The Saharan wolves, who had wandered for a day and a night, were so hungry that they could see that the sub-zero bushes and weeds were the boundless loess, and the only thing they could do was dig through the soil for beetles to eat, except to gnaw on the grass like fat lambs.

During the day, the Sahara was as hot as a teppanyaki, and even the beetles were buried deep underneath and disappeared, and only choking smoke and dust were found in the soil.

Several secondary wolves stopped to lift their hind legs and itched, they gnawed at their fur with their fangs in an attempt to keep the damned fleas away, and from time to time their slanted gaze drifted to the leader of the big wolf, as if they were implicitly dissatisfied, but they were hidden by authority.

The head wolf is the strongest and most intimidating of the wolves, and he is larger than the wolves in his physique alone, and enjoys the service of the she-wolf.

The deflated hair fluttered in the air, and they wanted to shed their fur and settle down at ease, but when they thought of the bitter cold of the night, the slightly loosened hair follicles took root solidly.

It is hot during the day and freezing at night.

This is the Sahara.

Just as several second-level wolves landed at the end of the group and secretly poked and poked to express their dissatisfaction, a low wolf howl woke up the entire wolf pack.

The wolves immediately cheered up, walked quickly to the head wolf, and looked into the distance.

It was three camels, two large and one small.

There was not a single tree for miles, and the huge camels that stood on the ground hung their shadows, which stood out in the eye.

Come to life.

Smoke billowed and wolves charged at the little family of camels, their green eyes glinting with hunger.

[This wolf is a little small]

[Indeed, it seems to be much smaller than what God encountered before]

[What kind of wolf is this, a desert wolf?] 】

The drone can automatically zoom in on the scene, and the two sides of the confrontation seem to be close at hand, and the audience can see more realistically.

There are a large number of wolves surrounding the three camels, but the quality is a little worse, and the physique feels more than a circle smaller than the Arctic wolf.

Bi Fang himself was too far away, and there were not enough references nearby, and the only thing the audience could compare was the besieged camel, so they were not sure whether the wolf was too small or the camel was too big.

However, although the wolves were a little smaller, Bi Fang counted them carefully under the scorching sun, and found that there were actually seventeen wolves!

Once there are more than five animals in the same space, a certain level of visual effect can be formed.

Think about the five dogs you encounter at home, although the number is very small, but when you really pounce, you will have the inner feeling of "what a lot".

The rise in the number of animals is by no means just an increase in numbers, which is why Bi Xiang has never liked social carnivores, and it is always a tricky thing to encounter.

The sheer number of wolves made the charge seem immense, and let people know that this small pack of wolves should not be underestimated.

For this reason, Bi Fang did not take the liberty of approaching, and after getting closer, he hid two hundred meters away, lying on the ground and watching the development of the situation.

"That's a desert wolf, also called an African wolf, you are right, they are indeed small, and they are much smaller."

"I said before that there is a Bergman's rule, which means that for homeotherms, between individuals of the same species or close relatives, those who live in cold environments have a relatively larger body size."

Bergman believes that this is due to the fact that as the animal increases in size, the relative body surface area decreases, resulting in a smaller body surface divergence ratio, which is therefore better able to conserve heat to adapt to the cold environment at high latitudes.

"This law is not a theorem and is deeply flawed, but in the case of mammals, more than 90 percent of species agree. So we can easily extrapolate that the closer to the equator, the smaller they tend to be, as typical of desert wolves, which weigh less than half the weight of Arctic wolves. ”

"Although the desert wolf is called a wolf, it is not a wolf in the strict sense, but an independent species of canine dogs."

Bi Fang lay on the yellow earth and explained the origin of the gray wolf a little, which also gave the audience a better understanding.

The gray wolf, as a group predator, has spread almost all over the world, but it has disappeared only on the roads of Africa, and the reasons for this are complex.

"In general, the wolf is the name of the gray wolf of the canine genus, and the ancestors of the gray wolf, including the gray wolf, have always been between Eurasia and North America, and have not entered Africa, the reason may be related to the migration memory and environmental differences, which leads to the absence of gray wolves in Africa."

"That said, some of the early canine migrations came to Africa, because there were still canines in Africa, and the African wolf was one of them."

[Then why is it called a wolf]

[Maybe it's a language habit]

"It is indeed a linguistic habit, for example, the African hyena, although they are called hyenas, but in fact they are not canines, and the hyena family under the cat suborder is neither a cat nor a canine, it is an independent species."

"It's all a matter of translation and naming, in the past, the translation and naming were not rigorous enough, and the hyena looked like a dog at first glance, so people gave it a name with 'dog'.

There are many similar historical problems, such as the cheetah is not a leopard, and the cougar is not a lion. But these names are already widely used as official names, so they will be wrong and will not be changed. ”

It is also because it is not a wolf that the habits of African wolves have some subtle differences from wolves, such as flexible organizational forms.

The social organization of the African wolf is very flexible, the size of the group varies according to the available food, enough food to eat, can form a large group, no food, the number scatters, and becomes a small group again.

On the coarse sand, African wolves charged the camels, over and over again, bringing up billowing smoke and dust.

Strangely, they were not in a hurry to attack, but with the dexterity brought by their smaller bodies, they passed by the camels again and again, as if they were just trying to cause the other party to panic.

And judging from the camel's helpless performance, this trick is quite effective, at least several times the camel tried to break out, but was forced back by several wolves.

"This is a common tactic of the wolf pack 'blitzkrieg'."

Bi Fang was a little excited, such a scene is rare.

"Look how clever they are, by constantly charging, trying to cut through the small family group of camels, and as soon as the cub is cut out, it will die!"

The size of the African wolf varies greatly from region to region, with West and North Africa being much larger than those in East Africa.

The country of the righteous man and gentleman is in West Africa, so these African wolves are not so small, and there are also some camels to set off, which makes the attack look even more aggressive.

The smallest camel is the weakest link in the small group, when it is still young, it has seen such a scene, and several times it can't help but run wildly, but it is firmly protected by two large camels, one left and one right, but the big camel is also uncomfortable.

They won't last long.
