Can anyone tell me about the blue whale urgently

1. The blue whale is a marine mammal that belongs to the suborder Baleen Whales. There are four subspecies of rambling ants. The blue whale is believed to be the largest known animal ever to survive on Earth, reaching up to 33 meters long and weighing 181 tons.

The blue whale has a slender body and a blue-gray back, although it can sometimes be lighter in the water.

2. Like other baleen whales, blue whales feed mainly on small crustaceans (e.g., krill) and small fish, sometimes including squid. Blue whales usually feed at depths of more than 100 meters during the day and come to the surface at night. Blue whales begin mating in late autumn and continue until late winter, with females usually giving birth every 2-3 years, and after a 10-12 month hail period, they usually give birth to calves in early winter.

It is distributed in all four oceans.

3. The blue whale is not only the largest cetacean, but also the largest living animal, the largest mammal to date. It is generally 22-33 meters long and weighs 150,000-180,000 kilograms, which means that it weighs as much as more than 25 African elephants, or 2,000-3,000 people combined. Fortunately, due to the buoyancy of the ocean, it does not need to work as hard to support its weight as a land animal, and its large body helps to maintain a constant body temperature.

The blue whale has a light blue dorsal spine and a folded belly with ochre-colored yellow spots. With a broad, flat tail that can swing freely and flexibly in the water, it is both a driving force and a rudder, and can reach up to 27 kilometers per hour. The predation mode of blue whales is "devouring", and the main food is plankton such as small shrimp, jellyfish, and diatoms.

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 go back hungry and panic, as if it will never be full. So it often dives to a depth of thirty or forty meters in search of food. When you stay in the water for a long time, every time you float to the surface for ventilation, a jet of water up to 15 meters high shoots out from your nostrils, and it looks like a clear spring from a distance.

The strength of the blue whale is great, about the same as the pulling force of a medium-sized locomotive.

Blue whales breed during the winter months. Female whales give birth to calves a year after they are pregnant. The newly born calf is about a meter long and weighs about 6 tons, and after 24 hours of feeding, it can increase its weight by about 100 kilograms, an average of about 75 grams per minute.

After 7 months of breastfeeding, the young whales can reach a weight of about 23 tons, a body length of about 16 meters, and begin to learn to open their mouths to devour various plankton. The baby blue whale is not considered an adult until it is 5 years old, and it has a lifespan of about 20-100 years.

The blue whale is full of treasures, and the fat can be made into soap; Whale meat is highly nutritious; 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. Now, the number of blue whales is declining dramatically, almost to the point of extinction.

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. If I had less than 2 tons of food in my stomach, I would be so hungry that I would never get enough.

That's why I often dive into the water at a depth of thirty or forty meters and search for 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!

The calves are born near the large Arctic ice floes north of the Atlantic Ocean. Do you want to know how they were born? Then please go to Garniford, Mexico.

Let's go and see the Leah Peninsula! Because the calves are born in the "shallow sea lakes" in that area. Most of these "shallow lakes" are bays of the inland sea, consisting of:

A narrow exit and a large one is also connected. Because the lake is shallow, Mexico's solar energy heats the lake. Each year, a pod of whales departs from the North Pole and swims along the coast of the Americas to the tropics, with males leading the pack and females trailing. Why do whales do this trek? This makes it because the young whale is afraid of the cold.

They are too small, weighing only 700 kilograms each.

The soon-to-be-mothered whale came to the "shallow lake", where its calf was about to be born. The mother whale gave birth well, but there was always one by her side.

A "midwife", why is that?

It turns out that the calf does not know that it is a mammal that breathes with its lungs. Whereas, mammals are meant to breathe air, so it has to float from time to time.

Ventilation on the surface of the water, which requires it to move forward in the water in an undulating manner, that is, after swimming in the water for a while, then surfacing to the surface to take a large breath of air, and then.

Dive into the water. Since it was born in water, why can't it stay in the water for a long time? Because if it stays in the water all the time, it will suffocate.

As soon as the calf was born, the midwife, who was the midwife, immediately approached the mother whale and, together with the mother, clamped the calf tightly between them and held it.

Lift out of the water two or three times. With such training, the young whale will form a conditioned reflex and will henceforth be as serious as a large whale.

Swimming. The young whales spend the necessary period in the "shallow waters" before the families swim back to the north in peace.
