Anole

Dactyloidae are a family of lizards commonly known as anoles (US: /əˈnoʊ.liz/ (About this soundlisten)) and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay.[1][2] Instead of treating it as a family, some authorities prefer to treat it as a subfamily, Dactyloidae, of the family Iguanidae.[3][4] In the past they were included in the family Polychrotidae together with Polychrus (bush anoles), but the latter genus is not closely related to the true anoles.[5][6] Anoles are small to fairly large lizards, typically green or brownish, but their color varies depending on species and many can also change it.[1][7] In most species at least the male has a dewlap, an often brightly colored flap of skin that extends from the throat/neck and is used in displays.[7] Anoles share several characteristics with geckos, including details of the foot structure (for climbing) and the ability to voluntarily break off the tail (to escape predators),[8][9][10] but they are only very distantly related, anoles being part of Iguania.[11][12] Anoles are active during the day and feed mostly on small animals such as insects, but some will also take fruits, flowers, and nectar.[7][13][14] They are fiercely territorial. After mating, the female lays an egg (occasionally two); in many species she may do so every few days or weeks.[7][8][15] The egg is typically placed on the ground, but in some species it is placed at higher levels.[7][16] Anoles are widely studied in fields such as ecology, behavior, and evolution,[7][17] and some species are commonly kept in captivity as pets.[18] Anoles can function as a biological pest control by eating insects that may harm humans or plants,[19] but represent a serious risk to small native animals and ecosystems if introduced to regions outside their home range.[20][21]
