White sided dolphin self introduction 400 words, write the autobiography of the white sided dolphin,

Hello everyone, my name is Mengmeng, I live in the Yangtze River, and I swim there. I'm a white-sided dolphin, not a fish, but a mammal. My body was very smooth, with two rows of sharp and thin teeth growing inside my mouth, nearly 3 meters long, weighing 250 kilograms, and a long, pointed mouth.

I also have pectoral fins and fins. I do want fish, but I'm so different from fish. Fish have gills, but I don't.

In half an hour, I would float to the surface, take a breath, and then go back into the water, which would last for about half an hour. Fish don't have a fixed body temperature, my body temperature is constant for a long time, because there is a layer of fat under the skin. Fish have very small brains, but my brain is very developed, and some scientists have said:

My IQ is around that of a gorilla, with 5 00 ml. There are so many fish that are different from me! Don't worry, there's more to come!

Fish are oviparous, but I am viviparous. Although it lives in the water, it is not a fish, but a mammal, a small whale. About 60 million years ago, our ancestors, like their other mammal ancestors, lived on land.

Later, due to changes in the climate and environment, they had to move from the land to rivers, lakes and seas. Over the years, we have gradually adapted to life in the water, and our body shape has changed a lot, and we have become more and more like fish. Please stop preying on us because our numbers are dwindling, please protect me!

Hello everyone, my name is White-sided Dolphin. My body is nearly three meters long, weighs about 250,000 grams, my body is smooth like a hammer, my mouth is long, and my upper and lower jaws have a row of sharp and thin teeth. People say I'm a fish, but they don't know I'm a mammal.

You see fish have gills and can breathe in the water, but I don't have gills, but I have lungs. Breathe on the surface of the water through one of the nostrils facing upward. Also, the body temperature of fish is not fixed, while mine is constant.

I have a thick layer of fat under my skin, which can protect against the cold in the winter fat is thick to five 6 cm long and 1 to 3 more than my body weight. And the fish is oviparous, but I am viviparous like a horse, a cow and a sheep.

searched on the Internet, the quotation of poetry is wrong, Su Shi's Jiang Chengzi is mourning his deceased wife, and it is not suitable here. I am a white-sided dolphin named "Kiki" who has been living in the aquarium for more than twenty years, but I have always been alone, with no partners and no relatives.

Oh! It can't be said that there is no at all, think about it! It turned out that I had a partner named "Zhenzhen", and I talked about life for more than two years, and saw that the wedding was approaching, but Zhenzhen contracted pneumonia and died.

Is this why we white-sided dolphins are going to become extinct? Alas! It's tragic!

Tragic! Zhenzhen, I miss you so much, am I really never going to see you again? Thinking of this, I can't help but think of Su Shi's poem - "Jiangchengzi" has a dream on the twentieth day of the first month: "Ten years of life and death are boundless, I don't think about it, I can't forget it, I am lonely for thousands of miles, there is nowhere to talk about desolation, even if I don't know when I meet, my face is dusty, and my temples are like frost."

Zhenzhen, I really miss the days when we lived in the Yangtze River, how many times have I dreamed of returning to my hometown: "I came to my hometown at night, Xiaoxuan window, I was dressing, I was speechless, but I was disturbed by the envy of a thousand tears, and I expected that every year the intestines were broken and the acres of Li touched: bright moon night, short Songgang." ”

Alas! "The avenue is like a blue sky, and I can't go out alone. "Yes, the vast universe and the muddy earth, why is there no room for us white-sided dolphins to live? It's not fair, the world is cold!

King Zhao's white bones linger in the grass, who sweeps the ** platform more, it is difficult to travel, and he returns. "At this time, my mood is very solemn, since God is destined to let us suffer a catastrophe, I have nothing to say, it is really difficult to survive, it is difficult to live, it is difficult to go to the sky. If I really want to live in such a mess, I would rather "go straight to the sky".

O human beings, evil human beings, you have brought many species to the brink of extinction for your own selfish interests, and you are even extinct, you are satanic demons, but I firmly believe that if you continue to destroy the environment like this, in the near future, you will destroy yourself.
