Blue whale's statement.
Hello everyone, I am a blue whale swimming happily in the sea, many people may think that I am a very big fish, but you guessed it wrong, I am not a fish, I am a mammal. Like cattle and sheep, we whales breathe with lungs and are viviparous, and calves grow up on the milk of female whales, which shows that we are mammals. My body is spindle-shaped, almost all of my body is blue, my belly is light gray, and there are many white spots on the sides.
My favorite thing is to eat nutritious krill, which can eat more than 2,000 kilograms in one meal. I usually swim fast, up to 8,12 knots per hour, and when I am frightened and run away, I can swim at more than 30 knots.
Our blue whale is the largest animal in the world, with a general body length of 24 meters and a weight of more than 150 tons. My dad is the largest blue whale, it can reach 33 meters long, weigh more than 190 tons, and weigh 4 tons on one tongue, enough to fill a large truck, and it can accommodate more than a dozen adults as long as it opens its mouth. We weighed the weight of 32 elephants and more than 300 cows, and it would take five train cars to transport a blue whale.
Our nostrils grow on the top of our heads, and when we exhale, they rise to the surface, and the air that comes out of our nostrils forms a jet of water, which is up to 10 15 meters high. If you see a whale spewing out of the water column vertically, thin and tall, it is our baleen whale; If the jet of water is sloping, thick and short, it is a toothed whale. Some people can judge our type and size based on the shape of the water column.
Our whole body is full of treasures, with high economic value, because of our large size, rich in oil, whale baleen, skin, bones, meat, internal organs can be used as raw materials for industry, light industry, food processing industry. So humans are hunting us, causing our numbers to plummet and endangered, the living environment of humans is constantly expanding, and the area where our whales live is also shrinking; Coupled with the deterioration of the living environment of the ocean, there are now only 200,000 blue whales left in the world. Although the killing of blue whales has been completely banned in the world, there are still people who are killing like crazy, so on behalf of our whale family, I appeal to the world:
Humans, stop hunting us! The earth is our common home, and we have the right to live on this blue planet.

Classification: Regional.
Blue whales, also known as "razor whales", belong to the class Mammals, cetaceans, and baleen whales. They live in the ocean and like to live in groups, usually migrating in groups of several or dozens of heads. In the Southern Hemisphere, it swims to warm waters near the equator every year to reproduce and overwinter.
In summer, they make long journeys to seek bait near the ice floes around Antarctica; In the northern hemisphere, it inhabits the northern half of the Atlantic Ocean, up to the ice floe zone in the north, and in the Pacific Ocean, it can reach the Aleutian Islands in the north, and part of it enters the coast of our country.
The blue whale has a spindle-shaped body, almost all of its body is blue-blue, and its belly is light gray, with many white spots on the sides of its body. It is a nutritious krill staple food and eats a large amount. It usually swims at a fast speed of 8 12 knots per hour and can swim at speeds of more than 30 knots when it is frightened and absconding.
Among the more than 1 million species of animals that exist in nature, the blue whale can be called "the world's largest" in terms of its size. The body length is generally 24 meters, and the mass is more than 100 tons. The largest blue whale can reach a length of 33 meters and a mass of more than 190 tons.
Roughly equivalent to 32 elephants (the largest animal on land with the mass of multiple cows. Whalers once caught a blue whale in Antarctica, producing 61,43 tons of whale meat, 36,38 tons of fat, a heart of 430 kilograms, a liver of 1 ton, a tongue of 3,09 tons, a stomach of 100 kilograms, lungs of 500 kilograms, a mass of intestines of 1,49 tons, and a total of about 8,100 tons of blood. It would take 47 four-ton trucks or four to five train cars to carry it away.
The strength of the blue whale is second to none among all kinds of animals in the world, and it is known as the "Hercules" of the animal kingdom. The tide it breathes is spectacular, with a column of water up to 10 to 15 meters high. Some people estimate that the total power emitted by the physical strength of a huge blue whale can reach about 1,300 kilowatts, which greatly exceeds the power emitted by the main engine of the medium-sized whaling department, and is similar to the power emitted by an ocean-class whaling ship.
Blue whales are full of "treasures" and have high economic value. The body is rich in oil, and whale baleen, skin, bones, meat, and internal organs can be used as raw materials for industry, light industry, and food processing industry. Since the 30s of this century, the number of blue whales has plummeted and become endangered, and it is now completely banned.

