulated, causing pathological changes, producing a gray or black secretion, and gradually forming a thick dark substance in the small intestine, called "Long Xianxiang". This smell is unpleasant at first, but it will become fragrant after a while. It is not only the best fixative for perfume, but also a valuable source of traditional Chinese medicine. The other two treasures are: first, my meat tastes as delicious and nutritious as beef. Second, my tough skin is the best raw material for making leather.

So here we loudly appeal to human beings: dear human beings! Although I am full of treasures, please protect us with your love and be merciful! Because the earth is our common home, and we are all children of Mother Earth, let us live in harmony and happiness in this beautiful home of the earth.

Sperm whale's self-report composition 800 words 2 Hello! Everyone! Hello, everyone. My name is Laner. I am a sperm whale living in the ocean. I am 12 years old this year. I am about 13 meters long and weigh 66 tons. I am good-looking and my body color is harmonious: my back is pure black and my abdomen is silver gray. The figure can be regarded as the best among sperm whales.

At home, I have a mother in her thirties and countless brothers and sisters. I am the youngest whale in my family. Although I have many brothers and sisters, I still like my sixth sister, Lan Lan. She is my closest sister and never loses her temper with me. Naturally, I am very affectionate with her.

As a sperm whale, I am very proud, because the sperm whale is the "diving champion" among whales! Every member of my family swims very fast, and the speed can reach 12 nautical miles per hour, but we are not only fast, but also often hold our breath and dive 1.5 hours because of hunting prey, and we can dive to the deep sea of 2200 meters! I was born in the family, and I swim very fast!

We sperm whales are fierce and like to eat giant cephalopods, especially squid. It's delicious, and it's really delicious on earth My sister Hai and I often go to the deep sea to kill squid, and then take them home for a good meal. I really enjoy it!

I think everyone knows musk, a precious medicinal material in China! But few people know the secretion in our sperm whale-the precious medicinal material "Long Xianxiang"! Why is "Long Xianxiang" in America! In order to study this problem, I went to ask my sister. Sister said: we swallowed the giant squid in one gulp, but we couldn't digest its parrot mouth. They gradually form a thick dark substance in our small intestine, which is massive and weighs100-1000g, and some of them are 420kg. Its maximum diameter is 165cm, and this substance is Long Xianxiang. When Long Xianxiang first came out of our bodies, it was very unpleasant. After drying, it is amber, sweet and sour. It doesn't have much fragrance, but it smells like musk when burned, and it is farther than musk. The smell it smokes is lasting, which is also the origin of our sperm whale name. Oh, yes, it is said that Long Xianxiang was discovered in ancient China. It seems that fishermen caught it in the sea. At that time, it was speculated that it was the saliva of the dragon in the sea, which slowly formed into pieces. This is really interesting! "

"Oh, so that's it!" I listened to understand nodded, this just heard my stomach "goo goo" sound.

Look! There are squid there! I have to catch it with my sister! Bye.

I am a sperm whale, living in the deep blue sea. Although the word "whale" has fish, I am not a fish. Maybe someone will ask, "If you are not a fish, what can you be?" This result is unexpected. I am a mammal, the largest mammal in the world. Yes, even the elephant can't compare with me.

We cetaceans are rare animals, breathing with lungs like cattle and sheep, which shows that we are mammals. Four people reading in my mouth around the table will think that my big mouth is a beautiful red castle, but they are worried that I will be insatiable and swallow you up.

Our ancestors used to live on land, but they found that there was not enough food on land. Later, when the environment changed, they lived by the shallow sea. Later, they had fins and could swim like fish. Finally, they evolved into us.

Some people will say, "There is so much food in the sea that you can eat whatever you want. There are beautiful corals and so on, which can be appreciated. You can also jump out of the water, dance ballet and dive. Also, you can spray the fountain, how beautiful it is! What do you have to worry about in such a happy and fulfilling life? "

Hearing these words, we whales sighed deeply. It is precisely because we whales are rare animals that we are hunted by you humans!

