Madagascar is home to about half the world's 150 or so species of chameleons including both subfamilies, typical chameleons (Chamaeleoninae) and dwarf chameleons (Brookesiinae).

Chameleons are small to mid-size reptiles that are famous for their ability to dramatically change colors (how?). Contrary to popular belief, a chameleon typically does not change colors to match its surroundings. Instead color is usually used to convey emotions, defend territories, and communicate with mates.

Other easily noted characteristics of chameleons include bulging eyes that move independently of one another, feet fixed in a grasping position, and the existence of horns or crests on the heads of many species. Additionally arboreal species have prehensile tails used for grasping objects when climbing and moving. Finally some species long extensile tongues for catching insects or small vertebrates at a distance sometimes greater than the length of the chameleon.

Chameleons are diurnal, solitary, and often aggressive towards members of their own species (marked by rapid color change and aggressive posturing). They are opportunistic hunters that wait for prey to pass within range of their long tongues. Chameleons have a bizarre way of moving where they slowly rock back and forth between each step taken, often in time with the movement of nearby leaves being blown by the wind. Most chameleons lay eggs.

More from Wikipedia.org:

Chameleons (family Chamaeleonidae) are small to mid-size reptiles that belong to one of the best known lizard families. They are famous for their ability to change their colour, and also because of their elongated tongue and their eyes which can be moved independently of each other. The name "Chameleon" means "earth lion" and is derived from the Greek words chamai (on the ground, on the earth) and leon (lion).

Distribution and habitat:

The main distribution of Chameleons is Africa and Madagascar, although some species are also found in parts of southern Europe, Sri Lanka, India and Asia Minor. Different members of this family inhabit all kinds of biotopes like tropical and montane rain forests, savannahs and sometimes semideserts and steppes. Chameleons are mostly arboreal and are often found on smaller bushes and shrubs rather than on taller trees. Some species, however, live on the ground under foliage.

Behaviour:

All Chameleon species are diurnal. Their main activity is in the morning and in the evening. Chameleons are not active hunters but rather sit motionless for hours and wait for a prey to pass by. They mainly feed on different arthropods and small vertebrates. Chameleons live mostly solitary and are quite aggressive toward other members of the same species.

Change of color:

Some Chameleon species are able to change their body color, which has made them one of the most famous lizard families. Contrary to popular belief, this change of color is not only an adaptation to the surroundings but also an expression of the physical and physiological condition of the lizard. The skin color is changed under influence of mood, light and temperature. The skin color also plays an important part in communication and rivalry fights.

Chameleons have specialized cells that lie in two layers under the chameleon's transparent outer skin. The cells in the upper layer, which are called chromatophores, contain yellow and red pigments. Below these chromatophores is a another cell layer. Cells of this layer are called guanophores and they contain the colorless crystaline substance guanin. These guanophores reflect amongst others the blue part of incident light. If the upper layer of chromatophores is yellow, the reflected light becomes green (blue plus yellow). A layer of dark melanin containing melanophores is situated even deeper under these blue and white light reflecting guanophores.These melanophores influence the lightness of the reflected light. All these different pigment cells can relocate their pigments, thereby influencing the color of light which is reflected.
