whale

Hello everyone, I am a lovely blue whale. I live in the vast sea. Maybe many people think that I am a very big fish, but you guessed it wrong. I am not a fish but a mammal. Our whales, like cows and cattle, breathe in the lungs and are born of the mother. The little whales grow up by the milk of the female whales, which means that we are mammals. My body is spindle-shaped, almost all of my body is blue-blue, my abdomen is light gray, and there are many white spots on the side of the body. I like to eat some nutritious krill, and I can eat more than 2,000 kilograms in one meal. I usually swim faster, 8 to 12 nautical miles per hour, and when I am scared to escape, the speed can exceed 30 nautical miles per hour. Our blue whale is the largest animal in the world. It is larger than the elephant. It is generally 24 meters long and weighs more than 150 tons. My dad is the biggest blue whale. It has a body length of 33 meters, weighs more than 190 tons, and has a tongue weighing 4 tons. It is enough to fill a big truck. It can open a mouth and can hold more than a dozen. Adults are free to enter and exit. We weigh the weight of 32 elephants and more than 300 cows. To transport a blue whale, we need 5 train cars. Our nostrils grow on the top of our heads, and when we exhale, we float out of the sea. The gas ejected from the nostrils forms a water column. The water column we sprayed is up to 10~15 meters.

If you see that the whale spouting water column is vertical, thin and tall, it is our whale; if the jetted water column is sloping, thick and short, it is a toothed whale. Some people can judge our type and size according to the shape of the water column. When we go to sleep, we always gather dozens of whales to find a safer place. The head is facing inward, the tail is facing outwards, and it is surrounded by a circle and floats on the sea. If there is any movement, immediately swim around. Whales have a long life and can live for decades to a hundred years. Whales are all treasures and have high economic value. Due to their large size and rich body oil, whales, skin, bone, meat and internal organs can be used as raw materials for industry, light industry and food processing industry. Therefore, human beings are hunting us, causing our number to drop sharply and become extinct. The living environment of human beings is expanding, and the area where whales live is shrinking. In addition, the living environment of the ocean is deteriorating, and now it is the only remaining in the world. The blue whale has only 200,000 heads. Although the world has completely banned the killing of blue whales, there are still people who are madly killing, so I represent the family of our whales to the world: Humanity, don't kill us! The earth is our common home, and we have the right to live in this blue sea!