I am the blue whale, which is the largest animal in the world. I can stand 50 people on my tongue, my heart is the size of a car, and a baby can crawl through my arteries. I was heavier than an adult elephant at birth and grew rapidly, gaining 90 kg every 24 hours.
It is said that one of my predecessors died in Antarctica, when she weighed 170 tons, was 33,58 meters long, and was the length of three double-decker buses. I really wish there was a rod scale that could weigh me and see how much it weighed now, and if it was time to **. Many people call me a whale, but I just look like a fish.
I am a mammal, breathe with my lungs. If there is a sudden rise of a long, straight, long, and visible column of water on the calm sea, it is very spectacular, and it may be that I am emerging to change the fresh air.
In the sea, shrimp is my staple food. With a big appetite, I eat an average of about 4 tons of small fish and shrimp every day. When I open my mouth, I suck in the small fish and shrimp along with the seawater, and then squeeze the abdominal cavity to squeeze the seawater out of the whiskers, and the fish and shrimp are filtered out, and then enjoy the food.
Let me tell you, I am a treasure all over. Meat can be eaten, fat can be made into soap, bones can be made into glue, even liver contains a lot of vitamins, and blood and internal organs can be used as high-grade fertilizers. But some greedy people hunted us in large numbers, and now my family has a population of less than 50 people, and the blue whale family, which has lived for hundreds of years, is about to become extinct.
I feared misfortune and cried out: Help us!

Hello, I'm a blue whale and I'm the biggest animal in the world! Don't look at the word "fish" in the name of our whale family, in fact, I was born viviparously and grew up drinking the milk of a mother whale. It is a mammal.
It is the largest mammal in the world, found in all oceans and seas of the world. I can reach about 30 meters in length, weigh about 170 tons, and can open my mouth to the width of 10 adults. I eat two to four tons of plankton a day.
And we have a long lifespan, we can live from decades to a hundred years. We sleep together to be on the safe side, always sleeping together, head in, tail outward, in a circle.

Gibbon whales. It is also called the humpback whale, the body length is about 15 meters, the weight is 25 tons, the back is black, the other parts are gray, the pectoral fin is very long, like a pair of giant arms, the body is thick and short, and the hunchback is bent over, so it gets this name. It is present in very small quantities and has become a rare species in the Antarctic seas.
Sperm whale. Also known as the true beetle, the body length is 18 25 meters, the weight is 20 25 tons, the largest is 60 tons, and it is the largest one among the toothed cetaceans. It has a grayish-yellow body color, a particularly large head, wedge-shaped, accounting for 1 3 of its body length, a stubby body, slow and clumsy movements, and easy to hunt.
The existing population has dropped from 850,000 to 430,000.

It is divided into the following three subspecies: Intermedia Burmeister (1871) Southern blue whale is found in the Southern Hemisphere; females are 23 24 m long, males are 22 m long, sexually mature, and physically mature body lengths are 26 27 m and 24 25 m respectively; Northern Blue Whale (Musculus Linnaeus, 1958) The Northern Blue Whale is found in the North Atlantic and North Pacific Oceans. The female of the northern blue whale is 21 to 23 m long, and the male is 20 to 21 m long, and is sexually mature, and is physically mature at 25 and 24 m long, respectively; Brevicaukta Ichihara, 1966 Brevicaukta Ichihara, a small blue whale found in the subantarctic waters of the Indian Ocean and the Southeast Atlantic.
The female is 19 meters long, the male is slightly less than 19 meters long, and the male is 22 and 21 meters long, respectively. The blue whale is one of the seven species in the genus Angle. But DNA sequencing analysis shows that blue whales are physlogially closer to humpback whales and gray whales than other species in their genus.
At least 11 documented adult offspring of blue whale finwhale hybrids. Aronson and Gelberg (1983) argue that the difference between blue whales and finned whales is similar to that between humans and gorillas. It is generally believed that the anchocedae separated from other families of the suborder baleen whales as early as the middle Oligocene.
m.musculus, which includes populations in the North Atlantic and North Pacific; b. m.
intermedia, which includes populations of the Southern Ocean; b. m.brevicauda (also known as pygmy blue whale), which includes populations in the Indian and South Pacific Oceans.
Earlier authorities referred to the Indian Ocean population as a separate subspecies b m. indica。
But unlike the other three subspecies, the name of the last subgroup does not appear on the Red List of Endangered Species. At present, the two classification methods are still questioned by some scientists; Genetic analysis revealed that there were only two subspecies. The species name musculus** is Latin for "strong", but it can also be understood as "little mouse".
Linnaeus probably knew that he had done the naming of the species in his seminal work of 1758, and then humorously used this ironic pun. Blue whales also have other common names such as sulphur-bottom, sibbald'S Rorqual, greatest blue whale and greatest northern rorqual, names that have been forgotten in recent decades.

