When an animal is angry or afraid, its nervous system sends signals to these cells. Rage causes a dark color, excitement or fear – pale shades and yellow spots. Sunlight also affects the coloration of the chameleon. The hot sun makes the cells dark or even black. The high temperature without sunlight causes a green color, and in the dark the chameleon becomes creamy with yellow spots.
As you can see, factors such as emotions, temperature, light, and not the surrounding situation, cause the nervous system of the animal to change the state of colored cells.
But these changes in color help the chameleon and hide from their enemies, such as snakes and birds. And since the animal moves very slowly, it is a necessary form of protection to save one’s life.
Has the nature of the chameleon given the ability to automatically change its color from bright green to gray-black or yellow, depending on the surface on which it is located?
Strange as it may seem, the color does not depend on the environment! Chameleon simply does not pay any attention to this. The skin of the animal is transparent. Under it are black, red and yellow cells. When they shrink or expand, it seems that the chameleon changes its color.
