Why does the scientific community say that lions kill tigers?

First of all, in nature, tigers and lions don't meet. Lions are in Africa and tigers are in Asia. The fight between the lion and the tiger is man-made.

From a scientific point of view, the argument about who is stronger, the lion or the tiger, is biased, just as the lion represents the west and the tiger represents the east, and the west does not often regard the tiger as a villain. But the truth is below.

For a long time, the two big cats, the tiger and the lion, have been bothering many people who don't know the truth.

But now the scientific community, through authoritative national geography and so on. According to the census data, it has been generally accepted that tigers are better than lions. Here, the detailed data of tigers and lions are used to illustrate that all the listed data are average values.

1, body shape comparison

The tiger is the biggest cat, and there is no objection at present.

2. Physiological data

(1) skull comparison

Because of the mane, the lion feels quite big visually. In fact, after removing the mane, it is similar to a tiger. After peeling, it is difficult to distinguish liger, so the skull is not very different. The skull of a tiger is slightly larger than that of a lion.

The mane is a symbol of the lion, which is often infinitely exaggerated and even becomes a decisive weapon. In biology, the role of male mane is defined as: the display of strength between male lions, the criteria for female lions to choose a mate,

The mane has a certain defensive effect on the lion, but it also weakens its attack ability.

2) Heart volume

Anatomically, the heart capacity of a tiger is larger than that of an African lion, which is quite important. Among opponents with the same physical quality, it shows that a species has greater explosive power, endurance and physical recovery ability.

(3) mouth

The opening and closing degrees of the tiger's mouth and the lion's mouth are all around 1 10 degrees.

Tiger jaw spherical muscle is the most developed in cats, with little difference in liger bite force, but it is slightly stronger in tigers, about 450kg in tigers and 400kg in lions (attached: the back end of crocodile is about1000 kg (2,200 kg), the front end is about 770kg, the great white shark is about 770kg, and the human is about 80kg).

The tooth length of tiger and dog is about 6cm, that of male lion is about 5cm, the biting depth of tiger is about 1 1cm, and that of male lion is about 9cm. The bite depth of 1cm can often determine whether the other person is alive or dead, which also makes the lion's prey mortality rate far less than that of the tiger.

(4) forelimbs

Tiger Claw is the largest of the cats. The claw width of male tiger is about10.5-11.5 cm, that of female tiger is about 8.5-9.5cm and that of male lion is about 7.5cm.

Comparison of the soles of tigers and lions of the same age;

Clapping hands is a common technique used by tigers, and the palm strength is the highest among cats, which can reach 1 ton. The palm strength of a tiger is about twice that of a lion. Physical strength is 20% greater than that of a lion, and no matter whether the lion fights or preys, flapping is not its characteristic.

All cats have the habit of grinding their claws, but the frequency of lions grinding their claws has decreased in adulthood, which is related to their living environment, so their claws are not as sharp as tigers.

Tiger Claw is the longest of the cats, with a tiger about 10cm, a tiger 9.2cm and a lion 8cm.

Lions are often thrown off by large prey, which shows that their forelimbs are not strong enough and their claws are not deeply embedded, so it is extremely difficult for tigers to be thrown off by bison.

(5) Hindlimb

Lions can only stand half upright.

Tigers can stand completely upright.

Tigers can also walk on only two legs.

A tiger can jump with only two legs. Then jump. These movements are beyond the reach of a lion. Why is there little difference in appearance between a tiger and a lion, but there is such a big gap in action?

Because: this is the difference between species. Lions are inferior to tigers in all indicators. However, nature also has a good side, so let lions live in groups to make up for these shortcomings. Lions live in groups successfully, which is also their successful choice.

The strength of hind limbs directly affects the jumping ability. Tigers can jump to a height of 2-3m, females are about 1.8m, tigers can reach a height of 6.5m, females are 4.5m, and males can hardly jump.

Tiger's limbs are thicker, while lion's limbs are much thinner and thinner.

