After punching in another legendary oasis, Bi Fang took Alpha and continued to move eastward along the canyon.

The full-fed West African crocodile lay quietly on the shore, opened his mouth lazily, and enjoyed the warm sunshine. There were several pigeons in the water behind him, and they were black, white, gray and light yellow. feather bird.

These birds are intricately coloured and stand out from a distance.

He stepped into the water, making tiny ripples, catching small fish in the river. Two of them seemed to be unsatisfied. After searching for a while, he set the target on the West African crocodile beside him, jumping on the shore, jumping quickly. Into his mouth, bowed his head and pecked.

【What kind of bird is this, it looks so beautiful】

[Hi, isn't it afraid that the crocodile will eat it? 】

[I've seen this, toothpick bird! 】

[I seem to have read that article, this is eating the meat residue in the mouth of the crocodile, it can also help to clean the mouth, the two are symbiotic relationship, so the crocodile will not eat birds]

"Uh" Bi Fang scratched his eyebrows, "This is probably fake."

【Ah this】

【Is it fake? 】

[It's over, I'm going to be slapped in the face by Fang Shen]

"The scientific name of the toothpick bird is the Egyptian plover, and the claim that it and the crocodile symbiotically coexist comes from the records of an ancient Greek writer named Herodotus, in a book called "History."

"This book records what Herodotus heard and saw during his travels, as well as the history of the Achaemenid Empire in Persia. It is the first prose work that has been completely handed down in the history of Western literature."

"There is a record of what you call a 'toothpick bird,' to the effect that, according to Herodotus, there was a Nile crocodile that would lie on the shore, open its mouth, and let a bird named 'trochilus' Fly into its mouth and help the crocodile remove the carrion and leeches from its mouth."

"But biologically speaking, crocodiles don't need teeth cleaning, they don't have teeth that can't be replaced like mammals."

"Each crocodile tooth is composed of three parts: functional tooth, replacement tooth and dental plate, and the stem cells in the dental plate bulge can develop into new replacement teeth. It is the special structure of the crocodile tooth that makes the new tooth replace the function The process of maturing teeth goes smoothly."

"Secondly, the crocodile's teeth are so widely spaced that they can't hold food scraps."

The teeth of crocodiles are cone-shaped, and the gap between the teeth is also cone-shaped. The main function of the teeth is to capture and kill animals, and then swallow them whole instead of chewing. Meat residue will not be stuffed with meat.

"Even though there will still be bacteria on the teeth, it is not something that a bird can solve. That is to say, the bird can hardly get any benefit in the mouth of the crocodile."

"The most important thing is that no other scientist has observed this phenomenon except Herodotus, who saw it more than 2,000 years ago."

"The pictures that are circulating on the Internet of Egyptian mylars flicking the teeth of crocodiles are actually digital reconstructions based on Herodotus' description."

For many years, people have believed in the toothpick bird and viewed the friendship between the toothpick bird and the crocodile as an example of mutualism between animals.

However, with the development of time, more and more people have raised questions. The biggest question is that more and more people are traveling to the African continent, and many of them are photographers or photography enthusiasts.

If they saw the funny scene of the bird getting into the mouth of the crocodile, they would have taken this precious shot anyway.

However, there is no such photo.

In addition, many scientists who have visited Africa have never seen this strange phenomenon.

"In the more than 2,400 years after Herodotus' death, only two zoologists claimed to have seen the scene of a toothpick bird flying into a crocodile's mouth to eat. , there is no real evidence, and it cannot be convincing.”

"Later, in order to unravel this ancient mystery, Mr. Howell, a bird expert from the University of California, Chou, made a special trip to the Gambella region of Ethiopia, Africa, for a two-and-a-half-month investigation."

"During the two-and-a-half-month expedition, Professor Howell worked tirelessly, leaving early and returning late, and discovered many interesting habits of the Egyptian plover, which were never known before. But he never looked at to the Egyptian plover catching the worm in the mouth of the crocodile."

"The last biologist, Thomas Howell, wrote a book in 1979 that roughly said that he had never seen this phenomenon himself, and that some authors in history claimed to have seen it, But these authors are not particularly reliable.”

