Which animal has the biggest heart? Giraffe - the biggest heart in the world
The internal organs of a glass frog, including its heart
Of course, the human heart is an amazing miracle thanks to which we live, it is the vessel of the soul, and so on. However, is it capable of self-healing? Does it pump exclusively pure blood? Is it possible to freeze it and then bring it back to life?
The hearts of some animal species are capable of this and more. We've scoured the animal kingdom from the depths of the ocean to the summit of the Himalayas for the wonders of the heart, and here's what we found.
Insects
The insides of an earthworm, including its five pseudo-hearts
Earthworm
Depending on your point of view, earthworms either have five "hearts" or no heart at all. Although they do not have the usual multi-chambered muscular organ, they do have five special blood vessels called “aortic arches.” By contracting, the aortic arches pump blood throughout the body of the worm. So if you accidentally damage an earthworm's heart, don't worry - it has four more just like it.
Cockroach
The human heart consists of four chambers, each of which performs a specific function - if something happens to one of them, something irreparable will happen. In turn, the cockroach's heart has twelve to thirteen chambers, which are arranged in a row and driven by a separate group of muscles. This means that if one chamber stops functioning, nothing will happen to the cockroach.
Hoverfly
Hoverfly
Hover flies love to hover in the air above flowers, collecting precious pollen. What helps them do this is essentially the heart, which pumps blood to the head and chest, where the mouthparts and muscles responsible for flapping their wings are located.
Pisces and their neighbors
Danio rerio
This beautiful little fish contains the heart of a real superhero. In 2002, scientists found that if up to 20% of the lower ventricle is removed from a zebrafish, the fish can restore the lost tissue within two months. This occurs thanks to specialized muscle cells that are capable of not only regeneration, but also stimulating the growth of new blood vessels. Having studied the self-healing hearts of zebrafish, scientists hope to apply their knowledge to human organs.
Spiny-nosed Whiteblood
Spiny-nosed Whiteblood
The spiny-nosed whiteblood lives in the Southern Ocean at a depth of one kilometer. How does she cope with the cold? Partly thanks to its heart, which is much larger and about five times stronger than the heart of an ordinary aquarium fish. The blood of the spiny-nosed whiteblood also lacks hemoglobin, a red protein responsible for binding oxygen. Instead, thanks to low temperatures, oxygen dissolves directly into the spiny-nosed whiteblood's plasma, which causes its blood to become transparent.
Anatomy of cuttlefish
Cuttlefish
Like all cephalopods, the cuttlefish has three hearts - one heart for a pair of gills and one heart for the rest of the body. Research results show that cuttlefish living in cold waters have larger heart sizes than those living in warm waters; this is associated with increased aerobic capacity. In addition, their blood contains hemocyanin (instead of hemoglobin), which gives it a blue color. Cuttlefish are true aristocrats.
Birds
Hummingbird captured in flight
You've probably heard that hummingbirds beat their wings 15 times in one second - all thanks to their unique heart, which beats up to 21 times per second and ensures rapid delivery of oxygen to muscle mitochondria.
mountain goose
Migration is not an easy process for all birds, but bar-headed geese are the least fortunate in this regard: their route runs directly over the Himalayas. These birds regularly fly over mountain passes at an altitude of 6,000 meters above sea level - and all thanks to the fact that they have an unusually strong heart, connected to the muscles that are used in flight, a set of additional capillaries.
Emperor penguins
Emperor penguins are famous for their soft hearts. Emperor penguin pairs spend most of their time caring for each other and their offspring. Less known, but very important, is the fact that the hearts of emperor penguins work extremely slowly, especially when immersed in water: they beat about 15 times per minute, cutting off blood supply to all (except vital) organs and providing the body with just that much oxygen , which is necessary for deep-sea hunting.
Reptiles and amphibians
wood frog
The hearts of many animals, from bears to marmots, slow down when they hibernate, but for all we know, wood frogs' hearts may stop beating altogether during this period. In winter, these frogs essentially turn into “icicles”: thanks to a special solution in their cells, they can suspend metabolic activity and allow most of the water in their bodies to solidify without any consequences. Their hearts take it for granted; they stop beating when the world freezes and resume activity when it warms up.
Glass frog
All frogs have a three-chambered heart with two atria that receive blood from other parts of the body and one ventricle that shunts it back. Glass frogs are unique in that you can observe this entire process with your own eyes - their translucent skin on the belly allows a person to see the work of the heart and blood vessels inside these amphibians.