From right to left are Siberian male tiger, Bangladeshi male tiger and African male lion.

6) Muscles

Hu Meng and lions belong to the tropics and subtropics, and their muscles are similar. The tiger's shoulders are very strong, and the lion's strength is concentrated on his neck.

The fat of Siberian tiger is mainly under the skin, not attached to the muscle, and the muscle weight can account for about 80% of the whole body weight. According to the anatomical report of China biologists on the Northeast Tiger, the muscle fibers of the West Tiger are extremely thick, and almost no fat can be found, which is stronger than the muscles of the best bodybuilders.

The female Siberian tiger is with the African lion and the lioness.

7) bones

Tigers have more perfect bones, and the average bone density is about 1.2% higher than that of lions, which means that tigers are stronger and more resistant to fighting. So lions are often seen kicked by zebras and bison, and tigers are rarely seen kicked by bison.

Description: The lion's skull is at the top right, and the tiger's skull is in the middle. Obviously, the tiger's skull is wider, while the lion's skull is longer and narrower. From these two skulls, it can be reflected that the tiger's vision is better and the lion's mouth is longer and thicker (relatively speaking). This is mainly because the lion's nasal cavity is bigger, and it may have a better sense of smell. The distance from the top of the tiger's skull to the chin is slightly shorter than that of the lion, and the distance on both sides of the skull is obviously wider than that of the lion, while the back of the brain occupies nearly half of the space, and the relative capacity of the brain is obviously larger, which is of great help to the improvement of IQ. Generally speaking, the skull of a tiger is slightly larger than that of a lion, giving people a sense of structural balance and a strong sense of beauty.

From top to bottom on the left: cheetah, puma, snow leopard, jaguar and Far East leopard.

From left to right: domestic cat, bobcat, Canadian lynx, Karakal, clouded leopard. 8) Speed

The tiger's sprint speed is about 80km/h, the female lion is between 64km/h and the male lion is 56 m/h.

Authoritative national geographic data map.

Tigers travel 50 miles an hour in the snow. 1 mile = 1 609.344 meters, which is 80.465 kilometers when converted into kilometers.

9) Flexibility

Tigers are slender, while lions are short, which means tigers can make wider and smarter turns.

10) Other

In terms of balance, tigers can walk on the balance beam of gymnastics, but lions can't.

Although the tiger's tail is not as powerful as the legend, it is still its attack weapon, and the lion's tail has no attack effect.

Cat watchers think that tigers are cunning and lions are straightforward.

The above is the comparison of physical hardware, and the following is the comparison of liger's life practice, which is actually the comparison of technical software.

Skills are very important to wild animals. Someone simulated a beast-beast duel before, but it was immediately regarded as a joke, because only the hardware data was entered, but the skill data was forgotten. Because according to this simulation, cheetahs won't catch impala and leopards won't catch zebras, because these prey are stronger than hunters, and zebras can kick leopards over with one foot, but the data shows that leopards won't escape, 100% will be kicked over. ...

In fact, the above physiological data have explained which is better or worse. Skill is more a subjective concept of human observation, while practice is often the application of physiology in life. Let's take this as a reference.

3. Living habits

(1) Some people say that lions live in groups, that is, lions are better than tigers. This kind of people are actually based on the real life of the lion, that is, the lion has a strong overall consciousness, but they ignore another fact, that is, only the strongest lion can decide the outcome in the same kind of struggle.

So, will the lion regard the tiger as the same kind? The answer is possible, because natural mating will occur between tigers and lions, and it will only happen if the other is regarded as the same kind in wild animals.

(2) Some people say that lions make a living by fighting, so he thinks that lions have a stronger desire to fight, but he doesn't know that tigers are extremely territorial. Little tigers will also fight big tigers who invade their territory, and tigers with home court advantage have stronger fighting power (because this is a rice bowl problem). On the contrary, in most cases, the lion only needs to shake his mane to decide the outcome of the battle. In zoos, tigers kill lions mostly because they think lions have invaded their territory, but in the wild, territorial disputes are common, especially when the number of tigers once flourished.