The blue whale is the world's largest mammal and is found in all oceans and seas around the world. It can reach a length of about 30 meters and weigh about 170
A mouth can be opened to a width that allows 10 adults to enter and exit freely. The blue whale has a light blue dorsal spine and a folded belly with ochre-colored yellow spots. Its tail is broad and flat, and it can.
Swinging freely and flexibly in the water, it is both a forward power and a rudder, and can reach speeds of up to 27 kilometers per hour. The predation mode of blue whales is "devouring", and the main food is small shrimp
Plankton such as jellyfish, diatoms, etc. It often opens its mouth on the surface of the water and swallows the shrimp and seawater in its mouth, and then closes its mouth to filter out the seawater and swallow the small shrimp into its stomach.
A blue whale eats about 4 tons of small krill per day.
If it has less than 2 tons of food in its stomach, it will be hungry and panicked, as if it will never have enough to eat. So it often dives to a depth of thirty or forty meters in search of food.
Because you stay in the water for a long time, every time you float to the surface for ventilation, a jet of water about 15 meters high shoots out from your nostrils, and it looks like a fountain from a distance. The strength of the blue whale is great, about the same as the pulling force of a medium-sized locomotive. It is said that a blue whale once dragged a 27-meter-long whaling speedboat for more than 70 kilometers, and the speedboat was moving backwards at full speed.
Blue whales breed during the winter months. The mother whale is pregnant.
A calf was born a year later. The newly laid calves are about a meter long and weigh about 6 tons, and they are fed for 24 hours.
It can gain about 100 kilograms of weight, an average of about 75 grams per minute. After 7 months of lactation.
It can reach a weight of about 23 tons, a body length of about 16 meters, and begins to learn to swallow various plankton with its mouth open.
The baby blue whale is not considered an adult until it is 5 years old, and its lifespan is about 20-30 years.
The blue whale is full of treasures, and its fat can be used to make soap; Whale meat is delicious and edible, and rich in nutrients; Whalebone can be refined with glue; Whale liver contains a lot of vitamins; Blood and internal organs are also high-quality fertilizers. As a result, blue whales have been repeatedly hunted and killed by humans. At present, the number of blue whales is declining dramatically, almost to the point of extinction.

The blue whale is the largest baleen whale, the longest being a female whale caught in Antarctic waters between 1904 and 1920, with a length of 170 tons.
The appearance of females is greater than males, and the southern blue whale is larger than the northern blue whale. Viewed from above, the snout is wide and flat. The dorsal fin is small, about high, 1 4 places posterior to the body.
The flippers are smaller, accounting for 15% of the body length. The caudal fin is 1 3 to 1 4 wide in body length, and the posterior margin is straight. There are 55 88 stinging grooves, and the longest reaches the umbilicus.
270,395 whiskers on each side. The dorsal body is dark pale grayish-blue, the ventral surface is slightly lighter, and the mouth and beard are black.
Habits. Blue whales feed on plankton and eat krill as a staple. A blue whale consumes 2 4t of food per day. The swimming speed is 2 6 km h during feeding, 5 33 km during migration, and the maximum speed is 20 48 km per hour.
Generally, 10 20 small dives are followed by a deep dive, with shallow dives between 12 20 seconds, and deep dives lasting 10 30 minutes. The ejected fog column is narrow and straight, 6 12m high. Blue whales are sexually mature at about 10 years of age, northern blue whales give birth and mate in late autumn and early winter, and in the southern hemisphere they mate in winter in the south, with the peak in July.
The breeding period is half a year different from the northern and southern hemispheres. The gestation period is 10 to 11 months, and the calf is 6 to 7 m long and weighs about 6 tons. The lactation period is half a year, and the weaning time can reach 16m.
Estimates of the maximum age range from 30 to 80 to 90 years. Whales will courtship by calling.
The lightest blue whale is the newborn blue whale, which is heavier than an adult elephant (weighs about 5 tons), and the rest are very heavy, and there is information below. >>>More