Python lies in wait for its prey
Python
After a python has had a good meal, its heart increases in size by 40 percent due to fatty acids supplied with food. (This speeds up digestion, a process that can take up to several days for pythons.)
Mammals
The heart of a blue whale, which is kept at the Royal Ontario Museum
Blue whale
Popular legend has it that the blue whale's heart is the size of a car, and a person can easily fit through its aorta. This is not entirely true. According to Jacqueline Miller, the blue whale's heart is the size of "a small golf cart or an electric circus bumper car," and its aorta can only fit one human head.
Giraffe
The giraffe's heart must fight against the pressure of gravity every day to deliver blood to the long-necked animal's head. It manages to do this thanks to very thick and durable walls and blood vessels that expand and contract at a rapid pace. As the giraffe's neck lengthens, the blood vessels also undergo changes, becoming thicker.
Cheetah
A cheetah's resting heart beats about 120 times per minute - about the same as the heart of a human jogging. While a human's maximum heart rate is approximately 220 beats per minute—and takes some time to reach—the cheetah's "heart rocket" can reach 250 beats per minute in just a few seconds. This change is so intense that it allows the cheetah to run at top speed for only about 20 seconds before the predator's organs begin to overheat and become damaged.
Which animal has the biggest heart?
- At the whale's
- At the Blue Whale. the heart weighs 500-700 kg
- in birds, compared to the size of the animal itself...
- A giraffe's heart is huge. It weighs 11 kilograms, has a length of 60 centimeters and walls 6 centimeters thick.
The giraffe's heart has one peculiarity: it has additional valves, which sometimes close and reduce the blood pressure in one of the organs of its body several times. This happens when the giraffe needs to tilt its head (for example, at a watering hole, or behind the grass), because otherwise an instant rush of blood under strong pressure can rupture the blood vessels of the brain. - A giraffe's heart is huge.

This happens when the giraffe needs to tilt its head (for example, at a watering hole, or behind the grass), because otherwise an instant rush of blood under strong pressure can rupture the blood vessels of the brain.
The giraffe is the tallest living mammal: its height from the ground to the forehead reaches 4.85.8 m; blood must be transported from the heart to the brain to the same height. The pressure created by the heart required for this is 300 mmHg. Art. Compared to humans, giraffes have twice the amount of red blood cells. The giraffe's heart passes about 60 liters (!) of blood per minute.
A horse has 18 more bones than a human. Giraffes have the largest heart and the highest blood pressure of any land animal. Giraffes have a completely black tongue, the length of which can reach up to 45 cm.
But on another site they write something else. The blue whale has the largest heart, more than 500 kilograms. There are whales whose hearts weigh 700 kilograms. The whale also has a very large tongue of 5 tons and a liver that weighs 3.5 tons. These organ sizes are the largest on our planet.
Heart of caress
The answer to the question of which animal has the biggest heart is quite simple. Of course, on land it is a giraffe, and in the ocean it is a blue whale. The mass of their hearts is 8.4 and 9.5 kg, respectively.
But if you calculate the ratio of the mass of an animal’s heart to its body mass, then these animals will not take first place. Studies have shown that the largest heart in relation to the body weight of the animal has a rather small, well-known animal - the weasel. In a small predator, the heart accounts for 6.7% of the total body weight, while in the blue whale it is only 2.5%, and in the giraffe it is even less, only 0.5%.
Appearance of weasel
Weasel is the smallest predator on earth. The color of the weasel resembles an ermine, the body is thin and flexible with short legs. The fur of the animal is not long and at the same time fits tightly to the body. Color depends on seasonality. In winter, the predator has a white color, this helps it hide in the snow. In summer, brown-brown on the outside of the legs, on the tail, on the top of the head, back, and on the sides. The chest, belly, paws on the inside, throat and the edge above the upper lip still remain white. The thickness of the weasel's fur is always the same - both in summer and in winter, the only difference is that in winter the hair becomes thicker and a little longer. The weasel has a short, blunt nose and small semicircular ears.
The animal lives in forests and fields, but can also settle near humans. Most often, the weasel settles in burrows, hollows or under stones, lining its home with moss and dry grass. This species is quite widespread. The habitat of this animal covers very large territories, including China, North. America, Japan, Australia, Korean Peninsula, Mongolia, Iran, Afghanistan, Iraq (northern part of the country), Algeria, Asia Minor, Europe, Egypt, Morocco. That is, this predatory mammal is found in almost all corners of the planet. But the greatest distribution of weasels is observed in Europe, Northern Asia and North America.
