Have no clue when writing a composition? The following is a 400-word composition about whales that I collected for you. Welcome to reading. I hope you will like it.

A composition about whales 400 words 1 Little friend, I am a baleen whale. You can eat more than 2000 Jin of shrimp and small fish in one meal. I am the largest blue whale among whales, and I also have a name: razor whale. How's it going? Interesting! I am a national first-class protected animal. However, human greed has got us into trouble. I'm beautiful!

My body is blue and white. I have no teeth. I swallowed food into my stomach. We are not fish, but mammals. In fact, our ancestors lived on land like cattle and sheep. Later, the environment changed, and our ancestors' forelimbs and tails gradually degenerated. The whole body became a fish and adapted to marine life. Our calf is viviparous.

Our life was originally happy and comfortable, but human greed made us fall into distress. In the 20th century, nearly 360,000 blue whales like me were killed. Our whales are covered with gold. Whale meat is very expensive in high-end restaurants. Rich people order whale meat from restaurants to prove their nobility. And can the sewage and smoke in the factory be eliminated? Why can't human scientists invent tools to eliminate sewage and smoke?

Killers, can you stop killing whales? Many kinds of whales are dying now. Please don't destroy our living environment and hurt my family. Actually, people and animals are good friends, son. Are you right?

Composition about Whale 400 words 2 Whale, it is recognized by mankind as a giant under the sea, a huge and docile animal. Today, I will introduce you!

Fish are marine animals, so are whales. Fish breathe with gills, but whales breathe with lungs. The whale's breathing hole grows on the top of its head. When breathing, whales first expel waste gas from their lungs. When this powerful airflow rushes out of his nostrils, it will make a huge sound, and with the passionate music, a "fountain" will gush out, forming a beautiful scenery on the sea!

Whales have inventions.

Once upon a time, ships had sharp bows, but they never sailed fast, while whales with round heads and brains often caught up with seagoing ships. What is the reason? After repeated research, scientists found that its shape is an ideal "streamline", and the "streamline" has the least resistance in water. Later, designers imitated the shape of whales when designing the hull, which greatly improved the time and speed of sailing on the water.

Military strategists observe the life of whales. Every 20 to 60 minutes, you must surface to breathe. The back arched above the water and then poked its head out of the "fountain", so scientists were inspired to strengthen the strength and thickness of the submarine's raised podium and shell, and treat the shape like the back of a whale. Therefore, it plays a great role in whales.

Nature, a good teacher!

Hello, my name is Lan Lan, and I am also a member of the Blue Whale family. Due to the killing of human beings and the continuous pollution of the marine environment, the number of our family members is decreasing sharply. In the 20th century, more than 360,000 whales were killed and many species were endangered.

We live in the ocean. Because we look like fish, many people call us whales. In fact, we are mammals. In the past, our ancestor was a friend of an ancestor of cattle and sheep. Then the environment changed. Our ancestors lived in the shallow sea near the land. After a long time, our ancestors' forelimbs and tails became fins, and their hind limbs completely degenerated and adapted to life in the ocean.

Maybe you will ask, what can we eat at our age? I tell you, we mainly eat fish and shrimp. When we swim in the ocean for further study, we can open our mouths to suck fish and shrimp into our mouths, then close our mouths, filter the seawater out from both sides of our gills and swallow the fish and shrimp into our stomachs, but I grew up eating my mother's milk when I was a child. This feature shows that I am a mammal. I'll be a whale when I'm over five.

Our life span is very long, generally we can live for decades or even hundreds of years.

Composition about Whales 400 words 4 When I was eating, my mother accidentally mentioned the topic of whaling in Japan, which immediately aroused my interest. I am angry at the shameful behavior of the Japanese who oppress China. This earthquake filled our life with "Japan, Japan". Their whaling behavior made me furious.

"Japanese people love to eat sashimi. They are all island countries, so they naturally eat more seafood. So whaling is forbidden ... "My mother told me solemnly. With a strong sense of justice, I immediately thought that China and Japan are close neighbors across the sea. What if the whales are eaten by the Japanese in the future? So he said indignantly, "The Japanese eat whales in their country, but they can't eat whales in China. Whales are also protected animals! The Japanese are really bad. " Mother said, half crying and half laughing, "Our own whales swim in the Sea of Japan, which is beyond our control!" " Japanese whaling is also in its own territory, and we can't participate in other countries' internal affairs! ""Then ... let them see clearly that whales in China can't be caught! " "Then can you tell which whale is from China and which is from Japan?" "Very simple, Chinese whales are just. They have yellow stars on their backs and are fluent in Chinese. And Japanese whales are very insidious, with red spots on their backs and can speak Japanese ... ""Hahahaha! " Before I finished, my mother was already laughing. Laugh and explain to me the problem of Japanese eating whales. ...

Alas, my common sense is still insufficient. Otherwise, how could I make such a low-level joke about "Chinese and Japanese whales"?
