The Chameleon – गिरगिट

    Chameleons
Someone could be excused for thinking that when God designed Chameleons he was in a very creative and imaginative mood, or that he assembled them from spare parts that didn't fit easily into the rest of his creation.

                                                                                                                                        
             

Chameleon a lizard which changes colour always attracted mankind . Chameleon means ‘Earth Lion’.   In the morning they squeeze their sides together and puff out their chins, flattening their bodies to create more surface area. Dark colors absorb heat better, so the side of the chameleon facing the sun becomes almost black, while the other remains it usual color !
                                                                                 
There are more than 100 types of chameleons.
Most change from brown to green and back. 

A change can occur in 20 seconds! How does this color "magic" happen?




                                                                                                                           

Chameleons are born with special cells that have a color, or pigment, in them. These cells lie in layers under the chameleon's outer skin. They are called chromatophores (kro MAT uh fors). The top layers of chromatophores have red or yellow pigment. The lower layers have blue or white pigment. When these pigment cells change, the chameleon's skin color changes.
                   
               

Many people think chameleons change color to blend in with their surroundings. Scientists disagree. Their studies show that light, temperature, and mood cause chameleons to change color. Sometimes changing color can make the chameleon more comfortable. Sometimes it helps the animal communicate with other chameleons.