Weasel lifestyle
The weasel's diet is quite varied; its diet includes mice, frogs, small rabbits, copperheads, moles, hamsters and small chickens. She hunts mainly at night, but if no one bothers her, she can get food during the day. In spring, weasels begin their mating season. Pregnancy lasts 5 weeks, after which 3 to 7 cubs are born. Weasel is a caring mother, constantly takes care of and protects her offspring and, in case of danger, carries them to another place in her teeth (like domestic cats).
The lifespan of this predator is about 20 years. To maintain body temperature, animals must constantly eat; per day, weasels eat up to 1/4 of their body weight. There is a popular belief that where the weasel settles, there will never be mice. An adult male of this species can even kill a hare or black grouse. Some weasels living in the barn have gotten used to climbing onto the back of a horse and, biting its scruff, licks the horse's blood. This is why many horses are horrified when they smell this beast in the stable.
Weasel hunting
Most often, weasels are hunted by large predators such as foxes and sables, and hawks and owls are also considered enemies of this animal. But, despite this, the weasel can provide worthy resistance to these predators. There is a known case when a weasel caught by a hawk in flight was able to gnaw off the throat of its offender. People practically do not hunt weasel, since fishing for it is impractical. True, sometimes when catching other fur-bearing animals, weasels are also caught in snares. In fact, this animal brings more benefit by exterminating mice in agricultural areas and thereby regulating their numbers.
How amazingly nature works, a rather small animal has such a big heart. And, conversely, in huge representatives of flora and fauna, the heart mass to body mass index is very small.

The number of deaths from fighting in Donbass has been announced
The armed conflict in certain areas of the Donetsk and Lugansk regions has been ongoing since April 2014. Deputy Speaker of the Verkhovna Rada Irina Gerashchenko announced new figures on how many Ukrainian citizens died in the fighting in Donbass.
Peacekeepers in eastern Ukraine are becoming a reality
Stepan Poltorak expressed optimism regarding the introduction of peacekeeping troops into the territory of certain areas of the Donetsk and Lugansk regions. As the Minister of Defense noted, the issue of introducing peacekeepers to the east of the country is becoming increasingly relevant and real. In addition, some countries have expressed a desire to help Kyiv finally bring peace to the eastern regions of Ukraine.
Volker clarified the date of elections in Donbass
The representative of the American establishment on the Ukrainian issue, Kurt Volker, commented on the topic of the possible date of the upcoming elections in Donbass. It is noted that they must take place only in accordance with Ukrainian legislation. The full deployment of peacekeeping forces will prepare regions temporarily outside the control of the central government for a transparent and democratic expression of will.
OSCE criticized ATO forces
The Organization for Security and Cooperation in Europe criticized the Anti-Terrorist Operation forces, which advanced into the so-called “grey zone” and regained control over several populated areas. The special monitoring mission notes: the Ukrainian military group has moved several hundred meters, and therefore such a step could provoke an escalation of the conflict.
The OSCE recorded a violation of the Minsk agreements
The Organization for Security and Cooperation in Europe continues to record violations of the Minsk agreements in certain areas of the Donetsk and Lugansk regions. Observers note that the parties began to bring up heavy weapons, which equates to gross violations of Minsk-2, signed by the parties in February 2015.
Kuchma told how to end the conflict in Donbass
The armed conflict in certain areas of the Donetsk and Lugansk regions can be stopped if the United States uses its full geopolitical weight. This was stated at the Baltic-Black Sea Forum by the second President of Ukraine Leonid Kuchma. In particular, he added that the countries of the European Union have been playing with the Russian aggressor for too long and have clearly forgotten the events of the thirties of the twentieth century.

Animals have the biggest heart
Today there is still a lot that remains unsolved not only in the world of plants, but also of animals. All species have not yet been fully studied. But scientists have already achieved considerable success and found out which animal, for example, has the largest heart - the blue whale. Its gigantic size can be compared with the largest ship. After all, the weight of the animal is about tons, and the heart weighs about 600 kilograms. Today, the blue whale is the largest giant of all representatives of the animal world. It’s hard to imagine how much food he needs for the whole day to be full. But they are the way nature intended them to be, so blue whales feel quite comfortable in the depths of the sea, feeding on plankton. Its lightness, due to its size (about 3 thousand liters), allows it to stay at sea depth for more than 20 minutes.
