Giant pandas sleep soundly.

Liu Wei could still hear the sound of its breathing.

He took the forepaw of the giant panda and said to the live broadcast room: "Brothers, there is a big difference between the forepaw of the giant panda and its bears, generally speaking, the forepaw of the bear is thick and blunt, but the giant panda is different, its forepaw is very soft. ”

Liu Wei pressed it with his fingers, and the flesh was very elastic.

"The giant panda's forepaw is flexible and easy for it to eat, and as you should have seen just now, it can hold food in its hand and eat it like a human.

When eating bamboo leaves, it likes to use its forefoot to knead the scattered bamboo leaves into a ball or a long strip and feed it to its mouth to chew, so that it is more satisfying to eat.

Just like when we sometimes eat bread, we will pinch the soft bread together to make it more chewy. ”

"I do that a lot!"

"You found out!hahaha!"

"I'm eating bread, fate! ”

"Don't expose me, I'm a quiet woman!"

Liu Wei looked at the barrage and smiled.

Then he said: "Let's take a look at its fur, the Qinling wild giant panda is slightly coarser than the Sichuan panda.

The color of the hair is roughly the same as what you see, mainly black and white, but the white is not really white, with a little taupe, and the black is not black, but there is a little dark brown in it.

The hair on the giant panda is also unevenly distributed, its back is thicker, up to 10 centimeters long, and the hair on its chest and belly is a little thinner, almost half the length of the back hair.

Generally speaking, the fur of the Qinling giant panda is still relatively rich, and even in winter, it can hang around in the wild in a sweater!"

"Ah Wei, don't giant pandas hibernate?"

"Giant pandas don't hibernate because there are still delicious and abundant bamboos that provide heat to their bodies in winter.

The main reason for the hibernation of bears is because of the lack of food, and the bear is large in size and has limited predatory ability, so vegetarianism is a large proportion of its diet.

Winter is the season when the plants are dying, and the food source of bears is in crisis, foraging in the cold will consume a lot of physical strength, and the food calories obtained are probably not enough to replace the lost calories, so they adopt the practice of conserving physical strength by sleeping, which is what we mentioned hibernation.

If other bears can find abundant food in the winter like giant pandas, they will not choose to hibernate.

Small mammals have a rapid drop in body temperature when they hibernat, but bears only have a body temperature drop of about 4 degrees, although their heart rate slows down by 75.

Once a bear begins to hibernate, its energy source shifts from diet to stored fat in the body.

Tom Evans, a field biologist in Alaska who works for the U.S. Fish and Wildlife Service's polar bear program, said the chemistry has changed dramatically.

When fat is burned, metabolism produces toxins, but when bears hibernate in hibernation, cells break down these toxins into harmless substances that can be recycled.

This biochemical action also allows bears to recycle water from their bodies and therefore do not urinate during hibernation.

Polar bears can use the fat-burning mechanism to maintain a waking hibernation, and they can stay active throughout the winter without hiding in their holes.

As we told you about the Tibetan brown bear when we were in science before, it can also concentrate when it is hibernating, relying on its sensitive sense of hearing and smell to determine the movement around the cave entrance, and if there is danger, it will wake up immediately.

In fact, many bears are able to stay conscious during hibernation.

Just now a viewer mentioned the problem of hibernation in bears, and I would like to add a little bit of knowledge about this to you!"

The audience in the live broadcast room did not understand everything, but they knew an important point - the reason why bears hibernate is because of the lack of food.

"Learned, learned!"

"Knowledge!"

"Write it down, go to school tomorrow and pretend to be a force!"

"Ah Wei, you just talked about polar bears, when will you take us to see polar bears?"

"And penguins!"

"Can you popularize sharks? I'll brush you with rockets!"

"Sweat! Ah Wei is so hard!"

Liu Wei explained with a smile: "Brothers, don't worry, as long as we live on the earth, we can meet the animals, I hope to be able to take the brothers in the live broadcast room to see together." However, at present, my plan is still in China, and I will finish the popular science of famous wild animals in China first, and then make the next step!"

"Yes, yes, yes!"

"Ah Wei, you can't paint cakes, do you?"

"Ah Wei does what he says!"

"Awesome, Ah Wei, it's over, I will always support you!"

Liu Wei: "Thanks to the support of our brothers, we are back to the giant pandas.

The appearance of the giant panda can be seen clearly through the lens, and then we will talk about its personality.

The giant panda has a very docile personality and does not attack people, on the contrary, it is easy to get close to humans, it should be the animal with the most contact with humans among the national first-class protected animals, and it is also the most famous in the world.

The title of national treasure is not something that ordinary animals can call, and it has an unshakable status and honor among the animals that operate in China.

Its natural cute image makes people look very comfortable, and its character also belongs to the master level of selling cuteness, when it first meets a stranger, it stretches out its forepaws to cover its eyes or bends over and lowers its head, looking like an autistic child, in fact, it wants to show a kind of shyness to attract human attention.

The giant pandas in the breeding base and zoo will play and play in various ways to attract people's attention.

In fact, for themselves, it is just a very ordinary way of life, but in the eyes of humans, their every action seems very comedy, which makes people feel dazzled to watch.

Just like the uncle in my arms just now, it didn't know that its movements could bring joy to the audience in the live broadcast room.

Maybe that's what makes it so attractive! Just like me, it's innate and likable!"

"What did you say?"

"Repeat you, please?"

"Ahem~tui~"

"Anything can be done to you, stinky and shameless!"

"Don't be like this, Ah Wei is very attractive, I like him anyway!"

"Huh~, it's just a lemon!"

"It's souring me!"

"Ah Wei, let's compare scissorhands, see if you are cute?"

The audience was all talking high, thinking that he didn't dare, but old fans all knew how cheap Ah Wei was after he let go.

“yai!” Liu Wei smiled and compared scissor hands in front of him.

“?????”

"Wow~, I threw up, what about you?"

"It's disgusting, it turns out that you are such Ah Wei!"

"Take the pass!"

"P, I can't stand it anymore!"

Liu Wei smiled: "Calm down, brothers, let's make a joke for everyone, adjust the atmosphere, I want you to know that I not only have the appearance of a handsome man, but also have an interesting soul!"

Today's live stream content has changed, and viewers are feeling the powerful shameless narcissistic impact from the streamer.

However, the barrage was very active at this time.

Sometimes, the audience likes to watch the anchor sell cuteness and cheapness, and the interaction between them will be more ordinary.
