Did you ever just wish you could blend into the background? Perhaps you forgot to read all of your homework assignment and the teacher calls on you. Wouldn’t it be great if you could make yourself look like a desk and chair?
Chameleons are lizards that are part of the scientific family called Chamaeleonidae. In addition to the ability to change color, chameleons have many other characteristics that make them special, including parrot-like feet, eyes that can look in two different directions at once and long tongues and tails.
Chameleons come in many colors, such as pink, blue, orange, red, yellow, green and turquoise. They can be found in Africa, Europe, Asia and North America. There are about 160 different species of chameleons, and they can live in both rain forests and deserts.
Many people believe chameleons change colors to disguise themselves and hide from predators. However, chameleons are very fast — many can run up to 21 miles per hour — and can avoid most predators quite easily. Camouflage is thus only a secondary reason why most chameleons change color.
So why would they want to change colors? Scientists believe that chameleons change color to reflect their moods. By doing so, they send signals to other chameleons. For example, darker colors tend to mean a chameleon is angry. Lighter colors might be used to attract mates.
Some chameleons also change colors to help their bodies adjust to changes in temperature or light. For example, a chameleon that gets cold might change to a darker color to absorb more heat and warm its body.
Chameleons change their color by manipulating specialized cells — called chromatophores — that contain different colors of pigment. When a chameleon wants to convey a particular mood or message, its brain sends a message to its chromatophores, which then move pigments around to change the chameleon’s color.
