The information about the blue whale is shorter!

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.

Appearance. The female is larger than the male, 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.

Blue whales generally eat shrimp and small fish, and killer whales generally eat their own kind.

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 blue whale is currently the largest living creature on Earth, and there is no creature that is 100 million times larger than the blue whale. For the blue whale, the largest animal on our planet, the low-frequency sound it emits in the sea can only stretch for a maximum of 80 kilometers, which is a whole double the difference from the monster found this time. Dinosaurs, such as some sauropods, were huge, up to 30 to 60 meters long and weighing up to 50 150 tons.

How does the blue whale live?

One is that whales do not drink seawater, instead, they extract water from their food by metabolizing fats. While their specific range varies from species to species, whales live in oceans around the world. Because whales have a lot of fat in their bodies, they can easily float in the water.

The second is that, like dolphins, whales are believed to be descendants of land animals that have lived on land for millions of years and returned to the water about 50 million years ago. About 50 million years ago, whales walked on land and were about the size of wolves.

The third is that whales have to surface frequently to breathe, so only half of the continent is sleeping. Whale earwax shows the age of the whale, similar to the way tree rings reveal the age of a tree.

Fourth, sperm whales can dive up to two miles deep in the water, and their bodies have unique physiological adaptations that allow them to survive the intense cold and oppressive stress of diving. The blue whale is the largest whale in the world and is also considered the largest animal in the world. Adult blue whales can reach up to 108 feet in length and weigh up to 200 tons.

Fifth, because each type of whale's tail has its own unique characteristics, it allows whale watchers to identify different species from a distance. The blue whale calls louder than a jet engine and can last up to 30 seconds, and the sperm whale is actually the loudest whale in the world.

Sixth, whales have no other natural predators other than humans. Humans have been hunting large mammals for thousands of years for their meat and other raw materials. Sperm whales sleep upright in the water, their noses poking out of the water.
