The bat is a magical species, and it is known as the world's number one "poison king". It has a strong ability to fly, and is also a natural host for a variety of zoonotic viruses, capable of carrying 10 viruses, and is the only mammal that has evolved the ability to fly. Although bats carry many zoonotic diseases, they are almost infected.
The host of the new coronavirus that swept the country this time is also bats. It is not only the host of the novel coronavirus, but also the SARS virus, Ebola virus, Marburg virus, Nipah virus, and MERS virus. <>
1.Bats are pterocods, and pterocods are the second largest group after rodents. Bats are mammals that are truly capable of flying.
The bat is very widespread and can be seen everywhere except in the north and south. Bats are social animals, and it is often possible for a single cave to be inhabited by millions of bats. Under this high-density contact, the virus spreads rapidly from bat to bat, and the surviving bats become resistant to the virus so that it can be transmitted to other animals.
2.Bats are ancient animal mammals that have evolved over 5 million years to become invulnerable. Although they can carry many viruses, they are almost uninfected.
3.The body temperature of bats is often maintained to around 40 degrees. For us humans, the immune system is fully turned on only when there is a fever.
In the daily life of bats, they are always in a state of fever. Such a high body temperature can inhibit the replication of the virus, reduce the number of viruses in the body, and speed up the body's immune response. The virus is getting stronger and harder to deal with in this state of heat.
4.The immune system of bats is different in that it does not completely kill the virus, but rather seeks to live peacefully with it. The virus does not cause any harm to bats, but bats can continue to excrete toxins on their own. <>
As long as we humans don't come into contact with them and don't eat them, it won't hurt us. Protect wild animals, they don't belong on our human table.
-
Bats carry more than 4,100 viruses, including more than 500 coronaviruses. Bats are like a mobile reservoir of viruses that include some viruses like Ebola, Marburg, Nipah and Hendra that are defenseless, so bats are really scary.
-
Bats carry not only coronaviruses, but also Ebola virus, hantavirus, rabies virus, henniper virus and other viruses, and are veritable "poison kings".
-
He is a mammalian like us humans, but he is the only mammal that can fly, he has a completely different routine from ours and lives in a dark and damp place. But she was covered in viruses, and the previous SARS virus and Ebola virus were all discovered from him, so to speak, a reservoir of viruses.
-
So far, 173 viruses have been detected in bats through various methods, of which 61 are zoonotic, and it can be said that in recent years, some new virus outbreaks and the return of old viruses are closely related to bats.

Bat is a Silurian animal, Silurian squire is second only to rodents, is the only one that has truly evolved with the ability to fly mammals, now there are 19 families, 185 genera and 961 species, except for the north and south poles and the ocean is too remote desert islands, all kinds of terrestrial ecological environments on the earth are used for it. Most bats rest during the day and forage for food at night. As a creature that evolved at the top of the pyramid, the bat can perform echolocation like radar, and its wings are made up of a thin layer of muscle and elastic tissue, covered by **.
There are many small blood vessels on the wings, because flight requires a lot of energy, the body temperature rises rapidly, and the small blood vessels on the wings have extensive contact with the air and can cool down, although this membrane can be easily torn apart, so many bats often have holes in their wings. But this does not prevent them from flying, because there are other ways in which the membrane helps them to fly, and the membrane can recover very quickly, and on the membrane of the bat, on the membrane of the bat, there are thousands of hairs that are invisible to the naked eye.
These hairs are connected to delicate sensing cells at the roots, making up thousands of flight sensors. In this way, the speed and direction of the air flow can be accurately sensed, so that the flight status, agitation frequency, shape and size can be controlled for a more stable and efficient flight. The bat's bone claw structure can drift 180 degrees in the air, sensing cells on the wing feathers can calculate wind resistance, and iron oxide in the brain acts as a built-in compass for geomagnetic navigation, which can navigate by sensing the magnitude and direction of the magnetic field, and can find its way home even if it migrates 2,000 kilometers.
The heart structure of the bat is very powerful for flight, and it can beat from 10 to 800 beats per minute. What makes bats so venomous is that they are the only mammals that can fly.
Flying requires a lot of energy, so bats have a fast metabolism. Why do animals have long and short lifespans? That's because different animals have different metabolic rates, and the faster the metabolism, the shorter and slower the lifespan.
This happens because the faster your metabolism, the more likely you are to lose DNA. But no, bats have evolved the superpower of DNA repair. This ensures that cell renewal can't go wrong and also makes bats surprisingly long-lived, with an average lifespan of up to 30 years, much longer than similarly sized mammals!
This is also characteristic of bats.
-
The reason why bats have so many viruses all over their bodies has nothing to do with their flight. The main reason is that the body temperature of the bat is very high, and it has a lot of antibodies to the virus, so Hong can carry so many sick and poisonous Hu types.
-
I think it has something to do with flying, because he is vulnerable to danger during the flight, and if he is not so poisonous, he is likely to kill himself.
-
It has something to do with flying, because bats have to fly for a long time and have a big ridge. The metabolism of bats is very fast, so the toxins in the body can bring energy to bats.

