The Carolina anole (Anolis carolinensis) is an arboreal lizard found primarily in the southeastern United States and some Caribbean islands. Other common names include the American green anole, American anole, and red-throated anole. It is also sometimes referred to as the American chameleon due to its ability to change color from several brown hues to bright green and its somewhat similar appearance (though it is not a true chameleon).
The Carolina anole is a small to medium-sized lizard, with a slender body. The head is long and pointed with ridges between the eyes and nostrils, and smaller ones on the top of the head. The toes have adhesive pads to facilitate climbing. They exhibit sexual dimorphism, the males being fifteen percent larger. The male dewlap (throat fan) is three times the size of the female's and red, whereas that of the female is white.
Adult males are usually 12.5–20.3 cm (4.9–8.0 in) long, with about 60-70% of which is made up of its tail, with a body length up to 7.5 cm (3.0 in) and can weigh from 3–7 g (0.11–0.25 oz).
Colour varies from brown to green and can be changed like many other kinds of lizards, but anoles are closely related to iguanas and are not true chameleons. Although A. carolinensis is sometimes called an 'American chameleon', true chameleons do not naturally occur in the Americas, and A. carolinensis is not the only lizard currently in its area of distribution capable of changing colour. In contrast, many species of true chameleons display a greater range of color adaptation, though some can hardly change color at all.
The typical coloration for a green anole ranges from the richest and brightest of greens to the darkest of browns, with little variation in between. The color spectrum is a result of three layers of pigment cells or chromatophores: the xanthophores, responsible for the yellow pigmentation; cyanophores, responsible for the blue pigmentation, and melanophores, responsible for the brown and black pigmentation when the background is other than green and the anole changes color to camouflage itself. The anole changes its colors whether cold or hot or by mood. The bright light, against foliage, it appears emerald in colour, but in shadier, cool or moist conditions grey to olive brown. However the color change is not simply a matter of matching background, but rather body temperature, stress and activity. Green reflects activity and bright light, whereas brown reflects reduced activity in moist, dark cool conditions.