In other words, lions fight more for their spouses, while tigers fight more for their territory, and the fighting frequency of the two is almost the same.

(3) Females should not only fight for territory, but also fight for their cubs. All male cats have the habit of killing non-intimate kittens. A single female tiger often fights with a larger male tiger to protect her cubs, and a group of female lions surrender directly in this case. The tiger lives alone, and the tigress raises her cubs independently, which shows that the tiger's viability is quite strong, and the lioness cannot raise her cubs independently at all.

(4) Some people say that lions can't measure the strength of their opponents and go forward bravely. Actually this is a serious misunderstanding. Lions measure their opponents by their manes, and lions with poor manes will choose to retreat automatically. In the eyes of the lion, the tiger is a lion with a poor mane. Because the male tiger has no mane, the lion often thinks that the tiger is not as good as himself.

Tigers, like other cats, are very cautious because they live alone, and they will carefully evaluate their opponents' strength, because mistakes in evaluation will lead to serious injuries and they will not be able to hunt, which means that tigers will not fight uncertain wars, which leads to a problem, that is, fighting between lions and tigers is a beast that can win the battle in the eyes of tigers, and this evaluation is definitely more accurate than human evaluation.

4. Combat skills

Cats' bite force is not the biggest among all animals, but claws are the strongest and agility is the highest, so claws are the winning weapon, while teeth are just deadly weapons. With claws and skills, the cat is the only mammal among all animals that can defeat the beast stronger than itself independently (others can only rely on group strength).

(1) Tiger-fighting uses the palm-slapping method, which is actually a set of combination boxing. It relies more on skill, and rarely puts his head together early.

(2) Lions are the exception of cats, and the fight between them is actually bigger than whose mouth. Due to the lack of strength and skills of limbs, they almost gave up the advantages of cat claws and skills. Lions rely more on their own body and strength, which is a kind of pushing and shoving technology, but we know that lions will not have an advantage over tigers in both size and strength.

Tigers can hold their palms together, but lions can't fully support their weight because of the strength of their hind legs. In order to give full play to the power of the palm, they must support the ground with a forefoot.

(3) The mane has a certain protective effect on the lion's throat, but tigers often lock their throats with forelimb fights before gaining a considerable advantage, because it is irresponsible to lock their throats before gaining an advantage.

5. Hunting skills

Hunting skills can reflect the skills of wild animals from the side.

(1) The tiger's prey is usually a sneak attack, followed by a short sprint, which requires a stronger explosive force, because if the response is slow, the prey can easily escape, and long-distance pursuit is not the tiger's strong point. Tigers jump on the backs of buffalo and hug them tightly, even if they are larger adult Asian elephants, while lions can only jump on the backs of bison, which are not much smaller than African bison. Lions usually hunt in groups and mainly rely on the support of group strength to pounce on them.

(2) Lions bite their necks on smaller prey and noses on larger ones such as bison, but the way of choking by biting their noses often seems to be slow. Lions often have the possibility of letting their prey escape. In fact, five lions (including lions) killed a bison on TV and finally escaped, reflecting that lions can't kill their prey effectively and quickly, and even cheetahs with almost no fighting ability can escape after being seriously injured, reflecting the killing rate of lions.

The success rate of tiger killing is quite high, and the killing methods are more abundant, such as breaking the cervical vertebra, biting the throat and biting the neck. For smaller ones, the cervical vertebra is almost directly broken, and for bison weighing more than 200kg, the neck is bitten off, which is completely different from the tactics of lions against bison, but the killing efficiency is higher, and the prey is often fatal, because tigers can't afford such mistakes, especially Siberian tigers.

(3) Depending on the prey, the success rate of lions is between 10-20%, and that of tigers is about 5%. Although the success rate of lions is higher than that of tigers, it is very low on average. The food utilization rate is not as good as that of tigers, and they can only take care of one meal, while tigers often take care of them for a long time once they prey.

