I am a whale, and I am the largest and largest whale in the ocean: the blue whale, also known as the razorback.
As we breathe with our lungs, we cannot stay in water for long. We have to breathe air on the surface of the water from time to time. When you exhale, the air ejected from the hole above your head will fly up to the sky with water, forming a water column, which is very spectacular.
Our bodies are very big and there are eight elephants without me. Although the whale brigade is very heavy, our "boss" is very heavy. A tongue can be as heavy as twenty big pigs, it's great!
We baleen whales eat mainly small fish and shrimp. When we swim, we open our big mouth, suck in small fish and shrimp with sea water into our mouth, then release the sea water from the barbels and swallow them.fish and shrimp. Toothed whales, on the other hand, eat large fish and marine animals, and sometimes even us. They are real traitors.
We must also sleep, always in groups, and as soon as there is movement we will disperse immediately.
I was also born viviparous and grew up suckling my mother's milk. I weighed 6 or 7 kilos when I was born. I can gain 50 kilos in a day and I can become a big whale in two or three years. Our life expectancy is very long, usually a few decades to a hundred years, and sometimes we can live over a hundred years, which is about the same age as the average turtle.
And yes, get to know me.
Don't think I look like a fish. Actually, I'm not a fish, I'm a mammal. We whales are generally divided into two categories: one is the baleen whale, which is very gentle and has no teeth;the other is the toothed whale, which has very sharp teeth and only eats large fish and marine animals, never small fish and shrimp. . And me? This is the adorable baleen whale child who only eats small fish and shrimp.
My father is a killer whale, very fierce, and is known as the “King of the Sea”; where is my mother? She is recognized by everyone as the “Beauty Whale”. She has a very good voice and sings beautifully. Every time we have a singing competition, my mother wins the championship. Look! Mom still practices her singing there!
Huh? There's a little fish fighting with a little shrimp over there! I swam quickly and the small fish was eaten by me in one bite. Where were the shrimp? It also filled my stomach. Because I'm so hungry.
Oh! I forgot to tell you that when we breathe, we are different from other animals. Our nostrilsThey are at the top of our heads. When we breathe, we rise to the surface of the sea. The jets of water we project are more beautiful than water. fountains in the garden!
Another characteristic of our whales is that when they sleep, they form a circle with their heads facing inwards and their tails facing outwards. When they hear a noise, they move away immediately.
This is our family.
&Hello everyone! I am a small whale living in the ocean.
Almost all cetaceans: right whales, dry whales, sperm whales, belugas, dolphins and other whale species have great economic value. Cutting up a razor carcass yields 50 tons of meat, 30 tons of fat and 20 tons of bones.
The largest among cetaceansThe smallest is the river pig, which is closely related to dolphins and resembles a dolphin. It is approximately 1.5 meters long and weighs approximately 50 kg.grams. River pigs, like dolphins, often follow ships and pick up scraps of food thrown into the water.
We have many brothers and sisters, here are one or two.
The onyx-armed whale is about 10 meters long, weighs 7 tons and has a slender body. It is the smallest type of baleen whale, with a population of around 200,000 individuals. The right whale is 18 meters long and weighs around 20 tonnes. It has a slender body, a black back and a gray-white belly.
Sperm whales are also called armored whales. They measure 18 to 25 meters long and weigh 20 to 25 tonnes. They are the largest among toothed whales. Its body is gray in color, its head is particularly large and wedge-shaped, representing 1/3 of the length of its body. Its body is short and thick, its movements are slow and clumsy, and it is easy to hunt. The existing stock went from 850,000 to 430,000.
Hello everyone! Do you know me? Let me tell you that I am the famous whale, famous all over the world. Hey, kids, don't think we whales are fish. If you really think that, you are totally wrong. Also, I want to reveal a little secret to those kids who think I'm a fish: I should take a good organic "nutrition" supplement, hahahaha!
We whales are very large animals. A simple little tongue is as heavy as a dozen big pigs! If we open our mouths, you humans cannot touch the roof of your mouth if you stand in our mouth with your hands. With four people sitting around a table, our mouth always seems very spacious! Hey, look how big we are! Oh, by the way, let me tell you, don't tell this to my ancestors if they know, they will have to criticize me!
We have many family members, buteveryone has their own lifestyle habits. Look, the first to appear is our little brother, the baleen whale. It has no teeth, so its food consists of small fish and shrimp; I know, by the way, they are called toothed whales, so they have extremely sharp teeth. we usually eat large fish and marine animals. This one is our leader - the killer whale. He is very powerful if you make him anxious, he doesn't care about human feelings.
We whales breathe with our lungs. When you exhale, you will float on the surface of the sea and the exhaled breath will form a column of water. But different types of whales emit different water columns: the water column of the small baleen whale is vertical, thin and tall; our toothed whale's water column is sloping, thick and short. Look, we whales have a lot of knowledge!
The way we sleepis also a lot of fun. For safety reasons, we always sleep in groups, heads in and tails out, forming a circle.
We are viviparous and grow by drinking the milk of female whales. We grow very quickly and can weigh 30 to 50 kilograms in a day. And our lifespan is very long, we can live for decades, hundred years.
Living in the vast ocean, I have many brothers and sisters and many friends who swim in the depths of the ocean.
When I am happy, I will surface and say hello to the blue sky and the white clouds; when I am upset, I will dive to the bottom of the sea and ignore everyone who comes to me. When the wind was good and the sun was shining, I would swim to the seashore, come out of the sea, look at the land and the mountains from afar and say to myself: where did our ancestors come from?
To talk about my ancestors, I musts from 450 million years ago.
At this time, ancient lobe-finned fish evolved into amphibians, reptiles, birds and mammals. It was only 70 million years ago that our ancestors differentiated from mammals.
At that time, our ancestors were still on earth. Later, they occupied the ocean and lived in shallow seas. Eventually, they adapted to life in the ocean and evolved into the whales we have today.
We are so fat, so our bellies must be big. With such a big belly, what should we eat? When I eat small fish and shrimp, I first expand my belly and swallow all the sea water in my mouth, then I close my mouth, expel the water and swallow only the food . Why do we eat small fish and shrimp? Because we have no teeth and cannot chew food, we cannot monly eat small fish and shrimp. Even though they are small, there are many of them, so we are not afraid of being hungry.
Did you know? My lungs weigh around 1,500 kilograms and can suck in 15,000 liters of air. I can stay underwater for 18 minutes, due to excessive pressure, not only the sound is loud, but also "fountains" appear on the sea. beautiful! It shoots out more than ten meters high, then spreads out and falls onto the sea, splashing from afar, it looks like festival fireworks, it's so beautiful!
It's me, a whale, a mammal living in the deep sea and a good friend of you humans.
