The structure of the heart of a blue whale. What does a whale eat? Baby blue whales.
The largest animal in the world in our time is the blue or blue whale.
Back in the twenties of the 20th century, in Antarctica - Southern Scotland, a female blue whale was caught, 33 meters long and, judging by its size, weighing more than 150 tons - this is more than the weight of 50 elephants combined.
Around the same time period, a blue whale 30 meters long entered the Panama Canal. In June 1964, the same giant was caught off the Aleutian Islands - 30 meters in length and weighing 135 tons.
Individual animals can be distinguished from typical notches by their tail randomness. When they descend from the surface to depth, they bend their body to a hump, hence their name. Gray whales range from 12 to 15 meters in length and weigh from 25 to 35 tons. They only occur in the Pacific Ocean.
Gray whales are often seen near the coast. It is easy to understand that her body is inhabited by seaweed. Sword whales are recognizable by their black and white body pattern and long lackey on their back. They are from five to ten meters and weigh from three to ten tons. They are found in all seas, but they mainly live in cooler areas. Sword whales are excellent hunters and hunt fish, seals and small whales in groups. The most famous is the "Great Orca", also called Orca.

Endangered life...
According to statistics, the average size of a blue whale in the northern hemisphere is about 22.8 meters for males, 23.5 meters for females. Whales that live in the Southern Hemisphere tend to be slightly larger than their northern counterparts.
The sperm whale is eleven to 20 meters long and weighs between 20 and 60 tons. It lives in the Atlantic Ocean, Pacific Ocean and Indian Ocean and is considered at risk. The beluga or right whale belongs to the family of whales and is between three and six meters long. It lives in the Arctic and subarctic oceans off the coasts of Russia, Canada and Alaska. Sometimes it migrates from the sea to the mouths of large rivers.
Belugas can change their facial expressions and show whether they are happily excited or annoyed. Its white coloring is striking. Newborn animals are gray to brown or black in color, at one year they become blue-gray, and only at the age of five their skin is white.
The whale's body is dark gray or blue with a bluish tint; oddly enough, the whale's skin is gray with a blue tint. There is a pattern on the body in the form of huge spots. Each whale has its own special pattern on its skin, like fingerprints. From them you can identify a specific individual. If you look at a whale from above, through the water, it appears blue. This explains the name of the animal.
Belugas are among the whales and feed on fish, squid, mussels and crustaceans. Because they live close to the coast, they hunt primarily in shallow water to a depth of ten meters. Belugas are very social and live in groups of ten or more animals. During breeding times, groups of several thousand animals gather in river estuaries. After four and a half months of pregnancy, one female gave birth to a calf. The mother breastfeeds for two years.
Is the blue whale the largest mammal in the world?
Animals can be up to 40 years old. Their enemies include polar bears and killer whales. The whales have aged differently. Dolphins, such as the La Plata dolphin, live about 20 years; sperm whales can be between 50 and 100 years old. Click on your favorite styles!
Gabriel from Heilbronn asked this question
There are slightly fewer males than females in these bartenders. And blue whales can be up to 33 meters long. When a calf is born, it is already seven meters long and weighs between two and three tons.
There are more spots on the back half of the body and on the abdominal part, and slightly fewer on the back and front half. The dorsal fin of the blue whale is small - about 1% of the body length and is set back. The head is wide - when viewed from above, with convex edges to the sides. The heart of a blue whale weighs more than 500 kg, the lungs can hold up to 14 m3 of air, and the diameter of the dorsal aorta reaches the diameter of a ten-liter bucket.
Blue whale babies are nursed for six to seven months by their mothers. They drink 600 liters of milk every day! Blue whales achieve their large masses by feeding primarily on plankton and small nymphs such as lucifer crayfish. This may seem a little unimportant, but it's not, because the blue whale weighs up to 40 million bugs in the summer. In winter, however, he lives only on his fat reserves.
The blue whale can dive to depths of up to 300 meters. Usually bartender's whales remain in the upper 100 meters from the sea. On the other hand, blue whales swim very fast and can dive for a very long time. Blue whales can reach speeds of up to 30 kilometers per hour.
In summer, blue whales are found mostly in the waters of the Antarctic, North Atlantic, Bering and Chukchi Seas. It is practically never found in tropical latitudes.
There are very few blue whales left anywhere. They live in small isolated families, most often separately from other relatives.
The whale is the absolute record holder among whales when it comes to diving, it can dive for up to 90 minutes and stay underwater at all times, reaching depths of up to 000 meters - no other whale can compete. Blue whales are found in all oceans, no matter what climate region.
All images and links have been removed from the archive. Whales are not only one of the largest mammals, but also the largest living creatures. Depending on which of the 80 species of whale it belongs to, for example, it weighs as much as a very heavy man or eleven elephants.
In 1959, near the islands of Marion, Crozet, Kerguelen and Heard - in the southern hemisphere, a herd of dwarf blue whales - pygmies - was discovered. This herd numbered about 10,000 individuals. These whales are 3 meters shorter than common Antarctic blue whales, have a shorter tail and are lighter in color.