I remember a few days ago, my friend died because of you humans. I invited friends to play together the other day. We jump on the sea, form our own way on the sea, and even the aroused waves applaud us. We are happier, spewing out a "fountain", which is spectacular. Just as we left with a smile, we didn't find the fishermen looking at us. These experienced fishermen know that we are sperm whales and precious mammals, so they rowed desperately and came to our side. We were talking when suddenly, with a bang, my partner was hoisted onto the boat. I shouted! "No, run!" My surviving partners and I were frightened and swam to the front desperately, but our partners were still caught. I cleverly hid in the sea, which was a close call!

There is another disaster, which is also caused by you humans. The beautiful, endless blue ocean has lost its luster because of your littering, oil and other stolen goods discharged by refineries, and has become a waste factory, which has gradually extinct rare animals in the ocean, and our whales are no exception.

I hope that human beings can protect our whales, so that there will be no people in the world who only look at immediate interests!

Sperm whale's self-report composition 800 words 4 Hello everyone, my name is sperm whale. Today, I want to introduce myself to you.

I belong to physeteridae, an suborder of toothed whales, and the largest suborder of toothed whales. The male is 23 meters long and the female is 17 meters long. The body is conical, and the upper jaw is blunt, far exceeding the lower jaw. Because of its huge head, my body is short and clumsy, and because there are many people who kill us, now we have dropped from 850 thousand to 200 thousand.

I look strange. My head is heavy and my tail is light, just like a giant tadpole. My huge head accounts for about 1/4- 1/3 of my body length. My whole head seems to be a big box, so many people call me "sperm whale".

My nose is also very strange, only the left nostril is unobstructed, and it is located in the upper left front, and the right nostril is blocked, so the fog column I breathe is sprayed at a 45 angle to the left front. The back of my body is dark black, and the front is silver gray or white. The head is particularly large, accounting for 1/4 ~ 1/3 of the body length. The upper jaw and snout are square barrels, and the lower jaw is thin, narrow in front and wide in back, which is extremely disproportionate to the upper jaw. 20 ~ 28 pairs of conical long and narrow teeth, each pair of teeth has a diameter of 10 cm and a length of more than 20 cm. The water spray hole is on the left side of the front end of the head, only communicating with the left nostril, and the right nostril is blocked, but communicating with the lungs, which can be used as a gas storage box. When breathing, the spray column leans 45 degrees to the left and front. I have no dorsal fin. The flippers are short. The caudal fin is wide, about 360 ~ 450 cm wide. I hope you don't laugh at me.

Ladies and gentlemen, a top-heavy body like me is suitable for diving. Most of us live in the deep sea. Hehe, for me, because I often hunt giant squid, I "hold my breath" 1.5 hours. I can also dive to 2200 meters deep. I am a diving champion among mammals!

We often have sword fights with the biggest invertebrate king squid. The largest king squid 1 8m, weighing1. Five tons. Someone is still watching the fierce scene of my kind fighting giant squid in the tropical ocean! They hit the shallow sea from the deep sea. Either the sperm whale ate the king squid, or the king squid covered the whale's blowhole with his wrist and suffocated the giant whale! In that case, wouldn't our sperm whale become a "good meal" for the king squid? However, most of our sperm whales won.

Because myoglobin with tertiary structure is a necessary condition for our sperm whales to survive in the deep sea, we are keen on big squid, octopus, fish and other foods, not to like it or not, but to ensure that the tertiary structure of myoglobin in the body is stable and not oxidized. Our food is mainly squid, octopus and fish. Squid and octopus mainly eat shrimp, crab, crustaceans and fish. The natural red substance represented by mature shrimp, crab and salmon is astaxanthin. The essence of the struggle against the king squid is to compete for each other's astaxanthin resources, so that we can survive in the deep sea for a long time.

We like swimming in groups of 5 to 10. We usually only have 1 baby per child, and occasionally we have 2 babies. The baby is 4 ~ 5 meters long, breast-feeding 1 ~ 2 years, mature at 7 ~ 8 years old, and the longest life can reach 75 years old!

We hope that humans will stop killing us, so that we can become friends.
