Anolis carolinensis or green anole is a tree-dwelling species of anole lizard native to the southeastern United States and introduced to islands in the Pacific and Caribbean. A small to medium-sized lizard, the green anole can change its color to several shades from brown to green.
Common names include the Carolina anole, American green anole, American anole, and red-throated anole. It is also sometimes referred to as the American chameleon (typically in the pet trade) due to its color-changing ability, however it is not a true chameleon.