<> "Bats are the only kind of mammals that have evolved to truly fly, and they are always associated with horror and hideousness in people's impressions, and often appear as bloodsucking and cannibalism in some literature, film and television works, causing people to have disgusted emotions and feelings about it, let's take a look at whether bats are poisonous or not!
Are bats poisonous?
Bats are not poisonous, but bats do carry at least 14 viruses that can infect humans or animals, including rabies, Hendra virus, Nipah virus, "Hanta" virus, etc., especially Nipah virus, more than 50% of infected people will die and be discredited. Bats carry the virus, and in recent years there have been confirmed at least two outbreaks of sudden infectious diseases, one in Australia, where the Hendra virus was transmitted from bats to horses and then to humans. Another time was in Malaysia, where the Nipah virus was transmitted from bats to pigs and then to humans.
What do bats eat?
Bats have a wide range of diets, including fruits, fish, pollen and even blood, some species like nectar and fruits, some absolutely like to eat fish, frogs, insects, some species suck animal blood, and some species even eat other bats. In general, large bats generally feed on fruits or nectar, while most small bats mainly prey on insects.
Are bats harmful?
Bats prey on a large number of pests, which are beneficial to people and deserve protection. Bats are good at flying in the air, and play a very important role in maintaining the ecological balance of nature, all kinds of insectivorous bats can eliminate a large number of mosquitoes, noctuidas, beetles, nuns and other pests, and can prey on more than 3,000 in one night, which is beneficial to humans. Moreover, the manure collected by bats is also a good fertilizer and useful for agricultural production.
At the same time, processed bat feces is a type of traditional Chinese medicine and is known as "luminous sand".

Its flight characteristics lead to an ultra-high metabolic rate, and it has a fever of 40 degrees every day, and it is on people's bodies, and they have already burned to the point of retardation, but they don't, like no one has passed five million years. Bats carry more than 170 viruses, many of which can be indirectly transmitted to humans, and bats are the only mammals in the world with the ability to fly.
-
Bats and dinosaurs appeared in the same era, and it is said that many mammals lived in trees in the beginning, so the limbs of bats evolved into "wings" that could fly, and bats and flying dinosaurs are close relatives.
-
Bats belonged to reptiles a long time ago, and they grew wings in evolution, and they are called bats, and some people say that they belong to the rodent class, which is not correct, so bats were bats at the earliest, but they have evolved.
-
The bat, known as the Poison King, is believed to have evolved from rats eating salt. But in fact, they have no close relatives other than looking alike, and the origin of bats may be small insectivorous animals in ancient times.
-
Bats share a common ancestor with all mammals on Earth. Bats carry more than 100 viruses, and bats are the only mammals that can fly, making many wild animals intermediate hosts for viruses.
-
Bats have been on Earth for 80 million years and evolved from mammals such as horses and dogs.
-
Bats, like dinosaurs, are creatures of ancient times and have survived until now, and the bat may have been originally a flying bird, but due to changes in its living environment, it has constantly adapted to changes in its environment.

Now we are threatened by the boiling novel coronavirus, and we can only stay at home every day for our own safety and the safety of others, and all this is ** a creature, which is the bat.
In the past, most of us didn't know about bats, but now we know this creature very thoroughly, this creature called "Poison King", which carries more than 100 kinds of viruses in its body, and is a real "reservoir" of highly pathogenic viruses.
And in addition to the "poison king" bat, what other natural host carriers of famous viruses?
I think a lot of people think of the civet cat. That's right, it was this creature that brought us SARS in 2003.
More than 10 years later, we who have experienced SARS still remember it vividly, and to this day"sars"It's still a frightening word.
It quietly emerged in the winter of 2002 and broke out in the spring of 2003, "highly contagious, spreading quickly and with a high mortality rate". With the flow of infected people, it spread to all parts of the country and even around the world, and 24 provinces (autonomous regions and municipalities) in Chinese mainland have reported SARS cases.
For the first time ever, the World Health Organization has issued global travel advice for people to travel with caution. The disease is known as severe acute respiratory syndrome, or SARS for short. The outbreak lasted 8 months and swept through 26 countries, infecting 8,096 people and killing 774.
Among them, China reported 7,429 cases and 685 deaths.
All of this is caused by the virus carried by this seemingly harmless creature of humans and animals.
In addition to the above creatures, there is also a creature called wild marmot, which contains the plague bacillus, the culprit of the plague.
Nowadays we rarely hear the news of plague, thinking that the disease has disappeared, but in fact it is not, plague is a "natural epidemic" disease, and the animals carrying plague bacteria are mainly rats, marmots and other animals. In other words,Even if there was no plague in humans, the disease would not go away, but would continue to spread among rodents and other mammals, and rodents would also get sick, but the threat of plague would not be as severe as that of humans.
But now we don't need to worry about dying of the plague, and now the disease is mature and can be controlled.
These are some of the information I have found for you, I hope it can help you.

Civets also have a lot of bacteria on them. SARS in 2003 was caused by bats coming into contact with civet cats and people eating civets. Therefore, human beings should not infringe on small animals, but live in peace with nature!
-
Wild animals civet cats and bamboo rats, as well as wild snakes, are natural reservoirs for many viruses, and most wild animals carry many viruses.
-
There are many of them, such as wild snakes, wild hedgehogs, wild rabbits, which contain many viruses that humans cannot resist, as well as civet cats and other animals that can be used as hosts for virus transmission.

The civet cats, monkeys, bamboo pheasants, wild snakes, hedgehogs, pheasants, hares, wild boars, etc., which once caused SARS.
The frequency of ultrasound emitted by bats ranges from 20 to 120 kilohertz. The frequency of ultrasound emitted by different species of bats is different and some are very similar, which is related to the size of the object they forage, so it is difficult to distinguish species by frequency. The ultrasound frequency of bats in Taiwan also varies greatly, and it is known that the ultrasound frequency of the small hoofed bat in Taiwan is the highest (about 115-120 kHz). >>>More
