Introduction: It has always been thought that chameleons will paint pigments all over their bodies to change their colors. However, the latest research shows that chameleon displays the color of the whole visible spectrum by adjusting the nanocrystals in the skin, which leads to light diffraction and discoloration.

First, what is a chameleon? The chameleon originated in Africa and is a cold-blooded animal whose main food is insects. The chameleon is a fickle arboreal reptile. In essence, it is a "master of disguise". In order to avoid the invasion of natural enemies and get close to prey, this reptile often inadvertently changes its body color and then puts itself in the surrounding environment. They are lizards that live in trees. Most of them are only 20 cm to 30 cm long, and the largest chameleon is no more than 60 cm long. Chameleons crawl very slowly. It often takes the first step today and continues to take the second step the next day. Interestingly, the slow chameleon actually uses jumping insects as its own food.

Second, the reason why the chameleon changes color is that the chameleon can change color because there are seven kinds of color-changing cells in its skin tissue. In this way, it can change its color and disguise itself with the change of environment and environmental factors such as light intensity and temperature, so as to capture food more safely and easily. Chameleons change the color of their bodies, which is a way to protect themselves. When in danger, it will turn into the same color as the surrounding trees, grass, bark, etc., making it difficult for the enemy to find himself. According to the latest findings of animal experts, the chameleon changes its body color not only for camouflage, but also for changing its body color. Another important function is to realize the information transmission between chameleons, which is convenient for communication with companions, equivalent to human language, thus expressing the intention of chameleons.

Therefore, in order to show his dominance over the territory, the male chameleon showed a bright color in the face of similar demonstrations invading the territory. When it meets a suitor it doesn't like, the female chameleon will refuse, and then the body color will become dim and show flashing red spots. In addition, when the chameleon wants to provoke disputes and attacks, the body color will become very black.
