We live in the ocean, and many people call us whales because we look like fish. In fact, we are not fish, but mammals.
We have many kinds, such as blue whales, white whales, killer whales and so on. But in general, it can be divided into two categories: one is baleen whales, which have no teeth; One is the toothed whale, which has sharp teeth.
I forgot to tell you, I am a blue whale, and my name is "Doudou". My figure is about 30 meters and my weight is about 70 tons. If I open my mouth, I can open it wide enough for ten adults to come in and out freely. Because we stay in the water for a long time, every time we go out for air, our nostrils will spray a water column as high as 15 meters, which is equivalent to the height of your five floors. Seen from a distance, it looks like a fountain. I have great strength, which is roughly equivalent to the pulling force of a medium-sized locomotive. How's it going? Awesome!
We whales are all treasures, my fat can be used to make soap, whale meat is nutritious, whale bones can be used to extract glue, whale liver contains a lot of vitamins, and blood and internal organs are high-quality fertilizers. So, we are hunted by human beings, alas! This makes us fidget! We don't know how many times we protested against this, but you humans always ignored it and lost many relatives. Why? Why? Can't you have a kind heart like Guanyin?
Now, our number has fallen sharply and is almost extinct. Humans! Please don't kill us again.
