Liu Wei: "Brothers, Jiang Xiaobai is still a little uncomfortable with the new environment, so I won't bother it too much."

Let's give you a brief introduction to polar bears, and then compare the combat effectiveness of bears. ”

"The polar bear is the largest and most carnivorous of the bears, and more than 90 percent of its diet is meat, such as seals, fish, and sometimes a little bit of herbs such as berries.

Polar bears are the pickiest eaters of all bears, and the brown bears and black bears we've seen before have a habit of scavenging, but polar bears only like to eat fresh meat and have no habit of storing food.

Recently, however, scientists studying polar bears have discovered that polar bears are also devouring stranded dead cetaceans, proving that they are changing their habits.

An important reason for the change of polar bears' living habits is that global warming leads to the melting of ice, which leads to the loss of habitat of seals, which directly leads to the reduction of food for polar bears.

In some areas where food is extremely scarce, polar bears can even kill their own children to feed their hunger.

Scientists predict that polar bears will become extinct around 2100!"

"Time is running out for polar bears!"

"There isn't much time left for humanity!"

"Time is running out for all creatures!"

The barrage on the screen of the live broadcast room is the same.

It looks like a joke, but the meaning is deep.

Liu Wei continued: "The polar bear is also called the white bear, the name comes from its transparent hair color, in fact, the polar bear's body skin is black, its hair is different from the hair of other creatures, it is a colorless hollow tube, under the refraction of sunlight, the color we see is white."

This hollow fur has a good water release and heat insulation effect, which is conducive to the survival of polar bears in the low temperatures of the polar regions. ”

"Then let's talk about the hunting methods of polar bears, and there are two common hunting methods.

The first is to wait for the rabbit, for example, when preying on the seal, it will find the seal's breathing space on the ice in advance, and then wait for the seal to emerge, and launch a surprise attack at the moment when the seal emerges, piercing the seal's skin with its sharp claws, and dragging the seal out of the water with the strong force of its limbs.

Another option is to dive directly into the water to cut off the seals' retreat and launch a surprise attack on the seals closer to the shore.

Polar bears are very good swimmers, and humans living in polar regions once regarded them as sea beasts, as long as they avoid going head-to-head with seals in the sea, the chances of successful predation are high.

After eating, it will also clean its own hair and add blood to the same as a feline!"

The brick mover sent out the ice wide fall × 999

Aquaman sends a support meow ×166

A fish sends out Rhythm Storm × 20

……

"Thank you brothers for the gift!", Liu Wei glanced back at the polar bear, which had quieted down and was lying on the rock, but did not let down its guard, and consciously observed Liu Wei.

Liu Wei smiled and waved his hand, turned back to face the camera, and continued: "Next, let's compare the combat effectiveness of bears to see who is the real bears?"

We compare the Kodiak brown bear, the largest of the polar bear and brown bear subspecies, and the Asiatic black bear and the American black bear among the black bears.

First, let's take a look at their weight, which affects the size of the strength.

The average weight of an adult male polar bear is around 500kg, and the largest individual can weigh up to a ton.

The Kodiak brown bear and the Peninsula brown bear are the two largest subspecies of brown bears, with the average weight of an adult male Kodiak brown bear being around 400kg, and the largest individual can reach 750kg.

The two subspecies of black bears, the American black bear and the Asiatic black bear, are only 400 kg.

Polar bears can be said to crush the latter two!"

"Jiang Xiaobai is just an adult, and he is the size of a brown bear!"

"Polar bears are indeed the largest bears!"

Liu Wei: "Let's take a look at the hardware equipment, first of all, the length of the teeth, the canines and cracked teeth of the polar bear are the most developed of the bear family, and the average length of the canine teeth reaches five centimeters.

The average length of the canines of the Kodiak brown bear is 4 cm, the Asiatic black bear is 3.5 cm, and the American black bear is 2.9 cm.

In terms of bite force, polar bears are also the strongest, reaching 960 Newtons, Kodiak brown bears 749 Newtons, Asiatic black bears 722 Newtons, and American black bears 598 Newtons.

As I mentioned earlier, the bite force of a beast is affected by many factors, and its performance is not stable, so scientists have introduced the concept of bite quotient to compare.

The bite quotient refers to the unit bite force, so that we can ignore the weight factor and simply compare the bite force.

Polar bears still have the highest bite quotient at 107, Kodiak brown bears 89, Asiatic black bears 78, and American black bears 74. ”

"Very objective!"

"Data comparison, at a glance!"

"It doesn't feel like there's anything to compare, I declare that the polar bear is the bear boss!"

"Listen to Ah Wei again!"

Liu Wei continued: "Another piece of hardware, an important weapon of the bears, the claws.

Let's take a look at the length of their claws, the average length of the claws of adult male polar bears is more than 5 cm, which can reach 10 cm, and the average length of the claws of adult male Kodiak brown bears is about 8 cm.

