Chameleon

The chameleon is a very well known species of lizard. They have long curly tail and large eyes. They are mostly found in forest parts of Africa and Asia. Some chameleons are able to change their color. 
Different chameleon species can change their color in patterns of pink, blue, red, orange, green, black, brown, light blue, yellow, turquoise, and purple. Chameleon skin has an outer layer which has pigment and under the layers are cell with guanine crystals. Chameleons can change their color by changing the amount of space between the crystals which then changes the wavelength of light reflected off the crystals, which changes the colors.
Color change in chameleons are to camouflage, but also commonly used in social signaling and in reactions to temperature and other conditions.Chameleons show brighter colors when are being dangerous to other chameleons,and darker colors when they give up.
 
A Chameleons feeding mechanism is very unique.They usually eat insects. They feed by projecting their long sticky from their mouth to the insect which a distance away. Tongue projection or shooting occurs in as low as 0.07 seconds.