But, unfortunately, in the second half of the twentieth century. Their numbers began to decline due to increased poaching and their uncontrolled extermination. But this species is under the control of conservationists, as one of the rare and endangered inhabitants of the planet.
Today, the blue whale occupies a leading place among other animals in terms of not only its external, but also its internal dimensions!

Which animal has the biggest heart?
Which animal has the biggest heart, the highest blood pressure and a black tongue?
Listen. far away on Lake Chad
An exquisite giraffe wanders.
And he needs to maintain an incredible 340/230 pressure of the circulatory system, so that at the very edge of his long neck, at a height of more than five meters from the ground, a small brain works and a giant (up to half a meter), DARK (not black) tongue moves.
What maintains pressure in the circulatory system? That's right, a twelve-kilogram heart.
It's so elementary!
don't be ridiculous, or clarify the question. If it's on the ground, yes, but it says an animal there, and not among the terrestrial ones :) - 5 years ago
It is quite natural that the largest animal should have the largest heart. After all, the heart is a kind of blood pump that supplies blood to the entire body.
Based on all of the above, I would venture to suggest that the blue whale still has the largest heart among animals.
But this applies to all animals, and if we take animals living on land, then this is the giraffe. But among all animals it is only in second place after the blue whale.
Regarding the black tongue and blood pressure, these parameters are also suitable for the giraffe.
Maybe I will upset someone, but the blue whale has the biggest heart on planet Earth.
But the blue whale is not a land animal. If we look for the largest heart in an animal that lives on land, then of course we will find it in a giraffe (although my brain immediately, as soon as I read the question, answered - an elephant. But no!).
And the giraffe has the highest blood pressure, yes. After all, so much needs to be done to deliver blood to the brain, just imagine how long it takes for the blood to get up the neck.
And the giraffe also has a black tongue:
The giraffe has the largest heart, black tongue and the highest blood pressure (300 mm Hg).
The heart is large, it has additional valves, and it also needs to create more blood pressure than other animals. The blood must rise to great heights to fuel the giraffe's brain.
For me, this animal is remarkable for the color of its tongue - it is black, and is also capable of stretching 45 centimeters to reach the twig it likes.
This animal simply needs a large heart in order to be able to pump blood from the lower extremities, along the long neck, to the head and back.
I met different levels of pressure, but one thing can be said for sure: his levels are three times higher than human levels.
GIRAFFE has the biggest heart.
This is probably a giraffe. Its heart is huge (11 kg, length 60 cm, wall thickness 6 cm). The heart has an additional valve to reduce blood pressure in one of the giraffe's body organs. When tilting the head (drinking water, nibbling grass), blood vessels in the brain may rupture. To transport blood from the heart to the brain, the pressure created by the large heart is necessary.
If we take it from animals, then the biggest heart belongs to the giraffe. And this heart pumps the highest pressure. And the tongue is dark in color, almost black.
Often many people confuse and argue, saying that the whale has the biggest heart, but we have a question about animals, and a whale is a mammal. So it does not participate in the ranking.
This animal lives in Africa and it is a GIRAFFE. Because of its long neck and height, the giraffe's heart has to pump blood intensively to get it to its head. The giraffe also has the highest blood pressure of all fauna on planet Earth.
Interesting question. I would answer blue whale if it’s a riddle))
If you don’t need to take into account the proportion relative to the body, I think it’s a blue whale, maybe a sperm whale.
When I first saw “the biggest heart of an animal,” I immediately rushed to write about the blue whale, whose heart weighs almost a ton and whose highest pulse is twenty beats per minute. The blue whale actually has the biggest heart of all animals.
But then I read the explanation to the question and decided that we were talking only about terrestrial animals. And among land animals, the owner of the largest heart is the tall, handsome giraffe. The heart of an adult is at least half a meter long and weighs eleven to twelve kilograms. And in order to pump 60 liters of blood per minute throughout the body, especially to a height of five to six meters (that’s how long his neck can be), the heart has to create a pressure of 300 mm Hg. Art.!
I would assume that this is an elephant (there is no need to argue that it is big), but it turns out that another animal has the biggest heart.
This is a giraffe, in addition to a big heart, it also has high blood pressure. This is because the heart has to pump blood up the animal's long neck.
And the giraffe’s tongue is really black, and it’s also the longest.
