The Sahara wolves that wandered around for a day and night were unbearably hungry, but when the subzero shrubs and weeds were removed, there was boundless loess. Apart from gnawing grass like fat lambs, the only thing they could do was dig through the soil to find beetles to eat.
.
During the day, the Sahara is as hot as a teppanyaki. Even the beetles are buried deep under the ground and are nowhere to be seen. When you dig up the soil, you only get the choking smoke.
Several secondary wolves stopped and raised their hind legs to itch. They bit the fur with their fangs, trying to drive away the damn fleas. Their sideways glances drifted towards the leading wolf from time to time, seeming to imply dissatisfaction, but hidden due to authority.
Not sent.
The alpha wolf is the strongest and most intimidating among the wolves. His body size alone is much larger than that of the other wolves, and he enjoys the service of the female wolf.
The itched hairs were flying in the air, wishing they could shed their fur and fall into a relaxed state, but thinking of the biting cold at night, the slightly loosened hair follicles took root firmly again.
It's hot during the day and freezing at night.
This is the Sahara.
Just as a few secondary wolves were at the end of the group, secretly expressing their dissatisfaction, a low wolf howl woke up the entire pack.
The pack of wolves in twos and threes immediately cheered up and quickly came to the head wolf, looking hard into the distance.
There were three camels, two big and one small.
There was not a tree for miles around, and the huge camel standing on the ground cast a shadow, making it particularly conspicuous.
Come to life.
Smoke and dust billowed, and the wolves charged towards the small camel family, their green eyes shining with hunger.
[This wolf is a bit small]
[Indeed, it seems much smaller than what Fang Shen encountered before]
【What kind of wolf is this, a desert wolf?】
The drone can automatically zoom in on the scene, making the two sides of the confrontation seem to be right in front of them, and the audience can see it more realistically.
The wolves surrounding the three camels were numerous in number, but their quality was inferior, and their bodies felt much smaller than those of the Arctic wolves.
Bi Fang himself was too far away, and there were not enough reference objects nearby. The only thing the audience could compare with was the besieged camel, so they were not sure whether the wolf was too small or the camel was too big.
Although the wolves were 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, it can create a certain degree of visual effect.
Think about meeting five dogs at home at once. Although the number is small, when you actually pounce on them, you will feel "there are so many" in your heart.
The increase in the number of animals is by no means just an increase in numbers. This is why Bi Xiang does not like to live in groups of carnivores, and it is always a troublesome thing to encounter them.
The large number of wild wolves made this charge seem huge and made people know that this small group of wolves should not be underestimated.
For this reason, Bi Fang did not approach rashly. After getting closer, he hid two hundred meters away, lying on the ground and watching the development of the situation. When he saw the barrage, he consciously started to explain the battle.
"That's a desert wolf, also called an African wolf. Your feeling is correct. They are indeed small, and much smaller."
"I have mentioned a Bergmann's law before, which means that for warm-blooded animals, among individuals of the same species or closely related species, those living in a cold environment will have a relatively larger body size."
"Bergman believes that this is because as the body size increases, the relative body surface area of the animal becomes smaller, resulting in a smaller body surface divergence ratio, so it can better conserve heat to adapt to the cold environment in high latitudes."
"This law is not a theorem, and it also has major flaws, but as far as mammals are concerned, more than 90% of species comply with it. So we can easily deduce that the closer to the equator, the smaller the body size.
The desert wolf is a typical example, they are not even half the weight of the Arctic wolf."
"Although the desert wolf is called a wolf, it is not a wolf in the strict sense, but an independent species in the genus Canidae."
Bi Fang lay on the loess and explained a little about the origin of the gray wolf, which also gave the audience a better understanding.
As a group predator, gray wolves are found almost all over the world, but they have disappeared only on the roads of Africa. The reasons for this are very complicated.
"In general, wolf is the name of gray wolf of the genus Canidae, and the migration route of the gray wolf's ancestors, including the gray wolf, has always been between Eurasia and North America, and has not entered Africa. The reason may be related to migration memory and
Environmental differences are related, which leads to the absence of gray wolves in Africa."
"Despite this, when canines migrated in the early days, some of them entered Africa, because there are still canids in Africa, and the African wolf is one of them."
【Then why is it called wolf】
[Maybe it’s due to language habits]
"It is indeed a language habit. For example, African hyenas, although they are called hyenas, are actually not canines. The hyenas under the feline suborder are neither cats nor canids, and are an independent species."
"This is all a matter of translation and naming. In the past, the translation and naming were not rigorous enough. The hyena looked like a dog at first glance, so people gave it a name with 'dog' in it.
There are still many similar historical issues, such as a cheetah is not a leopard, and a puma is not a lion. But these names have been widely used as official names, so the mistakes will be made without modification."
Precisely because they are not wolves, the habits of African wolves are slightly different from those of wolves, such as their flexible organizational form.
The social organization of African wolves is very flexible. The size of the group varies according to the available food. If there is enough food to eat, a large group can be formed. If there is no more food to eat, the number will disperse and become individuals again.
small group.
On the ground covered with coarse sand, African wolves charged at the camels over and over again, bringing up billowing smoke and dust.
The strange thing is that they are not in a hurry to launch an attack, but rely on the flexibility brought by their smaller bodies to pass by the camels again and again, as if they just want to cause the other side to panic.
And judging from the camel's helpless performance, this trick was quite effective. At least several times the camel tried to break out, but was forced back by a few wolves.
"This is a common tactic of the wolf pack called 'Blitzkrieg'."
Bi Fang was a little excited, such a scene was rare.
"Look at how smart they are. Through constant charging, they try to carve up this small family group of camels. As long as one of the cubs is cut out, it will be dead!"
The size of African wolves distributed in different regions varies greatly with geographical changes, and those in West Africa and North Africa are much larger than those in East Africa.
The land of gentlemen is in West Africa, so these African wolves are not that small, and they are also partially set off by camels, which makes this attack look more menacing.
The smallest camel is the weakest link in the small group. How has it ever seen such a scene at such a young age? It couldn't help but run away several times, but was firmly protected by two big camels on the left and right.
The big camel also felt uncomfortable.
They can't last much longer.
