What type of chameleons change color

And why do they change colors? The ability to morph into your surroundings has been attempted by humans for years and often mimicked by hunters, military, and teenagers sneaking out of the house. But few have the abilities that our beloved chameleons possess. They don't have just one camouflage pattern, but they can change and adapt to their environments by utilizing their extremely special skin cells.

Television commercials, shows, and movies claim that chameleons can magically change their skin colors to match whatever they are standing on almost instantly. But while there is some truth to this magic, chameleons have limitations to the colors they can become and cannot match just anything. Greens and browns are the predominant colors of chameleons, and these shades help them camouflage into their environments. Black is another color that you will see on chameleons, especially on their throats, and some chameleons use this color to show they are threatened.

Some species of chameleons can turn more vibrant colors such as pink, red, blue, turquoise, or yellow. Panther chameleon and Madagascar chameleon species are some that are known to be extremely colorful and are also some of the most photographed kinds. Until recently, no one fully understood exactly how chameleons changed their colors. We now know that chameleons change their color by adjusting microscopic cells within their skin to reflect light differently.

These cells are called iridophore cells, and they contain tiny crystals called nanocrystals. Nanocrystals of different sizes that are arranged in different shapes and groupings cause light to be reflected in different ways making the skin of chameleons change colors, similar to how a crystal hanging in a window reflects the sunlight and shines a rainbow onto the wall. Chameleon skin is filled with these tiny crystals and when they move their skin by relaxing or tensing up their bodies the crystals shift and reflect light differently.

The skin cells also swell and shrink so that they move closer and farther apart. Thanks for stopping by Wonderopolis! Thanks for the feedback, Josh!

They filmed the chameleons' color changes using high-resolution videography and made numerical models that predict how the nanocrystals should reflect light. The researchers also manipulated the cells by subjecting them to solutions of varying concentrations, which caused the cells to swell or shrink. These modifications changed the distances between the nanocrystals, and altered their visible colors, just as the researchers predicted they would, Milinkovitch said.

However, only adult male chameleons change color, especially when they see a rival male chameleon they want to chase away, or a female to attract, Milinkovitch said. Females and young chameleons are dull-colored and have a very reduced upper layer of iridophore cells, he said. The findings may help engineers and physicists replicate the chameleon's color-changing capacities in new technology, such as appliances that eliminate reflection, Milinkovitch said.
