A self statement of more than 300 words is required

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 am the blue whale, which is the largest animal in the world. I can stand 50 people on my tongue, my heart is the size of a car, and a baby can crawl through my arteries. Don't look like fish, in fact, we are not fish, we are mammals.

Since ancient times, we have slowly evolved into fish in order to adapt to life in the ocean. Our nostrils grow on the top of our heads, and when we breathe, we emit a powerful jet of water, which is more beautiful than a fountain! I was heavier than an adult elephant at birth and grew rapidly, gaining 90 kg every 24 hours.

It is said that one of my predecessors died in Antarctica, when she weighed 170 tons, was 33,58 meters long, and was the length of three double-decker buses. I really wish there was a rod scale that could weigh me and see how much it weighed now, and if it was time to **. Many people call me a whale, but I just look like a fish.

I am a mammal, breathe with my lungs. If there is a sudden rise of a long, straight, long, and visible column of water on the calm sea, it is very spectacular, and it may be that I am emerging to change the fresh air.

In the sea, shrimp is my staple food. With a big appetite, I eat an average of about 4 tons of small fish and shrimp every day. When I open my mouth, I suck in the small fish and shrimp along with the seawater, and then squeeze the abdominal cavity to squeeze the seawater out of the whiskers, and the fish and shrimp are filtered out, and then enjoy the food.

Let me tell you, I am a treasure all over. Meat can be eaten, fat can be made into soap, bones can be made into glue, even liver contains a lot of vitamins, and blood and internal organs can be used as high-grade fertilizers. We live a long lifespan, from a few decades to a hundred years!

But some greedy people hunted us in large numbers, and now my family has a population of less than 50 people, and the blue whale family, which has lived for hundreds of years, is about to become extinct. I feared misfortune and cried out: Help us!

Hello everyone, I am a lively and cute baby killer whale, just nine months old, growing in the beautiful and rich Yellow Sea of China, weighing 3,000 kilograms. Many people call us whales, but in fact, we whales are mammals. Once upon a time, our ancestors lived on the vast land, like other mammals.

However, due to changes in the environment, we had to leave our homeland and come to the beach to survive. After many more years, the forelimbs and tails of our ancestors gradually became ji, and the hind limbs completely degenerated, gradually adapting to the marine environment. In addition, many physiological characteristics such as lung respiration and viviparity also prove that we are mammals.

There are more than 80 species of whales, and you humans have classified us, and there are two divisions, the first one divides us into baleen whales and toothed whales, and we killer whales belong to the second species; The second type divides us into half-open whales, eight-open whales, and twelve-open whales, and we killer whales still belong to the second type. For the sake of time, I will only introduce the first division today. As is customary, let's start with baleen whales!

Baleen whales are big guys like blue whales, sperm whales, etc., they have no teeth, only whiskers, no resistance, can only live by eating small fish and shrimp. And our toothed whales are different, all of our toothed whales are martial arts masters in the ocean, and our killer whales have reached the point of seeking defeat alone, and our sharp teeth are our unique weapons. When we swim in the ocean, all the animals stay away, and once we find it, then you should make a will.

You might say, "You can't eat big guys like blue whales or sperm whales?" "Actually, those guys have almost no other advantages except for their strength, so of course, they have become our meal, and some people say that we are cruel, in fact, if we hadn't eaten those old and weak whales, perhaps, our whale family would have been in a mess.

However, we toothed whales, especially our killer whales, are too good for you humans, we never hurt you and do a lot for you. Once, a colleague of mine wrote to me that he had finally become the captain of a ship. In fact, almost every killer whale has experienced this position.

This is the duty of putting one or two people on our backs, and we carry the tourists around the sea according to the instructions of the animal trainers. However, you humans also bring us comfort. You've worked hard to develop our potential and taught us what it means to have two or more movements and fuzzy movements that gorillas don't understand.

In addition, a British ** enthusiast also planned a "concert" for us! Alright, that's all for today, goodbye!
