These big guys all have horns and there are many of them. They are all gathered together at this moment, which looks quite spectacular.
On the snow, Bifang and six dogs were buried in the snow, with seven pairs of big eyes rolling around, as if they saw hundreds of huge barbecued heads with bones stuck in them running across the endless snowfield.
Goudan barked softly and tugged at the corner of Bifang's clothes with his paws, as if wanting him to come on quickly.
Bi Fang didn't show too much excitement. He knocked Goudan's head, rubbed his chin and thought: "There is no cover, it's a bit troublesome."
As soon as he finished speaking, the drone took off high into the sky, clearly showing the landscape of hundreds of meters in radius. They were all snowfields, unusually flat, and there was no suitable cover to cover his body.
Such a landform would be easily discovered even if it was 50 meters away, let alone 20 meters away.
It's just that people came up with the method after all. Bi Fang quietly unfolded the musk ox hide and poured dry snow on it. Although a little black hair could still be exposed occasionally, on the surface, it seemed to be integrated with the environment.
, not so eye-catching.
Bifang lifted a corner of the musk ox hide, dug inside, and slowly approached the reindeer herd with the musk ox hide on his head.
Musk ox skin is really useful. You can sleep at night and use it as a shelter during the day.
"Although this is not the first time we have encountered reindeer, I still have to say that what we encounter this time may be different from the previous two."
Climbing forward on his stomach consumes a lot of energy, and the close contact with the snow is also very cold. After crawling for a while, Bifang stopped to take a breath and temporarily regain his strength.
It can be said that herbivores are preyed on by carnivores at any time. Usually, when herbivores encounter predators, they will just choose to escape quickly.
But for some herbivores, escape is not the only option, like the musk ox Bifang encountered in the Arctic.
"Reindeer are social animals. They usually live in a 'family group' of 6 to 13, and several 'family groups' form a huge group, usually in the hundreds. Such a number allows them to
Under the right conditions, a unique formation can be formed to defend against the enemy."
Formation?
This word with a strong flavor of ancient military art made water friends look at each other.
Do deers also do this?
Bi Fang nodded, confirming the audience's guess.
"The formation of the reindeer is called the whirlwind formation. It is named because it is similar to a whirlwind. However, this formation is not complicated. It means that the entire reindeer herd rotates around a common center. After all, they are just animals in the end.
It succumbs to instinct, but it is quite powerful against predators in nature. Once the formation is activated, not to mention wolves, even tigers are powerless."
"When predators hunt prey that live in groups, they usually only attack some of the weaker individuals. However, in the reindeer whirlwind, the weaker individuals in the group are located in the center of the formation, which prevents the predators from locking in on their ideal targets.
prey.”
"In order from the inside to the outside, the speed of the reindeer whirlwind gradually increases. The farther out the reindeer are, the faster they are. And those in the outer area of the reindeer whirlwind are almost all the strong ones in the group!"
Reindeer is a large hoofed animal. A strong reindeer can weigh more than 200 kilograms, and some particularly strong individuals can even weigh more than 300 kilograms.
In addition, adult reindeer have long, complexly branched antlers, which constitute the reindeer's powerful attack power.
"After the reindeer formation is activated, the reindeer on the periphery will start running at high speed. If predators rush into the formation at this time, what awaits them will be being continuously hit and trampled by the strong reindeer that come one after another.
You are also likely to be punctured by antlers during this period, so many predators are powerless to do anything about it."
After resting, Bi Fang put the musk ox skin on his head and continued to crawl forward.
However, the fundamental reason why humans show completely different behaviors from other creatures is that they are good at thinking. Someone soon pointed out the bug in this formation.
[If it is a whirlwind, it should not be easy to move. Then when it is tired and has no strength, wouldn’t it be waiting to be killed? 】
[Yeah, when you’re tired from running, why don’t you take a rest]
Bi Fang stopped again when he saw the barrage, blinked and said with a smile: "You are absolutely right, so when humans came, the reindeer became extinct."
The audience was dumbfounded.
【Is this thing useless to humans?】
【As expected of me】
"Humans are actually an animal that is quite isolated from nature. Well, this is not easy to explain. Simply put, in the process of evolution, we humans have not actually co-evolved with many creatures. Therefore, most of them
The resistance methods evolved by animals do not work for us."
"Reindeer themselves are animals that are good at running, and the temperature in their living environment is very low, which is beneficial to the body's heat dissipation. Therefore, reindeer whirlwinds can be maintained for a long time, and carnivores in nature do not have the ability to do so like humans.
With the same logical thinking ability, they will only make judgments based on the situation at hand and will not wait too long."
"On the other hand, when a large number of reindeer run together, it will cause a lot of splashes on the ground and produce a lot of vibration and noise. Obviously, this is also a big deterrent to predators.
So they usually leave when faced with reindeer cyclones."
Unfortunately, these two tricks are useless to humans.
The Guizhou donkey has no skills. As long as he sees through the nature of the reindeer whirlwind, humans will not be scared at all.
For humans, powerful formations in nature such as reindeer whirlwind are ineffective, especially in ancient times, humans who learned how to use tools for long-range attacks were invincible.
"The reindeer formation is powerful, but in fact it is very rigid. It just rushes in one direction. It is not as threatening as the musk oxen's group counterattack. That is the real danger."
The formation of musk oxen is to surround the weak ones, and then the strong musk oxen will confront the predators and carry out counterattacks and fierce attacks, which is flexible and tricky.
Reindeer that can only circle in circles are dangerous, but as long as you take precautions in advance, it's nothing.
"In the past, reindeer were captured either on frozen rivers or in hills. The terrain was not convenient for them to deploy their formations. They had to flee in all directions when encountering danger. It is different now. We are on an open ice field, so we need to pay attention.
.”
Having said this, Bifang was quite close to the reindeer. He held his spear and waited for the opportunity to move.
At a suitable moment, Bifang, whose energy and spirit had been raised to the limit, suddenly jumped out.
The reindeer suddenly woke up.
As Bi Fang said, all the reindeer formed a circle on their own, one layer after another. The strongest deer on the outside ran quickly around the circle. They rotated closely along the "eye" in the center of the spiral shape. Under the trampling of the deer's hooves, the earth
shock.
Just like the galaxies rotating around the center of the Milky Way, it is also a tropical cyclone rotating on the ocean.
