The whale s self description is between 1000 and 2000 words

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!

I have a huge white body with soft and flexible white fins. My teeth are big, but they never hurt humans.

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

I love humans, and our whole family wants to be friends with humans. I hope you do the same. Only when we live together in harmony will Mother Earth be rejuvenated.

Statement 2: The sea is home to many creatures, and I am one of the little blue whales.

Many people have seen an elephant on land and think it is a very large animal, but in fact, we whales say that it is the largest animal on the planet. Our family weighs about 160,000 kilograms at its most, and even the smallest whale weighs 2,000 kilograms!

We are covered in treasures, and the whale skin has a soft texture and surface. It has fluff and leather with patterns, which is suitable for making clothes or leather bags. Whale fins can be used to make umbrellas, bras, bow ties, and cigarette cases.

Whale droppings and bone meal are fertilizers rich in ammonia and phosphorus. Bone glue can also be extracted from whalebones, which is used as a raw material for processing photographic films. Whale liver is very rich in vitamins.

Baleen and whale teeth can be processed into medical devices or handicrafts. Because of this, we are now on the verge of extinction due to overkilling.

Human friends, we are willing to live in harmony with you, and we hope that you can give us the space to move freely!

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".

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.

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 nostrils grow on the top of our heads, and when we exhale, they rise to the surface, and the air that comes out of our nostrils forms a jet of water, which is up to 10 15 meters high. If you see a whale spewing out of the water column vertically, thin and tall, it is our baleen whale; If the jet of water is sloping, thick and short, it is a toothed whale. Some people can judge our type and size based on the shape of the water column.

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.

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.

How are calves born?

The calves are born near the large Arctic ice floes north of the Atlantic Ocean. Do you want to know how they were born? Then please go to Garniford, Mexico.

Let's go and see the Leah Peninsula! Because the calves are born in the "shallow sea lakes" in that area. Most of these "shallow lakes" are bays of the inland sea, consisting of:

A narrow exit and a large one is also connected. Because the lake is shallow, Mexico's solar energy heats the lake. Each year, a pod of whales departs from the North Pole and swims along the coast of the Americas to the tropics, with males leading the pack and females trailing. Why do whales do this trek? This makes it because the young whale is afraid of the cold.

They are too small, weighing only 700 kilograms each.

The soon-to-be-mothered whale came to the "shallow lake", where its calf was about to be born. The mother whale gave birth well, but there was always one by her side.

A "midwife", why is that?

It turns out that the calf does not know that it is a mammal that breathes with its lungs. Whereas, mammals are meant to breathe air, so it has to float from time to time.

Ventilation on the surface of the water, which requires it to move forward in the water in an undulating manner, that is, after swimming in the water for a while, then surfacing to the surface to take a large breath of air, and then.

Dive into the water. Since it was born in water, why can't it stay in the water for a long time? Because if it stays in the water all the time, it will suffocate.

As soon as the calf was born, the midwife, who was the midwife, immediately approached the mother whale and, together with the mother, clamped the calf tightly between them and held it.

Lift out of the water two or three times. With such training, the young whale will form a conditioned reflex and will henceforth be as serious as a large whale.

Swimming. The young whales spend the necessary period in the "shallow waters" before the families swim back to the north in peace.

Despite the fact that I am small in the whale family, I am the bravest one, and the fish, shrimp, sharks, and walruses in the sea will scatter and run away when they see me. My home is full of warmth, and when a partner is injured, we fight to help, push him to the surface and escort him to safety. My cousin, the blue whale, is the largest animal in the whale family and the largest living animal in the world, bigger than some dinosaurs.

It looks like a small hill, reaching more than 30 meters in length and weighing 170 tons, which is 30 times heavier than the largest elephant on land!

We are full of treasures, and we are now on the verge of extinction due to overkill. Alas! I really hope that our human friends can treat us well, we love this beautiful and colorful world!

Our brains are the largest and most complex of all animals on the planet, we have strong memories, and we take care of each other in groups. For example, when we sleep, we always have several partners in a circle, with the head facing in and the tail facing outward, to prevent other animals from sneaking up. There are also many singers in our family!

The beluga whale, for example, can make hundreds of sounds that are endlessly varied. It is a rare pleasure to be able to listen to the beluga whale singing with your own ears!

We are willing to live in harmony with our human friends, and we also hope that our human friends can give us the space to move freely.

Whale's Statement (1).

hi!Hello friends! I'm baleen whale in 3020 and my name is Sally.

I live in room 2080 in the deep sea area, which has beautiful corals and delicious food. oh!Look!

My keeper came and brought me a big bucket of my favorite fish and shrimp, which were so delicious and cute that I didn't know how to eat them.

After a delicious lunch, the keeper put on a multi-functional translator for me and let me learn a foreign language with my friends. After hard work, I can now talk to humans, which is a very good result among my friends!

Next is the math class, and the keeper helps us adjust the translator so that we can understand the math. When we graduate from here, we'll be able to "add, subtract, multiply, and divide"!

However, my favorite is the ** class, where the keeper waves the stick in his hand and we "sing" sweet songs with our unique voices.

Nowadays, technology is constantly updated, and our lives are becoming more and more rich and interesting. However, at the end of the day, the keeper will separate us one by one, so I will be very lonely, and when the time comes, you must come and play with me more often!
