Description: The green 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. Adult males within a population can be classified within a heavyweight and a lightweight morph. The male dewlap (throat fan) is three times the size of the female's and bright orange to pink, whereas that of the female is lighter in color. The dewlap is usually pink for Anolis carolinensis (more orange-red in A. sagrei) and is very rarely present in females. The color of the dewlap is variable and different from the lizard eye to the human eye. Green anoles are thought to be capable of seeing a larger range of the UV spectrum, and that the dewlap reflects ultraviolet light for attracting mates. Female anoles do, however, often have a dorsal line down their back. Extension of the dewlap from the throat is used for communication. Males can form a pronounced dorsal ridge behind the head when displaying or when under stress. Females and juveniles have a prominent white stripe running along their spine, a feature most males lack. Adult males are usually 4.9 to 8.0 inches long, with about 60-70% of which is made up of its tail, with a body length up to 3.0 inches and can weigh from 0.11 to 0.25 oz.

Habitat: A. carolinensis is arboreal in nature but may be seen on the ground and frequently seen on shrubs in the low country of the Carolinas. However, it can live in cities like Atlanta with little trouble so long as there is plentiful vegetation and bugs to eat. One can observe them on steps, trellises, and railings adjacent to foliage; on particularly hot summer days they may seek to cool off on indoor walls or on wrap around porches of older buildings, and in the former case can simply be captured in a shoebox and gently placed outdoors. It is common on roadsides, the edges of forests where there are shrubs and vines, but also construction sites having abundant foliage and sunlight. Their preferred habitat is open pine communities with a greater shrub density, it may harbor a greater abundance of anoles where they are able to watch for prey and intruders coming into their territory.

Range: This species is native to North America, where it is found mainly in the subtropical southeastern parts of the continent. Anoles are the most abundant on the Atlantic Coastal Plains in North Carolina, South Carolina, Georgia and Florida, and on the Gulf Coast in Alabama, Mississippi, Louisiana, and Texas, where they extend inland as far as Texas Hill Country and the DFW Metroplex; they have also been recorded in Tamaulipas, Mexico, but it is mostly likely an introduction. In the Carolinas, they are found on the coastal plains as far north as False Cape in Virginia, and in the southern piedmont of North Carolina, but throughout South Carolina, while in Georgia they are widespread except in the Blue Ridge region.

Diet: An anole's diet consists primarily of small insects such as crickets, grasshoppers, flies, butterflies, moths, cockroaches, small beetles, and other arthropods, including spiders, as well as occasionally feeding on various molluscs, grains, and seeds. Although anoles have been observed preying upon smaller reptiles such as juvenile skinks, this is not thought to be typical behavior. Many people who keep these lizards as pets feed them mealworms, grubs, maggots, and small crickets.

Reproduction: The typical breeding season for Carolina anoles starts as early as April and ends in late September, gonadal activity being largely regulated by photoperiod, enlarging in spring as the weather warms up and days lengthen, and then regressing in late summer.

During this time, the males patrol their territory and the most brilliant displays of these creatures can be seen. Males defend their territory and females from rivals, while courting the females with elaborate displays of extending their brightly colored dewlaps while bobbing up and down, almost doing a dance. The dewlap is also used to ward off other males. The male courts and pursues a female until the two successfully mate. Usually, when the female is ready to mate, she may let the male catch her, at which point he will grasp her by biting a fold of her skin behind her neck. The male will then position his tail underneath the female's tail near her vent. Males have two sex organs, known as hemipenes, which are normally kept within the body, but are everted from his vent for mating. Males seem to alternate between the left and right hemipenis on successive matings.

The female matures one ovarian follicle at a time, the ovaries alternating in production. The sight of a courting male induces ovarian development, sexual receptiveness and then ovulation. About two to four weeks following mating, the female lays her first clutch of eggs, usually one or two in the first clutch. She can produce an egg every two weeks during the breeding season, until about 10 eggs have been produced. However, she can store sperm for up to eight months following mating. She then buries the soft-shelled eggs in a shallow depression in soft soil, leaf litter, compost, rotting wood, or even a hole in a nearby tree. Eggs average 0.49 inches by 0.37 inches in size.

The eggs are left to incubate by the heat of the sun, and if successful, will hatch in about five to seven weeks (30–45 days) from late May to early October. The incubate temperature has to be 80 to 85 degrees Fahrenheit. On hatching, the hatchlings are 2.0 to 2.6 inches in length.

The hatchlings must fend for themselves, as they are not cared for by either parent. The young hatchlings must be wary of other adult anoles in the area, as well as larger reptiles and mammals, which could eat them. Younger anoles differ from adults in having less obvious head ridges, a wider head and shorter tail. They mature in about eight months.

Status: Although not threatened as a species, Carolina anoles increasingly struggle with competition from introduced anole species, such as the brown anole (Anolis sagrei), also known as the Bahamian anole. This competition happened to be an interesting model for evolutionary studies, as it illustrates the process of adaptation. When A. sagrei first appeared in the United States in the early 1900s, the Carolina anole mostly ceded ground-level territories and were relegated to a very different ecosystem high in the treetops. On occasion, more aggressive Carolina anole individuals may still be seen closer to the ground. Currently, A. carolinensis is abundant in its area of distribution and is able to thrive in disturbed areas, so it is not considered threatened, but A. sagrei may represent a developing threat in some areas.
