Description

The Carolina anole can reach a total length of about 75 mm. Females are slightly smaller, about 55 mm. The male has a dewlap–pink or light red in color–that can be extended from the chin as a courtship or territorial display. This dewlap display is often accompanied by head bobbing and "pushups." Green Anoles can have a green or a brown body color, depending on mood, time of day, surroundings, and temperature, with a white underbelly.

Female Green (Carolina) Anole

It has often been claimed that the best way to tell a male from a female apart is through the white stripe along the backbone that most females exhibit. However, this is often a false judgment when trying to distinguish between the two sexes. Juvenile male adults often exhibit this feature well into early adulthood, and even some full-fledged male adults can still exhibit this white stripe. The only true way to determine the difference between a male and a female is a few subtle differences: the MATURE males will often be rather larger, and have larger, more prominent heads and snouts than the females, and of course exhibit a much larger dewlap. Also, adult males will exhibit another prominent feature seen only in the mature and sub adult males of the species, and that is a hemipenile bulge which one can see underneath the tail just below the vent. The females are often smaller, and with a head and snout more in proportion to the body, and can also exhibit dewlaps, but are often smaller and less frequently displayed/seen. However, it can be difficult at times to merely uses this as a means to tell the two sexes apart. The only true way to determine the sex of an anole, especially in juvenile specimens, is by the enlarged post-anal scales / pores located just beneath the vent and seen only in the male.

As the anoles age and grow, Anoles periodically shed their skin much as snakes and other reptiles do. Their eyes have a more vibrant ring of green or brown surrounding them depending on which color they are.

As a defense mechanism, their tails detach with mild force. The lost tail piece is left twitching as a distraction so the lizard may escape safely. Missing tails will regenerate, but the new tail is usually not as functional, and a lizard with a regenerated tail is usually distinguishable from a lizard with its original tail. Their eyes move independently of one another, as do those of chameleons.

Distribution

This species is native to North America, where it is found mainly in the southeastern parts of the continent. Anoles are most abundant on the coastal plain from North Carolina to Florida, and west into central Texas, at least as far as San Antonio. They have also been introduced into Hawaii. The species is also relatively popular as a pet. This and most other anole species are rarely bred in captivity, so most specimens sold in the pet trade are wild-caught. Babies are usually about the size of about a seven year old's thumb and should not be put in a tank that is over 10 gallons. When they hatch it is not uncommon for them to be eaten by the male.

Behavior

Anole licking

Anoles are, by their nature, curious creatures. A healthy lizard usually has a good awareness of its surroundings. The males are very territorial and will fight other males to defend territory. The stress caused by these encounters makes housing a pair of males together impossible. Stress in an anole can be identified by several symptoms. These symptoms include a constant shade of brown and a persistent black semi-circle behind their eyes. A stressed anole may also be lethargic. In a group of one male and several females some aggressive chasing may occur, but the encounters are short lived and less violent than between males. Anoles kept in groups like this need space and hiding places to be happy. 10 gallons of space minimum for each anole is a good rule to follow. During shedding an anole may use its mouth to pull the old skin off and will usually consume it. In addition to discarding their tails, anoles will attempt to bite perceived predators if cornered, which can be somewhat painful, but generally doesn't cause much harm other than some scratching of the bite area caused by the lizard's teeth. The anole will generally let go and attempt to flee if left alone, though will continue to maintain its grip with its jaws as long as a perceived attack (such as trying to pull the animal off) continues.

Breeding/Mating

Two Green Anoles Mating

The typical breeding season for green anoles begins from as early as April and ends to as late as August and even occassionally into September. It is during this time that the most brilliant displays of these creatures can be seen, as the males must court the females with their elaborate displays of extending their brightly colored dewlap while bobbing up and down, almost doing a dance for her while she runs in temptation from the young male. The pursuit will continue until the two successfully mate. Usually, when the female is ready to mate, she may let the male simply "catch" her and he will thus grasp a hold of a fold of her skin above her neck area, or she will bow her head before him and simply "let" him take his grasp. The mating then commences. Image File history File links Metadata No higher resolution available. ... Image File history File links Metadata No higher resolution available. ...

Anoles mating

After a 2-4 week span following conception, the female will lay her first clutch of eggs, usually ranging from 1-2 in the first clutch. She will continue to lay eggs during the season until a total of 10 or so eggs have been produced, up until she can produce no more, and so her gestation for the season has come to an end. When it comes time for her to lay her eggs, she will bury it in the soft soils or compost nearby, and after that she no longer takes any care for it. The egg(s) are left alone to incubate by the light of the sun and if successful will hatch in 35-40 or so days.

The hatchlings must fend for themselves, and they even must be awry of other adult anoles in the area, who could just see the newly hatched anole as another mid-day snack. Yet if the young anole survives and manages to escape the many predators that haunt its world, it too will one day become a beautiful full-fledged adult.


If the anoles are in captivity, however, for best results the eggs must be taken out of the adults' enclosure and incubated in moist, not wet, vermiculite at a temperature of around 85 degrees Farhenheit and around 70% humidity. The eggs will hatch within 35-40 or so days.


Once the eggs hatch, the young should be put into their own separate enclosure (separate from the adults), and the enclosure's temps and humidity levels should match that of the adult anoles. Hatchlings can be fed soft-shelled pinhead crickets, small leaf-hoppers, flightless fruit-flies, and other pesticide-free insects that do not exhibit a hard exoskeleton. The same goes true for adults as well. Pesticide-free insects are a must for anoles, so don't go for bugs in the area if you know that pesticides are sprayed or if you live in a rural area with lots of car exhaust and air pollution that can get on the insect.


Coloration and Color Morphs

A female green (carolina) anole

Generally, 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. There are a few exceptions, however, which are caused when a lack in one of the pigment genes occurs. There are 3 layers of pigment that make up the green anole color spectrum: the Xanthophores, responsible for the yellow pigmentation; Cyanophores, responsible for the blue pigmentation, and Melanophores, responsible for the brown and black pigmentation. The combination of the Xanthophores and Cyanophores are what make up the different arrays of green seen in the green anole, whereas the Melanophores are responsible for its change to brown when the anole is cold, stressed, or just needs to warm up for the day. When there is a lack of one of these pigments, color mutations, or also called "phases," can occur. In particular, this can lead to the incidence of the rare and beautiful blue-phased green anole, which lacks Xanthophores, or the yellow pigment that makes up the green hues of the green anole's color spectrum. What results is a blue, often baby or pastel blue, anole. These rare beauties have become a recent popularity in the trade market, yet are often sold for quite a hefty price due to their rarity. When the anole is completely lacking Xanthophores, however, it is said to be Axanthic. Such specimens are often completely pastel or baby-blue in hue. However, such specimens are extremely rare, usually produced in 1 out of every 20,000 individual anoles in the wild. Other color phases can also occur, such as the yellow-phased green anole, which lacks Cyanophores, which are responsible for the blue pigment in the green anole color spectrum. However, none are as popular or as brilliant as the blue-phased green anole. Colonies of these rare color-phased anoles have been reported, but anoles with these color mutations rarely live for long, since the green anole relies on its green and brown camouflage to hunt down prey as well as hide from predators.