Who has the biggest heart
When they want to emphasize the generosity and kindness of a person, they say that he has a big heart. But, if we take this expression literally, then not a single person can compete with whales. It is known that the truly largest heart beats in the chest of the blue whale, which is also the largest mammal on Earth. If we open and read the Guinness Book of Records, then in the section where it talks about whales, there is a signature in small print that says that the heart of a female blue whale can reach 698.5 kilograms.
If we compare this mass with what is closer to a person, then it will be equal to the mass of a passenger car, or the weight of ten men at once. The size of the whale’s main artery, the aorta, is also impressive. If we compare it with the world's largest water pipe, which is located in London, then the latter will be inferior to the whale aorta both in diameter and in water pressure.
The largest heart in nature is also one of the slowest. In a whale, the frequency of its contractions is only 9 times per minute (compared to a minute in humans). But it works very loudly. When a whale opens its mouth to swallow food, the sounds caused by its heartbeat travel over quite large distances. They can be clearly heard in special acoustic devices that are used by sailors.
But the records of the largest heart on earth do not end there. It turns out that it is the most reliable, wear-resistant and highly efficient pump known to mankind. Not a single designer has yet been able to reproduce the “technique” developed by nature many millennia ago, although attempts are constantly being made.

Research results show that cuttlefish living in cold waters have larger heart sizes than those living in warm waters; this is associated with increased aerobic capacity. In addition, their blood contains hemocyanin (instead of hemoglobin), which gives it a blue color. Cuttlefish are true aristocrats.

While a human's maximum heart rate is approximately 220 beats per minute—and takes some time to reach—the cheetah's "heart rocket" can reach 250 beats per minute in just a few seconds. This change is so intense that it allows the cheetah to run at top speed for only about 20 seconds before the predator's organs begin to overheat and become damaged.
Even if we take into account the giants that inhabited the Earth millions of years ago - brachiosaurs, blue whales still surpass them in size, weighing more than 2 times the weight of these fossil animals. If we compare the blue whale with the second largest modern animal living on the planet, then the superiority of the whale is undeniable - it is 38 times heavier than the elephant. The average length of a blue whale is 26 meters, and the largest whale ever seen by man reached a length of 33.5 meters. On average, such a whale weighs 150 tons, approximately the same as 2,400 people weigh.
With all this, the heart rate of the blue whale is the slowest of all animals - during a dive it is only 4 to 8 beats per minute. At this time, only the brain and the giant are supplied with blood. By the way, its heart weighs about 650 kg and is comparable in size to a small car like a Mini Cooper. The main aorta is larger in diameter than the world's largest water pipe, located in London, and can withstand greater pressure. And you can hear the heart of a whale very far away - at a distance of several tens of kilometers, these sounds are easily picked up by acoustic instruments located on ships. The heart of the whale is a reliable and wear-resistant pump with high efficiency; no designer has yet succeeded in bringing such technical solutions to life.
How blue whales live

Once upon a time, all oceans were inhabited by blue whales, but their numbers gradually decreased; in addition, whaling caused the fact that today the Arctic population of these animals numbers, according to various estimates, from several hundred to several thousand. A more accurate count is not possible given the deep-sea blue whales.
To feed itself, this giant needs to eat about 1 ton of krill every day - small crustaceans and shrimp that live in the surface waters of the ocean, which has an energy value of about 1 million calories. Swimming through layers rich in krill, whales swallow hundreds of tons of water and crustaceans, and then push out the water, filtering the krill through a sieve of “baleen” - numerous horny plates hanging from the roof of their mouth.
The whale's oral cavity is a spacious room with an area of about 24 square meters. m.
Whales migrate throughout the year - in the summer they “graze” in the subpolar regions of Antarctica, and by winter they move to warm equatorial waters, covering thousands of miles of travel. At the same time, “on the road” they may not eat anything at all, using up the fat reserves that they gained on summer or winter pastures. Whales usually travel alone, sometimes in pairs, and can communicate by emitting intense low-frequency sounds reaching a level of 188 dB, which allows their relatives, who are located at a distance of about 1,500 km, to hear them.
In a calm state, the whale swims at a speed of 10-15 km/h, but sometimes reaches speeds of up to 35-40 km/h, which, however, can be maintained for a very short time, only a few minutes.
Female whales carry their babies for 11 months, a 7-meter newborn “baby” weighing 2 tons is able to drink more than 0.5 tons of fatty mother’s milk daily and double its original weight in a week, by which time they can already provide themselves with food on their own . Whales become adults only after 4.5 years, and reach full physical maturity by 14-15 years.