The lion is the only cat that eats scavengers, which reflects the success rate of a single lion.

(4) Both lions and tigers have the ability to kill oversized prey under unusual circumstances, such as lions against females and giraffes. There are also tigers for female elephants, bison and so on. But a single lion can't kill prey bigger than himself, which is actually rare in cats. It is estimated that only servcats are like this, but servcats can be regarded as the best among cats after all, and like cheetahs, they have to pay a small price for agility.

6. Survival competition

The main competitors of the lion's living environment are hyenas and leopards, not hyenas and leopards, but brown bears and Far Eastern leopards.

(1) The life of a single lion is extremely difficult. Generally, there are only three endings for a single lion to be driven away by a group of lions: starvation, being hunted by hyenas, and being murdered by a group of three-color jackals.

(2) The strength of a single jackal is not as good as that of a hyena, but the scale and toughness of a jackal group are far greater than that of a hyena group, and different jackal groups can even unite against Hu Meng. Nearly 60 jackals killed a female Hu Meng at a heavy price, which was a famous battle example, and it was composed of three different groups of jackals.

(3) The brown bear is a much bigger beast than the West Tiger. The Far East Leopard is extremely difficult to survive under the pressure of the West Tiger, but the leopard of the same species as the Far East Leopard is quite moist under the pressure of the lions. It can be seen that lions are far less able to stifle the development of leopards than tigers, so leopards are called the most successful big cats.

Therefore, the competitive environment between tigers and lions can be said to be equally dangerous, but even so, excluding human factors, tigers live alone very successfully, while lions live alone means death.

7. Examples of combat

Now we can see that liger Dou is kept in captivity, and we can't draw an accurate conclusion from it, but we can draw a reference conclusion.

(1) Compared with wild animals, captive animals are degraded in ability, but there is an important fact that the more skilled they are, the greater the loss.

If Xiong Ke, who is inclined to strength, and cats who are inclined to skill are kept in captivity since childhood, it is obvious that cats will lose more. The same is true of human beings. When a newborn child is locked up from an early age, his unique loss in dealing with others is the greatest. This kind of person can only be regarded as a human being in biology, but in fact it is no different from an idiot. The lion lies in strength, the tiger lies in technology, and its loss is undoubtedly greater than that of the Lions Club.

But even so, the winning rate of captive tigers is much higher than that of lions, not to mention wild liger.

(2) There is another fact, that is, in all the fighting records or videos in liger, it is not surprising that the little tiger defeated the big lion, but there is no case in which the little lion defeated the big tiger.

(3) In the case of a fight between a tiger and a lion, there are usually many male lions, but for a tiger, almost all female lions are chosen together regardless of the male lion. In fact, there is still a big gap between the female tiger and the male tiger, but there is not much difference. But if you really choose this way, you might as well take a lioness and a male leopard to fight.

But even so, the female tiger has a battle example of defeating the male lion. The male tiger is killing the female lion, and the female tiger can say that there is no chance of winning.

8. Evolution

Liger comes from the same ancestor. At present, it is impossible for wild liger to meet, but the territory of lions and tigers has overlapped in history, and finally they retreated to a corner in the northwest of India (called Asian lions). The final result is that Hu Meng is spread all over South Asia and Southeast Asia.

Before human interference, tigers once spread all over Eurasia, showing tenacious adaptability from extreme cold to extreme heat, while lions can only be confined to tropical and subtropical regions.

Biologically and geographically, the tropical rain forest is the richest land on earth, which is the living area of Hu Meng. In fact, it can also be compared by the competition between Jaguar and Puma. It is an indisputable fact that Jaguar is superior to Puma. Jaguar occupies the center of the tropical rain forest in South America, while puma can only be partial.

After listing all the data, it is found that the lion lags behind the tiger in almost all directions, and the wild lion without any physiological advantage can be said to have been completely defeated by the wild tiger!
