After watching the river for a long time, the wildebeest leader finally decided to take the first step and give it a try.

The waves were calm, clearly reflecting the golden flowing hair of the wildebeest leader, and a round hoof hanging high slowly stepped in.

"Wow!"

The loud sound of the water startled away a circle of wildebeest on the shore, including the leader of the wildebeest, who had just wanted to give it a try, and the wet hooves left one round mark after another on the mud.

The river, which was originally crowded with wildebeests, instantly freed up a semicircular clearing with a diameter of more than 10 meters, which also allowed Bi Fang and the audience to better observe what was happening.

In a clearing surrounded by wildebeests, a Nile crocodile with a visual body length of more than four meters bites a small wildebeest.

A successful hunt!

From the waist and abdomen to the hips, the whole lower body of the little wildebeest was firmly torn by sharp teeth, and he could not move, leaving only the two hooves of the upper body to keep kicking, and even then gradually began to weaken.

Many wildebeest had parched mouths as they made the long journey, munching on yellowed, waterless hay along the way, and their thick tongues licked their lips and noses at high frequencies, giving out low gasps.

In the face of the calm river, many wildebeest choose to risk their lives to drink two sips of water before crossing the river.

The crocodile did not hesitate to strike at this time.

The one-metre-long wildebeest was too small for an adult Nile crocodile to hunt effortlessly, and without even using the crocodile's signature death roll, it raised its head high and threw it to the side.

With great force, the sound of fractures sounded, and the bend of the little wildebeest's body was exaggerated, and the vertebrae were obviously broken on the spot.

None of the wildebeest attempted to snatch their companions back, and they watched as the hunted Nile crocodile returned to the river with its booty, seemingly indifferent to their death.

Only a few equally strong Nile crocodiles on the side stepped forward to grab food with their companions, adding to the eerie silence.

[This tail flick is handsome]

[This picture is too clear, it shocked me, when do I want to make a whole old party with the same drone]

【You will find that you can't afford it】

[Millions of drones to learn about]

Many viewers admired the crocodile's strength, while others focused their perspective on the wildebeest.

[This wildebeest is so cold-blooded, there is no reaction at all]

[Cold-blooded? This is nature, nature is like this, there is no vitality, everything is the subjective feeling of human beings themselves]

"It's normal to be indifferent." Bi Fang replied after seeing the barrage, "Or rather, this is their survival strategy, just like we people will actively avoid a big hole on the road when they see it, instead of stepping into it." ”

The wildebeest can become the largest group of large and medium-sized wild animals in the entire African savannah, and even in the world, so it naturally has a unique survival strategy.

Bi Fang, who was sitting on the branch, adjusted his sitting posture and raised two fingers in front of the camera: "The actions of the wildebeest herd follow two rules. ”

"The first is to follow the leader or companion, and almost blindly follow."

"When wildebeest passes through a new area, they tend to line up one by one, and if we follow a herd of wildebeests, we often see a scene where the wildebeest herd is halfway through and suddenly an individual ducks dodges to the right."

As if to confirm Bi Fang's words, the semicircle that had been vacated by the hunting of the little wildebeest had not been filled even if the crocodile left.

The leader of the wildebeest, who was supposed to cross the river, was again in a choice, and many of them went to the river to drink, but no wildebeest went to the semicircle that had just been vacated.

】

Obviously other places are also unsafe, crocodile swarms.

Such a scene undoubtedly surprised many viewers.

[It seems to be true]

[What is it converted to?] Once bitten by a snake for ten years afraid of the well rope? 】

Bi Fang continued: "The reason for this may be that the first wildebeest to do this touched a snake or smelled a predator, and then for the next half hour, everyone behind repeated the path, and the whole team bent with it, even if the danger was gone. ”

"It seems stupid to us that rule, but it keeps animals with low intelligence safe."

"The same thing happens when crossing a river. It looks stupid, but it allows them to cross the river smoothly in the most difficult places. ”

After a pause, Bi Fang began to make the second point.

"The second point of the rule is that the movement of the group is more important than anything else."

"Zoologists once saw a scene near the Mara: a female wildebeest crossed the river and found that the baby wildebeest was missing, while the other individuals were moving forward, and she wanted to return to the river to find her young."

"When the little wildebeest heard its mother's call, it also responded and swam to her mother, but it could not climb ashore, because the place where her mother was staying was four meters high, and it was a broken slope, but fifteen meters next to it, there was a relatively gentle place."

After a pause, Bi Fang added: "I don't know if you have ever encountered danger, if you think about it carefully, you will find that in danger, it is difficult for our brains to notice changes in the external environment, maybe next to the safety zone, but you can't notice it when you are in fear and panic." ”

[I haven't encountered any danger, but I feel that what Lao Fang said is similar to what I felt when I gave my first speech, my attention was all on the draft, and then I hurried down, and in the end, I didn't know what the reaction of the people below was]

[Good guy, you can feel it when you compare it like this]

"This is true of all humans, and even more so of animals with more instincts, and the little wildebeest instinctively chased in the direction of its mother, struggling on that broken slope all the time."

"If the mother wildebeest can move to a gentler 15 metres away from the shore and guide her helpless child, then the baby wildebeest may be able to come ashore."

"However, the momentum of the group march was too great, and the female wildebeest did not hesitate for too long before turning around and running towards the large group, choosing to give up."

"The little wildebeest, which was finally abandoned, struggled to exhaustion in the same place and fell back into the water, where it became a crocodile ration."

Most of the audience who heard this were speechless, and they had a feeling that they couldn't speak.

Sad?

Or irritated?

Nothing.

Faced with her own children, the female wildebeest finally chose to follow the large group.

These are their two major strategies, blind follow and follow.

Faced with the silence in the live broadcast room, Bi Fang smiled: "This survival strategy of wildebeest is actually in stark contrast to the survival rule of zebras. ”

"Zebras generally have a breeding herd as a family unit, i.e. consisting of a head horse and several females and their cubs."

"The relationship between family members is very close, especially the males, who follow their offspring closely."

"Once, in the Ngorongoro volcano area, a zoologist accidentally killed a young male zebra while wearing a radio collar on a young male zebra who accidentally left the herd, so the father of the baby zebra began a frenzied search, and he searched all the family groups in the area for 10 months."

[Grass, the knife I am]

[This comparison ......]

[Although I wasn't so moved, I still had a little poke]

[Wait, did the old man say Ngoro twice? ] 】

Bi Fang shrugged: "That place is called Ngorongoro Crater, I am not wrong, it is the extinct volcanic crater of the Great Rift Valley in northern Tanzania, known as the 'Garden of Yindian in Africa', which is a very complete and beautiful volcanic crater in the world." ”

"Zebras are so persistent, families are so close, but here their population is only one-fifth that of wildebeests."

"Despite the fact that wildebeest is born in danger and surrounded by predators who have been waiting for a long time, the foolish-looking wildebeest has built the perfect strategy to adapt to the entire ecosystem, with the largest amount of feed and the smallest amount of prey, making itself the largest kingdom in the Serengeti."

The beauty of the grasslands and the predators coexist, yet the millions of wildebeest survive, making it a miracle in the mammalian world.

"Many of the actions that seem ruthless and indifferent to us are one of the keys to the continuous reproduction of the collective."

"That's why I rarely and don't like to anthropomorphize animals, it's hard to understand the perspectives of different species, and we don't need to understand, we just need to record, as a spectator."

Bi Fang's voice landed, and the noisy sound of raising water rose again.

This time it was no longer a hunt, but finally the wildebeest stepped out and led the army across the river.
