 CHAMELEONS

Chameleons are known for their rapid changing of colors. People believe that they change colors and camouflage against a background. But the truth is that they change color to regulate their temperatures or to communicate with other chameleons.

As chameleons cannot generate their own body heat, they change colors and adapt themselves to a favourable body temperature. For example, a chameleon might change into black color if it feels cold. Similarly a chameleon might turn light color to protect from sun’s heat.

Chameleons turn into bold colors to communicate with other chameleons. Males change into dark colors to express their anger. Whereas females change colors to let the males know that they are willing to mate. Owners of chameleons know the mood of their pets just by observing the changes in colors.

HOW DO THEY CHANGE COLORS

The outermost layer of their skin is so transparent. Under this skin there are certain cells called as Chromatophores. These chromatophores are filled with different pigments. The deepest layers contain cells called as melanophores , these are responsible for different color shades. The top layer iridophores are responsible for blue and light colors. On top of Idirophores there are two more cells known as xanthophores and erynthophores. These are responsible for yellow and red colors.

These pigments are filled in tiny sacs inside the cells and therefore they are responsible for all the color changes based on their mood. When the color changes the chromatophores are expanded.