"According to his research, even if Herodotus's story of the crocodile and the toothpick bird being good friends is well-founded, it is a very rare phenomenon, and this is definitely not the main food source of the bird, so the crocodile and the Egyptian mynah are not symbiotic. relation."

"That is, it shouldn't be seen as a paradigm of mutualism between animals."

"It's an individual behavior, and it doesn't become a commonality of a species."

"We were lucky to see the toothpick bird in the crocodile's mouth."

[It's hard to see someone I know, but it's really hard to be slapped by Fang Shen in the end]

[It's really hard to live in the wilderness, I really don't know one, I finally know one, but the result is still wrong]

Bi Fang laughed.

[Then why doesn't this crocodile eat toothpick birds]

[Yeah, what is this bird doing in the mouth of the crocodile? 】

"Probably eat some parasites or something."

Bi Fang stared at the crocodile a few times.

"All animals have a characteristic that they stop hunting when they are full."

"When crocodiles hunt, they will not lie down with their mouths open, but will float quietly in the water with only their eyes and nostrils exposed. When they lie down with their mouths open, it means they are full and will not hunt any more, even if the bird is full of food. Jumping around the mouth and not going to hunt."

"It's like those crocodile performances, often people get applause for such a thrilling scene by stuffing their hands or heads into the crocodile's grown mouth, and before starting such a performance, the crocodile has definitely been fed. full."

"Besides, crocodiles' reactions and movements are much slower than birds, and they can't really eat them, so they let it go, but it's not certain whether they will eat them or not."

As soon as the voice fell, everyone heard a loud clattering of teeth.

I saw the originally motionless West African crocodile suddenly closed its upper and lower jaws, only one of the two toothpick birds escaped, and the other was bitten without any suspense, and swallowed a few mouthfuls.

As soon as the blow was successful, the West African crocodile quickly turned its direction, swam toward the river, and disappeared.

It didn't take long for everything to return to calm again, and the crocodiles on the side did what they wanted, as if nothing had happened.

[Hey, Fang Shen actually said it right]

【It's true that people die for wealth and birds die for food】

【My God, it's amazing】

Several toothpick birds are pecking together on a small fish.

As it got deeper and deeper, the pollution level of the Heishui River began to decrease. It was no longer black, but light gray. Fewer and fewer wild camels were seen, and more West African crocodiles were replaced.

The crowds of crocodiles on the shore made the audience's scalp tingle, especially when Bi Fang was almost rubbing their edges, it reached its peak.

【Why do you feel that there are more and more crocodiles】

【This is almost gone】

【Scared, too scary】

[Fang Shen is too courageous]

"This is a normal phenomenon. Strictly speaking, the overlap between the lives of West African crocodiles and camels itself is not high. West African crocodiles do not rely on camels to survive, but basically rely on fish, so the fewer camels, the more crocodiles. Because where there are fewer camels, there are more fish.”

Bi Fang looked at the river and explained it briefly.

Excessive pollution will thin the fish in the river, reducing the rations of the crocodiles, and they will naturally stay away from the gathering places where the river is blackened by the pollution of camel feces.

This situation is not uncommon in Africa, such as the Mara River, which is one of the waters where hippos gather. In the dry season, there will be many hippos crowded in small lakes.

They excrete 8.5 tons of feces every day, and the accumulation of too much feces makes the environment of these small lakes very harsh.

The dry season is fine, because the area of ​​the water area is not large, and it only affects the surrounding area, but in the rainy season, the water area is connected into one piece and becomes a big river. Everywhere.

【I feel a little nauseous】

【Too heavy mouth belongs to yes】

【Want to visit】

【A little hanging】

【What kind of manure machine?】

The feces accumulated on the bottom of the water for a long time are fermented by microorganisms, which will produce gases such as methane, hydrogen sulfide, ammonia, etc., which will significantly reduce the oxygen content in the water, resulting in a large number of fish deaths in the river.

When the rainy season comes, the bodies of many dead fish will appear on the water surface of the Mara River, and these suffocated fish have also become a relatively special phenomenon.

And this phenomenon is still a vicious circle. The death of fish in the river will increase the accumulation of rotten matter, which will cause the river's purification ability to fail to keep up with the rate of pollutant production, and will be further polluted, making it less suitable for biological survival.

