Everything in the living room quickly became taller, and Shen Fei was automatically switched back to chameleon mode.

This kind of automatic switching, which he can't control, has always made him puzzled, and he always feels like there is a layer of window paper that can't be touched, and he doesn't know where to go if he wants to poke it open.

Although this dream was full of dangers, it also allowed him to experience more magic, and he had the feeling that he could do whatever he wanted in other people's dreams, and it was difficult to get excited.

However, as a result of successfully getting out of danger, I was mentally relaxed, and a sense of fatigue naturally set in.

Du Meng really hadn't finished the transaction yet, and Shen Fei felt even more at ease, mentally more relaxed, and felt that it would definitely be beautiful to sleep now.

As he walked forward, Erqin and Honeypot retreated one after another, and even Amy seemed to be a little afraid, Shen Fei guessed that they had all seen him use five green tree pythons to deal with the salesman before he came out of his dream. Although the green tree python did not pass through its own hands, in that case, as long as you have a little bit of intelligence, you will guess that it has something to do with you.

But it is obvious that the little dumplings do not have that IQ, and they think they are the air force special forces who are erratic, and they swoop and tease Shen Fei from time to time, and Shen Fei is too lazy to pay attention to these little guys now.

Shen Fei estimated that Amy, Erqin, and Honeypot couldn't see the salesperson's dream within a dream, otherwise they might be scared by themselves.

Suddenly darkened behind him, Shen Fei subconsciously rolled his eyes to look behind him, the dream projection had disappeared, and it was estimated that the perverted salesman was either killed by the green tree python in the dream, or was scared awake.

Shen Fei yawned, I won't play with you anymore, Ben Long is going to rest in peace......

When he woke up, Shen Fei felt that something was not quite right on his body, and after a closer look, he found that he was about to molt again.

He thought back for a while, when Dumont first started, he said that he had to molt once a week or two to two or three weeks, because he was still young at that time, and it was the time to grow his body, and his metabolism was very vigorous. After that, the molting cycle will become longer and longer, and when you reach adulthood, you will only molt once every four months. So how long is the interval this time? What is the date of the month? Why don't you remember? Is it because as a chameleon you don't have to pay attention to date changes?

He finished molting in less than an hour, but he was stunned by the color on his body, and just now, it seems, probably, as if he had seen the color change?

He hadn't paid much attention to how and why chameleons changed color before, and when he was a child, his textbooks said that chameleons changed color to adapt to the environment. By changing color, the chameleon blends in with the background and is used to avoid predators or approach prey. As long as the knowledge of animal camouflage and color protection is mentioned in popular science books and TV shows, the chameleon will inevitably appear as an honorary guest.

But he recently learned from newspapers and the Internet that that knowledge has long since become obsolete. While it is true that some chameleons have a predominantly concealed color, they do not change color to avoid predators or get close to their prey, and it is impossible for them to quickly and accurately switch their body color according to changes in their environment.

The videos of chameleons changing color as they walk, such as when passing by a pair of brightly colored glasses that have been deliberately placed, or when using a row of tablets to switch between rainbow-like desktops on the fly, the chameleon changes color in seconds, showing the magic of blending into the background as much as possible.

In fact, it was all post-processed, and in this era when a three-hundred-pound aunt can become an awl-faced Internet celebrity, it is not too difficult to make a video of a chameleon changing color while walking.

Research has now proven that chameleons change their body color for two main reasons.

The first reason is to act as a tool for information exchange, to express one's emotions and intentions. Chameleons are unable to make complex sounds like humans, so they express their joys, sorrows, and sorrows through body language such as body color.

For example, when courting a chameleon, especially when there are competitors, the male becomes particularly showy and fierce like a well-known bird, so as to have a chance to capture the heart of the chameleon.

Scientific studies have shown that whether it is a girl grabbing a girl or fighting for territory, the brighter the color of the chameleon, the more likely it is to win in the struggle, and the specific reasons have not yet been determined.

Don't think that the girl chameleon is confused by the bright colors of the male, it is a demonstration of its own strength.

No matter what kind of animal it is, if you want to make your color outstanding, you must first ensure adequate nutrition, just like people, nutrition can't keep up, and there are few good-looking faces.

Therefore, the choice of a colorful male by the sister chameleon is equivalent to choosing a good breed with excellent physical fitness, which can ensure that the offspring are healthier.

Because sister chameleons and juvenile chameleons don't have to stage a plot to grab girls for territory, their body color is far less gorgeous than that of adult male chameleons.

Shen Fei suddenly felt that the more brightly colored the chameleon, the more likely it was to win in the struggle, and the puzzle was not difficult to solve. When males use competition to demonstrate, it is also equivalent to conveying the message that they eat well and are in good health, so the chameleon who can't keep up with nutrition is scared from the heart, and the fighting spirit is absolutely affected, and if he loses first psychologically, can he still hope to achieve the final victory?

The second major reason chameleons change their body color is regulating their body temperature.

As a cold-blooded animal, the chameleon does not have the same adjustment mechanism as an endothermic animal, but it can regulate its body temperature by changing the color of its body surface to achieve a purpose similar to that of dark colors that can absorb heat and light colors that can reflect sunlight.

The chameleon's skin contains two layers of densely overlapping iridescent cells, which contain not only pigment but also countless nanocrystalline structures, also known as photonic crystals, which reflect light and emit a rainbow of shining colors.

Differences in the size, shape, and arrangement of photonic crystals can change the chameleon's body color. Chameleons control the arrangement of these crystals through the relaxation and tightening of the skin, resulting in body color changes.

When the chameleon is in a calm state, these crystals are arranged in a tight manner, and when light passes through these cells, it allows people to see short-wavelength green light, blue light, and so on. When the chameleon is in a tense state, the density of the crystals is loosely arranged, and the voids are increased, which will make people see yellow, orange, red and other colors with longer wavelengths.

The lower layer of iridescent cells does not have the function of changing color, and its function is to regulate temperature. Just like changing color, chameleons can instantly change their ability to absorb heat by adjusting this layer of cells. Scientists are studying bionic heat-absorbing and heat-insulating materials based on this principle.

Shen Fei didn't do anything else this day, and was busy researching the secret of his discoloration.

He found that in most cases, the color change is mainly based on the brightness and darkness of the color, and changes according to his mood, the light of the environment, the temperature, etc.

When you deliberately excite yourself, your body color can appear in bright colors such as magenta, royal blue, bright yellow, and emerald green.

When resting quietly, the body color changes to dark red, gray blue, earthy yellow, light green, and other colors.

But when he got angry because of Erqin's jumping around, his body color turned all black!

He immediately launched a targeted experiment, and the results surprised him to be able to turn into red, orange, yellow, green, cyan, blue, and purple monochromes!

You can also change different levels of color according to different backgrounds, and perfectly camouflage yourself, which is equivalent to invisibility!