The common dolphin weighs the least
Dolphins are also members of the whale family, although this is not directly implied due to their size. It is from 1.7 to 2.4 meters in height and weighs up to 130 kilograms. Orca is also known as the orca whale or killer whale and is the largest of all dolphins. Large orcs can weigh up to 9 tons and eat up to 100 kg per day.
One of the best divers - sperm whale
The sperm whale is one of the best divers. It can dive to a depth of 200 meters and remain underwater for an hour. The sperm whale is about 11-18 meters long, and its head is about one-third the length. It weighs between 20 and 50 tons and should consume 3 to 4 percent of its body weight per day.
According to the observations of zoologists, it became clear that pygmies do not migrate to warm waters - the spotting of pygmies, which appears after visiting warm waters, is weakly expressed, which means they could have formed from North Atlantic settlers - the tail of pygmies is also short, like that of Newfoundland blue whales.
Finnish whale - many swimmers
The Finn whale is not only the second largest whale, but also the second largest animal in the world. The Finn whale can reach 25 meters in length and 80 tons in large numbers and consumes 2 tons per day.
The blue whale is the largest of all
The blue whale is the largest whale and also the largest living creature in the world. It can reach 33 meters in length and weigh up to 140 tons, which is about 28 adult elephants. Already a recently born blue whale is at least 8 meters long and weighs about 8 tons.The heart of an adult blue whale has a diameter of about 1.2 m and weighs as much as a whole horse. The blue whale is a real giant. The largest specimens found are over 35 meters in size and even in a dwarf version, blue whales are up to 24 meters long. More interesting facts about the world's largest mammal can be found in this profile.
Thus, there are three subspecies of blue whales: northern, southern and pygmy.
The blue whale feeds on plankton and does not eat fish. The stomach can hold up to 2 tons of crustaceans.
These whales breed offspring every two years - mainly in winter, in warm waters. Pregnancy lasts approximately 11 months. Babies are born weighing about 2-3 tons and a body length of about 8 meters.
Description of the blue whale: an animal of superlatives
The largest in the world averages 24 to 27 meters and reaches a weight of 130 to 150 tons. The heaviest scales so far have even yielded scales weighing 190 tons. The pygmy blue whale is the smallest species of whale, but even it carries it with a maximum length of 24 meters up to 70 tons.
The blue whale's organs are correspondingly large: the heart of a small car is the size of a heart, and the belly can hold about two tons of food. The heaviness of the tongue should not be absent from the profile: on a body weighing about four tons, more than ten people will find comfort.
Female mothers nurse their young for approximately 7 months. During this time, the height doubles - 16 meters, and the weight approximately ten times - 23 tons. Already at one year, a small blue whale weighs 45-50 tons and has a body 20 meters long.
Most often, a blue whale in the process of hunting swims at a speed of 11-15 km/h, but in exceptional cases it can reach speeds of up to 33-40 km/h. But a blue whale can swim so fast for a very short time.
Blue whales are minimalistic when eating
Blue whales have horny plates in their upper jaws - up to one meter long, longer than any other right whale. With these beards, the blue whale filters huge amounts of krill from the water. Krill are about five centimeters in size, crab shrimp. They constitute the main food of the blue whale. Unlike the predatory killer whale, which will even chase creatures its own size, the huge blue whale prefers tiny sea creatures. It devours up to 40 million copies a day.
This, however, it does only during the summer months, which it spends in the nutrient waters of the polar region. In the fall, blue whales make their way to the equator, where they mate and bear offspring. During this time, the blue whale feeds on the fatty scents that are consumed during the summer and hardly consumes any food.
Often people find carcasses of dead whales washed ashore. Scientists still do not know the reasons why whales wash ashore.
Baby blue whales are little giants
A young blue whale is hungry. Blue calves are nursed for six to seven months and drink about 600 liters of milk daily. As her profile shows, blue whale babies are also little giants. At birth, the blue whale weighs two to three tons and is seven meters long.
The blue whale is the largest animal that has ever lived on our planet. The largest animal measured was over 33 m long - a female. Despite its enormous size, the blue whale feeds exclusively on plankton, small crustaceans and small fish. The blue whale has Barten instead of teeth. An adult animal has a food requirement of one ton per day!
In museums all over the world, anyone can see the skeletons of these amazing creatures. Which, even in this form, amaze with their gigantic size. Unfortunately, today a large number of whales have been killed, so they are still endangered. Also, these sea giants may not survive large changes in climate.
When you exhale, the blue whale pushes out a fountain up to 10 meters high. Rare and sad at the same time: a blue whale is recognized on a beach in California. The animal was injured more than 20 m in the collision with the ship. In the fall, giants take over the South Atlantic. When the intense blue waters begin to fill with black spots, the whales have arrived. We must prepare for seven months of jumping into the ocean and tender scenes between mothers and offspring.
