Green Hyena Lizard (definite introduction)
Chameleon is originally a common name for amphibious creepers. Its Chinese name is lizard, because this animal can change itself according to changes in the environment and changes in form. The skin color of the body is now used to ridicule people who have no attitude or principles, and to flatter people who take advantage of the situation. So what is the reason for the chameleon's changeable skin color?
1. Chameleons change their body color for the sake of exchange
Chameleons change their body color more for exchange, not just for disguise. Chameleons change colors by forming green, blue, yellow, red, brown, white or black. Contrary to popular belief, chameleons do not simply change their color in response to their surroundings, but use their body color to express their moods and styles, such as their willingness to mate.
2. Chameleon skin color changes according to temperature and emotion
Chameleons change skin color according to temperature, emotion and ultraviolet rays. These changes predict their social activities. and activity level play a key role. When female leopard chameleons (Panther Chameleon) are pregnant with offspring or want to tell males that they are not willing to mate, the orange pattern will turn into brown or black. They directly tell each other their own truth through body color.
3. The outer skin is transparent
The outer skin of the chameleon is transparent, and there are three layers of skin underneath, each layer has different cells. They contain pigments called chromoplasts, which give them the ability to change body color. The first layer includes red and yellow pigments called xantrophores; the second layer controls blue through guanophores; and the third layer includes melanophores with melanin.
4. Chameleons may turn yellow when angry
The epidermal cells of chameleons expand and break according to changes in external light and temperature and chemical reactions in the body. . For example, an angry chameleon may develop a yellowish color because when it is angry, its yellow cells explode.Stretch to block the blue light from the base layer.
5. The tail of the chameleon will be connected to the molt
The tail of the chameleon will be connected to the molt. A chameleon's skin does not grow, so it must shed its skin frequently. Baby chameleons shed their skin every few weeks, and adult chameleons molt approximately every four months.
Because chameleons have no outer and middle ears and no real facial expressions, people think that chameleons are actually deaf. They mainly communicate by shaking their bodies from a distance. In addition, chameleons can also determine the other person's mood by understanding the other person's skin color when interacting face-to-face. For example, the meaning of yellow is "Go away! I'm annoyed." We just think that chameleons' color-changing ability is awesome, but we may not realize that it has anything to do with expressing emotions.
