"You obviously have some prejudice against dingoes. The dingoes are different from domestic dogs, and although they belong to the same family of canines, they are a subspecies of gray wolves. It is called a wild dog only because it looks like a domestic dog. You know, they have another name, it's called the Australian Red Wolf!"

After pouring another sip of water, Ye Xuan explained: "Many people may not know that there were no wild dogs in Australia before, and when Southeast Asians immigrated to Australia, they brought a few wild dogs on the boat, so they bred here. Once the top carnivore in this land, the ferocious thylacine, was eventually extinct. And the main reason for the extinction is the complete defeat in the fight against the dingo. Do you think the main killer who can wipe out the murderous thylacine will be weak?"

"Some viewers are right, the dingo is really small, the largest is only 30 kilograms. But they retain the genes of gray wolves, have a strict hierarchy, and know how to use tactics. Generally, there are 5-12 wild dogs, forming a small group, and when it is necessary to catch large animals, they will call friends and gather several small groups to hunt. In Australia, they eat everything from insects and bird eggs to cows, sheep, kangaroos and even freshwater crocodiles. If I encounter one alone, I can easily kill it, but if I meet a group, even if I win, it will definitely be a miserable victory. ”

"In the Northern Territory, there are frequent clashes between dingo packs and local village dwellers. Because they have no natural predators and have abundant food, their populations are growing rapidly, so they often threaten farms. Just a few years ago, two dingos stormed a house in the countryside, attacked a 10-year-old boy, and ate him alive. In fact, there have been hundreds of dingoes attacking humans. This tragedy made the local government determined to start a batch hunt of wild dogs every year. ”

Ye Xuan said this, paused, and continued with a strange expression: "Australian dingos and African hyenas have one thing in common, that is, they eat their prey while they are still alive. However, the body of large animals is generally protected by thick fur and fat, and it is not easy to bite open. Therefore, they will attack the most vulnerable parts of their prey, such as chrysanthemums..."

After listening to his words, all the viewers in the live broadcast room subconsciously covered their chrysanthemums.

"Hold the grass, this special dingo is too evil. ”

"666, isn't this TM a ** hero!"

"God TM ** Hero, I'll obey you!"

"Mr. Chen Duxiu, can I touch your trophy?"

"Australian dingo: eat my weak spot with a blow, chrysanthemum burst bite!"

"Nima, I'm scared of Lao Tzu Chrysanthemum!"

"Haha, no wonder the patriarch doesn't want to have a hard anal with them. ”

"The wilderness is so scary, I want to go back home. ”

"It's an evil creature that breaks down doors, I like it. ”

After resting, Ye Xuan stood up and began to prepare to start building the shelter.

There are not many trees on the edge of the pond, only five or six, and most of them are so sparse that they cannot be used to build hammocks.

Only the last branch is luxuriant, still growing on the opposite bank.

"Ladies and gentlemen, let's go to the other side, but be careful, there are probably freshwater crocodiles on the shore nearby. ”

With that, Ye Xuan held the wooden stick and walked cautiously along the pond towards the opposite bank.

Crocodiles are ectotherms, and their bodies are like a giant battery, relying on absorbing outside temperature to keep themselves alive. And like snakes, they often don't need to eat for a week or two or even a month after they are full. So most of the time, crocodiles like to lie on the shore in sunny weather and bask in the sun.

At this time, the danger of crocodiles is much less than when they are hungry. As long as they don't actively provoke them, they won't actively attack people.

Sure enough, halfway through, a freshwater crocodile appeared in the clearing in front of me. The freshwater crocodile was about two meters long, lying quietly on the ground, with its eyes closed, its bloody mouth fully open.

Although motionless, the momentum is still terrifying.

Seeing this scene, Ye Xuan slowed down his movements, bypassed this freshwater crocodile, and continued to move forward. At the same time, he lowered his voice and said softly: "It is basking in the sun now, as long as it does not take the initiative to provoke, it will not pose a threat to me." There must be freshwater crocodiles basking in the sun around here, so I have to be careful. ”

As he expected, he didn't take a few steps when he encountered a freshwater crocodile again, in exactly the same posture as the previous one.

Honestly, it's so exciting to walk around a few freshwater crocodiles. Don't look at Ye Xuan's expression that looks very relaxed, in fact, the muscles up and down his body have been in a tense state, ready to run away at any time.

At this moment, the audience in the live broadcast room also sweated for him, and at the same time felt very enjoyable.

"Awesome, it's exciting!"

"Grass, look at Lao Tzu's sweat with one hand. ”

"Crocodile:, it's the patriarch, hurry up and play dead!"

"Freshwater crocodile: you can't see me, you can't see me..."

"Can anyone tell me why many crocodiles open their mouths when they're basking in the sun?"

"It's a deterrent to other beasts from sneaking up. ”

"Pulling a few handfuls of eggs, the crocodile opened its mouth to allow the toothpick bird to clean its mouth. ”

"Obediently, you started?

At this time, Ye Xuan had already come to the acacia tree on the other bank. After making sure that there were no freshwater crocodiles around, he put down his backpack and was about to start building a shelter when he suddenly found a quarrel in the live broadcast room. More and more viewers joined the debate, and countless barrages became black clouds, completely covering up the live broadcast picture.

For the anchor, this is a good opportunity to interact, and now Ye Xuan is no longer the rookie he once was, so he naturally will not miss such a good opportunity.

Seeing this, he coughed twice and hurriedly said: "Ladies and gentlemen, why don't you start a poll like this, see what is the option with the most votes, and finally I will announce the correct answer, how about it?"

Hearing him say this, the audience immediately agreed.

Soon, he used his mobile phone to initiate a poll in the background, and the options were naturally the most popular on the barrage.

At this moment, the enthusiasm of the audience has been fully mobilized, and they have clicked the mouse to vote. In less than a minute, 110,000 viewers had already cast their votes.

Looking at the votes, the ending was not unexpected, and the number of votes for [Toothpick Bird Cleaning Mouth] was the highest, far exceeding the second place [Deterring Other Beasts] several times. As for the number of votes for [Heat Dissipation], there were only a pitiful 87 people, and even the number of votes for the nonsense reason of [Courtship] reached more than 6,000.

Facing the urging of the audience, Ye Xuan first took a sip of water unhurriedly, and then slowly spoke: "First of all, I'm sorry to tell you that the story of the toothpick bird and the crocodile is pure fiction. In this world, there is no such bird as a toothpick bird. Believe it or not, but it's true that it only exists in stories, not in reality. ”

Suddenly, the barrage exploded again.

Ye Xuan smiled and announced the final answer, "This time, the truth is in the hands of a few, and the reason why crocodiles open their mouths in the sun is to dissipate heat. As we all know, crocodiles are ectotherms, they cannot control their body temperature, and can only rely on absorbing external temperature to restore body temperature. However, when the outside temperature is too high, the core temperature in their body will gradually increase, which will cause damage to their bodies. ”

"Humans can lower their core body temperature through sweat and urine, and dogs can use their tongues. However, crocodiles are not able to sweat and have a very short tongue, so they can only dissipate heat by opening their mouths wide to reduce the core temperature of their bodies. If you're careful enough, you'll notice that crocodiles only open their mouths during the hottest hours of the day. ”