Whales delight the eyes of all tourists with their amazing leaps. The bays of Nuevo and San José, which surround the Valdez Peninsula in Chubut, are the habitat chosen by the right whale to breed and suckle its young. The show is within reach of the senses, enough to take you to Puerto Madryn or Puerto Pyramid, 100 km west of Madryn.
Video: Blue whale, weight,...
At the moment, it is known that the largest animal ever living on our planet is the Blue Whale. Accordingly, he is the largest whale among all species of these giants. The blue whale is a mammal. How much does a whale weigh? It’s hard to believe, but the weight of the Blue Whale reaches 180 tons, and such a whale can reach 30-33 meters in length. By the way, the weight of the Blue Whale's tongue is approximately 2.5-3 tons, this weight can be compared with the weight of an Indian elephant. The size of a whale's heart can be compared to a small car - its weight can reach 650 kilograms.
The southern right whale is a huge cetacean. At birth it is from 4 to 6 meters and weighs 3 tons. Women are bigger than men. It is undoubtedly one of the largest animals in the world, and its distinguishing feature is its huge head covered with calluses. These animals come to the waters of Chubut to mate. Gestation lasts a year, and each woman gives birth to only one calf at a time. Two years after birth, the mother whale is exclusively devoted to her offspring. For the first 12 months she breastfeeds her and is not separated from her, and over the next year she tries to learn how to take care of herself.
The blue whale has a gray-blue hue, with spots of various shapes and sizes. Thanks to the ventral folds, whales can take huge amounts of water into their mouths.
Where live?
You can meet a blue whale in every ocean. Depending on the season, they tend to move to different areas of the ocean. There is evidence that some of them are located in the equator region throughout the year. But monitoring their movements in reality is not easy.
From El Doradillo Beach, 17 km from Puerto Madryn along a dirt road, you can easily see mothers playing with their calves for hours. This route can be done by car. Whales begin arriving on these shores between May and June and usually stay until November or December, when they migrate to the southernmost seas in search of food.
Everyone's favorite image, the whale's tail, is therefore used for marketing in T-shirts, mugs, alamans, etc. One of the curiosities of the life of these marine mammals comes from their feeding. They maintain their tons of weight based on the microscopic food they pass through the beards that line their mouths. Whales have no teeth other than beards, which catch krill and plankton as they fill their mouths with water.
How long do whales live?
There is evidence that the life expectancy of blue whales is 85-95 years.
What do they eat?
Their diet consists of different foods, depending on where they live. During the summer, the Blue Whale is capable of absorbing up to 3 tons of food daily. The blue whale is a baleen whale, i.e. They have no teeth, but they have whiskers, with the help of which the whale filters the water taken into its mouth, retaining food.
To watch whales you must go to the pyramids. Travel companies offer a full tour with translation from Madryn. The midday tour includes transfer and sightseeing. The full day tour includes a tour of the rest of the Valdez Peninsula, visiting the wolf and elephant seals, and bird sanctuaries.
The sightseeing tour consists of a boat ride to get close to the animals. Don't touch them or get too close to them. In any case, it's an imposition to stay at sea with these giants. The blue whale is the largest mammal in the world and the largest animal ever known. These whales breathe air, but they have their home in the water, which helps them support the weight of their huge bodies. We can find these mammals anywhere in almost any ocean, swimming in small groups or alone.
Keith in everyday life.
The usual speed at which a blue whale moves is approximately 25 km/h, but in case of danger the whale can easily reach up to 50 km/h.
They obtain food mainly at a depth of no more than 100 meters.
Blue whales live mainly in small schools of two or three whales. But there have been cases when whales gather in groups of up to 50 individuals.
Females of this species give birth to their young once every few years. To do this, they try to swim closer to the equator, into warm water. The size of the whale at the time of birth is about 5-6 meters in length. At first, the cubs feed on breast milk for the first 7 months; during these months, the cub is able to gain 90 kilograms in weight every day. They are quite independent, so female whales obviously have no questions about how to get them to eat or how to potty train them.
Sounds made by blue whales.
As you know, blue whales are capable of making regularly repeated sounds lasting about 25 seconds. But there have also been cases of whales making sounds lasting up to 60 minutes, and for several days. People cannot hear most of the sounds made by whales without certain equipment. For what purpose whales make sounds is not yet known to science, but it has been established that these sounds can be heard by their relatives at a distance of up to 1130 kilometers.
Do whales have enemies?
Due to its gigantic size, the blue whale has no enemies. However, there is one exception - a person. In the 20th century, blue whales were on the verge of extinction. Unfortunately, people, without thinking about the consequences, exterminate various animals; they also often subject animals to various abuses, such as dog fighting.
What is the population of blue whales?
Scientists are very closely monitoring these inhabitants of the world's oceans. There is information that at the moment, in all the oceans of the world, the number of blue whales is about 10 thousand individuals.
By the way, speaking about the truly gigantic size of these oceanic giants, we can give the following example - the largest whale is able to comfortably accommodate a football team of 11 people in its mouth.