Just looking at the length of the claws, the Kodiak brown bear has the upper hand.

However, the claws of the polar bear are the sharpest of the bears, which is related to the fact that it often preys on other animals, and the claws of brown bears and black bears are somewhat rough and blunt, and they are not as lethal as polar bears.

Polar bears also have the largest palms of the bear family, with a palm force of more than a ton, and when they hunt seals on the ice, they often launch a surprise attack and slap the seal directly on the head with one palm, slapping the seal to death on the shore.

The Kodiak brown bear is not as large as a polar bear in weight and palms, but it has very well-developed shoulder muscles, and its towering shoulders can provide strong strength to the palms, and the palm strength is not inferior to that of polar bears. ”

"Between the two of them!"

"The lethality is still stronger than that of polar bears!"

"Black bears don't exist anymore!"

"The real hammer black bear is the third in ten thousand years!"

Liu Wei: "Finally, let's take a look at the competition between the three bears, the overlap between the living space of polar bears and black bears is very small, only a few bays in North America and Canada will meet, when black bears meet polar bears, they will choose to escape, polar bears give black bears a strong deterrent."

Polar bears and brown bears have more opportunities to meet, and generally speaking, if there is no huge weight difference between the two, polar bears will keep their distance from brown bears when facing brown bears, and will not easily disturb brown bears.

It may be caused by the difference in the lifestyle of the two animals, polar bears live on the ice all year round, good at dealing with sea beasts, in the face of brown bears, pure land beasts, in the choice of combat methods, a little overwhelmed, and brown bears are also extremely territorial animals, full of aggression, polar bears will be afraid.

But if the two are to do it, I believe that the polar bear's weight advantage and killing experience will give it a higher chance of winning.

There is also a high chance that a brown bear will meet a black bear, but the black bear is too weak in front of the brown bear, and there are often cases of brown bears preying on black bears. ”

"The black bear is a scum!"

"Black Bear: Brothers, can you give some face?"

"Ah Wei, when will you take us to see the Kodiak brown bears!"

"There is a chance to take you there!", Liu Wei replied, "To sum up, coupled with the temper and aggression of wild beasts, I personally feel that the polar bear, which is mainly carnivorous, is stronger than other bears that are mainly vegetarians!"

"Finally, let me give you a brief overview of the competition between bears and felines.

Of course, we are talking about the tiger and lion are the two big names of the cats, the lion has little intersection with the bears, and there is no case study of lions and bears in the wild.

We mainly mention tigers.

In the Russian Far East, the northeast of China, and Southeast Asia, there is a high overlap in the living space of tigers and bears.

In the tiger's diet, there are brown bears and black bears, but only about 1%.

There is no doubt that the natural predator of the black bear is the tiger, and the odds of defeating the tiger are slim to none.

Yes, the relationship between brown bears and tigers can be said to be natural enemies of each other, and there are real cases of Siberian tigers preying on brown bears, most of which are female brown bears.

In turn, there are real-life cases of brown bears killing Siberian tigers.

There is not much difference in strength between the two, just from the weight comparison, the brown bear Xiaoyou!"

The audience very much agreed with Liu Wei's analysis, and on the live broadcast screen, the gifts began to scroll rapidly again.

Liu Wei got up and patted the dust on his buttocks, and looked back at the polar bear again, "Hey, Jiang Xiaobai, do you want to come and play with me for a while?"

Try to take two steps forward.

The polar bear immediately moved and stood up.

Very cautious.

"When the keeper feeds it, let's come and see it again!", Liu Wei remembered what happened to Director Zhou, and smiled at the camera, "Brothers, insert a hard advertisement, this polar bear is a new member just introduced by Jiangcheng Zoo, and viewers who like polar bears can come to Jiangcheng Zoo to watch!"

After speaking, Liu Wei opened the door and walked out.

Director Zhou greeted him, stretched out his hand and said, "Mr. Liu, thank you for helping to publicize!"

Liu Wei said: "With a lot of effort, there is a star in Jiangcheng, and I am also very happy, by the way, I named it Jiang Xiaobai!"

"Jiang Xiaobai!", Zhou Yuanchang read it twice, it was very familiar, and then smiled, "Jiang Xiaobai's name is very cute!"

In his opinion, it doesn't matter what the polar bear is called, what matters is the person who named it.

can also use Liu Wei's fame to promote a wave.

"Old Zhou, Jiang Xiaobai may have to adapt for a while, let the breeders and experts pay more attention, if you find that the polar bear has abnormal behavior, you can contact me at any time!"

"Okay! Mr. Liu, I'll send you!"

Director Zhou sent Liu Wei out of the zoo and waved his hand, "Mr. Liu, you go slowly!"

Liu Wei got into the car.

A picture of the system came to mind.
