Tell you, I'm the most famous whale in the world. Hey, my children, don't think that we whales are fish, if you do, then you are very wrong, we whales are mammals. Also, I'd like to reveal a little secret to those who think I'm a fish:

It's time to 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! begging

The self-report of the stationery box.

I'm wearing a blue coat with a white trim on it, and Bugs Bunny is wearing a Santa Claus costume and carrying a big bag full of presents, and he has a toy in his hand, and he smiles at the Bugs Buffet banquet for you, as if to say, "This toy is for you." "The little master pasted me a class schedule, and he looked at the class schedule every day and prepared everything for the class in advance.

There are many members in my belly, including a proud fountain pen, a well-mannered pencil, a small and delicate eraser, a ruler with a strong personality, and an automatic pen with five cars of learning. When the little master makes a typo, the eraser will volunteer to jump out. When the little master wants to draw a straight silver line, the ruler will not hesitate to pop out.

When the little master wants to write the pen, the pen will come out quickly. But I have the most credit for stationery. I remember one time, I fell to the ground, my nose was bruised and my face was swollen, but the stationery inside was unscathed.

Even though I'm very old, the little host still likes me.

For example, the number of words of air conditioning can be written as air conditioning, which plays a vital role in this family. Then describe.
