When it comes to lizards, one of the most fascinating things about them is their ability to change colors. While not all lizards have this ability, many species do. In this article, we’ll take a closer look at which lizards can change colors, why they do it, and how it works.

Why Do Lizards Change Colors?
Lizards change colors for a variety of reasons. One of the most common is to regulate their body temperature. By changing color, lizards can absorb or reflect more heat from the sun, helping them to maintain their ideal body temperature.
Another reason lizards change colors is to communicate with other lizards. For example, male anoles will often change color to attract mates, while some species of chameleons will change color to signal aggression or submission to other members of their species.
Which Lizards Can Change Colors?
Not all lizards have the ability to change colors, but many do. Some of the most well-known color-changing lizards include:
Chameleons
Chameleons are perhaps the most famous color-changing lizards. They are able to change color by manipulating special pigment cells in their skin called chromatophores. By expanding or contracting these cells, chameleons can change the color and pattern of their skin.
Anoles
Anoles are small, arboreal lizards that are found throughout the Americas. Many species of anoles are able to change color, with males often changing color to attract mates or intimidate rivals.
Iguanas
While most species of iguanas are not able to change color, the green iguana is an exception. These lizards are able to change color from bright green to a duller brown or gray, depending on their mood and environment.
How Do Lizards Change Colors?
As mentioned earlier, lizards are able to change colors by manipulating pigment cells in their skin called chromatophores. These cells contain different pigments that can be expanded or contracted to change the color of the skin.
In addition to chromatophores, some lizards also have special cells in their skin called iridophores. These cells contain reflective crystals that can change the way light reflects off the lizard’s skin, creating a shimmering effect.
Conclusion
While not all lizards have the ability to change colors, many species do. Whether they’re changing color to regulate their body temperature, communicate with other lizards, or simply to blend in with their environment, color-changing lizards are a fascinating and unique part of the animal kingdom.
