Â· 7 years ago. Chameleons camouflage themselves in a variety of different ways but most famously by changing the colour and pattern of their skin. Most chameleons can change colour and they do this by expanding or contracting cells in their skin that contain different pigments. They can blend into their surroundings by altering the colour of their skin to match the background. Chameleons will also use their ability to switch colour during social displays when they alter their colouration and pattern dramatically from the background. Their body shape also helps with camouflage as well as the way they move. The high arched back gives their body a leaf-like shape and their slow movements make it diffi cult for predators and prey to detect them. Some chameleons, for example the stump-tailed chameleon, rock back and forward to look like leaves being blown by the wind.
Chameleon skin has a superficial layer which contains pigments, and under the layer are cells with guanine crystals. Chameleons change color by changing the space between the guanine crystals, which changes the wavelength of light reflected off the crystals which changes the color of the skin. Color change in chameleons has functions in camouflage, but most commonly in social signaling and in reactions to temperature and other conditions. The relative importance of these functions varies with the circumstances, as well as the species. Color change signals a chameleon's physiological condition and ...