If it weren't for the Nile crocodile in it, unlike the West African crocodile, it basically survived by eating fish, and it would almost become extinct.

However, animal feces are not all bad. If the amount is appropriate, it will increase the number of organisms in the river and provide nutrition.

"We are at a suitable level here, and it is not polluted too much, so the number of fish schools is guaranteed, and there are naturally more crocodiles."

The tall camels disappeared, and even if there were crocodiles on the ground, it made the entire canyon look a lot more empty.

It is too empty, so that there is gradually an echo between the canyons.

When Bi Fang led the huge camel past, the West African crocodile didn't move, but a flock of birds was startled.

The bird hovered in the sky for a moment, waiting for Bi Fang to leave, and returned to the ground after a while, continuing to look for its own lunch in the river sand.

This canyon is not composed of many tall rocks, but a rift. The rock walls on both sides are as high as tens of meters, and a natural arched stone bridge can occasionally be seen overhead.

Looking at the magnificent spectacle like the gate of the gods, the audience at the screen is amazed, and even Bi Fang himself is relaxed and happy.

"Looking at the magnificence of nature can open your mind. If you feel that life is too tired, go to travel, go to the desert, Gobi, grassland, forest, starry sky, and giant trees."

Bi Fang breathed a sigh of relief, with a smile on his face, obviously in a good mood.

【No Money】

【Sponsored by Fangshen】

【Let's open a tourism foundation】

【I want you to be beautiful】

[I think Fangshen's next step should be the universe. I heard that rockets are not all commercialized? In other words, with Fangshen's current net worth, he should also be able to afford a ticket.]

[Sprinkling water, not enough for us to come together! 】

[Add one, collect money to send Fangshen to heaven! 】

【God! 】

Bi Fang made a few jokes with the audience, and was about to say something when a gunshot interrupted all the words that followed.

The sound of gunshots echoed endlessly over the canyon, and all the birds that had just stopped flew in shock, overlapping in the canyon.

what's the situation! ?

The crowd was startled.

Bi Fang's live broadcasts have been watched a lot, and the audience is all too familiar with this kind of voice.

Gunshots!

How could there be gunshots?

Bi Fang swallowed the rest of the words and pulled the frightened Alpha to be vigilant.

Animals are naturally wary of unfamiliar and loud sounds, especially herbivores, which are easily startled.

Alpha almost jumped up just now, but fortunately, Bi Fang pulled him down in time, and quickly pulled him under the rock wall, clinging to the stone wall, reducing the exposed surface as much as possible.

"Up there."

Bi Fang knew the source of the direction without identifying it. He was hidden under the shadow of the rock, and his face was not very good-looking.

To put it an exaggeration, with Bi Fang's current physical fitness and conditions, he would not frighten anyone in hand-to-hand combat, but he still had enough vigilance for such a big killer as a firearm.

But before Alpha could stand firm, the second gunshot sounded above the canyon. Judging from the sound, the distance did not get closer, and it should have fired two shots at the same position.

What are you hitting?

Bi Fang thought quickly in his mind, and tried to distinguish the type of firearm from the sound of gunfire.

The sound of different firearms is completely different, and many experienced hands can roughly identify the type of firearm from the sound of gunfire.

For example, the sound heard when a pistol is fired is similar to a firecracker.

That kind of "bang, bang, bang" burst sound, crisp and rhythmic, must be an automatic rifle.

The sound of the continuous "da da da" must be a submachine gun. UU reading www.uukanshu. com

To be more specific, for example, the M249saw is like a popping sound, and the mg42 is like cutting tarpaulin pants with scissors.

But the sound of the gunshots now sounded very dull, and for a while Bi Fang couldn't hear what it was.

But soon Bi Fang knew that he didn't have to think so much.

Not long after the second shot, Bi Fang raised his head and stared at the top of the canyon, and saw with his own eyes an animal with sharp horns that looked like a big deer falling from the edge of the cliff.

The powerful dynamic vision and neural reflexes also allowed Bi Fang to clearly see the red blood on the animal's abdomen.

It's just that no matter whether the wound is fatal or not, when Bi Fang saw it fall from a cliff tens of meters high, he knew that the gazelle was finished.
