Polychrotidae is a family of lizards commonly known as Anoles. Some authorities (such as NCBI [[1]]) place the anoles in subfamily Polychrotinae of the family Iguanidae. Four genera are common: Anolis, Norops, Phenacosaurus and Polychrus. They are frequently and incorrectly called chameleons or geckos, although they are not biologically classified within or closely related to either of these groups. These misconceptions are likely due to their ability to alter their skin color and run up walls, respectively.

Overview

Anoles are small and common lizards that can be found throughout the southeastern United States, the Caribbean, and various other regions of the western world. A large majority of them sport a green coloration, including the only species native to North America, the aptly named Green anole, although the green anole can change its color based on its mood and surroundings. Anoles are an exorbitantly diverse and plentiful group of lizards. There are currently well over 300 known species. The knight, green, bark, and Cuban brown anoles can all be found in the United States, primarily in Florida, although the most prevalent of these species by far is the Cuban brown anole, which has pushed the native green (or "Carolina") anole population farther north. All species of anole in the U.S. except the green anole were introduced through eggs nested in imported plants. It is notable that while nearly all anoles can change their color, the extent and variations of this ability differ wildly throughout the individual anole species. For example, the green anole can change its color from a bright, leafy green to a dull brown color, while the Cuban brown can only change its shade of brown, along with the patterns on its back.

Many anoles are between 8 and 18 cm (3–7 inches) in length. Some larger species, such as the Knight Anole, can surpass 12 inches, some males of the Knight Anole species can even reach two feet.

Anoles thrive on live insects and other invertebrates with moths and spiders being some of the most commonly consumed prey. Anoles are opportunistic feeders, and may attempt to eat any attractive meal that is small enough. The primary food for captive anoles are small feeder crickets that can be purchased at most pet stores.

These subtropical lizards are semiarboreal. They usually inhabit regions around 3–6 m (10–20 feet) high. Shrubs, walls, fences, bushes, and short trees are common hiding places.

Most anoles are said to live between 3 and 5 years. Even anoles captured from the wild can live for several years if given acceptable living space and cared for properly—a healthy anole in captivity, being free from predators and natural disaster, may live well beyond seven years.

Breeding occurs for several months beginning in late spring. Males employ head bobbing and dewlap extension in courtship. 1–2 small, softshell eggs are laid among leaf litter. More clutches may be laid before mating season has ended.

Miscellaneous

Anoles have many features that make them readily identifiable. They have a dewlap, made of erectile cartilage, that extends from the neck/throat area. For example: If an intruder approaches, the male will compress its body, extend the dewlap, and bob its head. Their toes are covered with structures that allow them to cling to many different surfaces. Also, their tails have the ability to break off at special segments in order to escape predators or fights. The tail itself continues to wriggle strongly for some minutes after detaching. This ability is known as autotomy. Anoles are also diurnal, which means that they are active during the daytime.

Anoles, though defensive and territorial, are usually shy. They will often flee when faced with overwhelming danger. They are also very easily stressed. For these reasons, as well as others, it's highly recommended that any keeper avoid handling his anoles as much as possible.

Anoles, though relatively inexpensive themselves, are amazing lizards to keep and raise. They require somewhat intricate setups to mimic their subtropical habitats. It's often difficult for most people to imagine such a "cheap" lizard as being such a responsibility. This is why many pet anoles are considered to be neglected.
