Lizard is the common name used for all squamate reptiles other than snakes, encompassing over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The grouping is paraphyletic as some lizards are more closely related to snakes than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon.
Dactyloidae are a family of lizards commonly known as anoles and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay. Instead of treating it as a family, some authorities prefer to treat it as a subfamily, Dactyloinae, of the family Iguanidae. In the past they were included in the family Polychrotidae together with Polychrus, but the latter genus is not closely related to the true anoles.
Anolis is a genus of anoles, iguanian lizards in the family Dactyloidae, native to the Americas. With more than 425 species, it represents the world's most species-rich amniote tetrapod genus, although many of these have been proposed to be moved to other genera, in which case only about 45 Anolis species remain. Previously, it was classified under the family Polychrotidae that contained all the anoles, as well as Polychrus, but recent studies place it in the Dactyloidae.
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 is a trunk-crown ecomorph and can change its color to several shades from brown to green.
The brown anole, also known commonly as the Cuban brown anole, or De la Sagra's anole, is a species of lizard in the family Dactyloidae. The species is native to Cuba and the Bahamas. It has been widely introduced elsewhere, via the importation and exportation of plants where the anole would lay eggs in the soil of the pots, and is now found in Florida and other regions of the United States including southern Georgia, Texas, Louisiana, Tennessee, Mississippi, Alabama, Hawaii, and Southern California. It has also been introduced to other Caribbean islands, Mexico, and Taiwan.
The common collared lizard, also commonly called eastern collared lizard, Oklahoma collared lizard, yellow-headed collared lizard, and collared lizard, is a North American species of lizard in the family Crotaphytidae. The common name "collared lizard" comes from the lizard's distinct coloration, which includes bands of black around the neck and shoulders that look like a collar. Males can be very colorful, with blue green bodies, yellow stripes on the tail and back, and yellow orange throats. There are five recognized subspecies.
The knight anole is the largest species of anole in the Dactyloidae family. Other common names include Cuban knight anole or Cuban giant anole, highlighting its native country, but it has also been introduced to Florida. In its native Cuba, this large anole is called chupacocote.
Anolis pulchellus, the Puerto Rican anole, Puerto Rican bush anole, snake anole, or sharp-mouthed lizard, is a small species of anole lizard in the family Dactyloidae. The species is among the most common lizards in Puerto Rico, and also native to Vieques, Culebra, and the Virgin Islands.
Anolis cristatellus is a small species of anole, belonging to the Dactyloidae family of reptiles. The species is native to Puerto Rico and the U.S. and British Virgin Islands, with introduced populations in locations around the Caribbean. The males of A. cristatellus are easily recognizable by the fin running down the top of the tail, which is known as a "caudal crest". The females also have this crest, but it is smaller than that of the males. The species is often quite common in many areas on Puerto Rico, where it can be seen during the day passing the time on the lower parts of tree trunks, or on fences and the walls of buildings in urban areas, sometimes venturing down onto the ground in order to lay eggs, have a snack, or do other cursorial activities. Like many anoles, this species displays the characteristic behaviour of doing push-ups as well as inflating a pizza-like flap of coloured skin on its throat, known as a dewlap, in order to show others how dominant it is, and thus attract mates or intimidate rivals.
The Puerto Rican twig anole or dwarf anole is a species of small, arboreal anole endemic to Puerto Rico and primarily inhabiting the Cordillera Central from the Sierra de Cayey range in the Southeast to the central-western ranges of Maricao. A mostly grey to olive-brown bodied lizard, A. occultus is the smallest of the Puerto Rican anoles with a snout to vent length of 34–42 mm. In comparison to other twig anoles, A. occultus is extremely cryptic through its unique sleeping behaviors and mottled pattern. Sleeping behavior including site selection minimizes the probability of predator encounter along with A. occultus' extensive list of antipredator behaviors.
Anolis oculatus, the Dominica anole, Dominican anole, eyed anole or zandoli, is a species of anole lizard. It is endemic to the Caribbean island of Dominica, where it is found in most environments. The species is found in a diverse range of color forms, which one herpetologist once classified as four subspecies, which most other scientists did not recognise because the forms gradually inter-grade with one another. Two later researchers have instead promoted the "ecotypes" concept, hypothesizing the color forms are maintained by the ecological conditions of the surrounding environment, despite being genetically indistinguishable. The morphology of some traits is subject to clinal variation, gradually changing from one side of the island to the other, or from sea level to the hilltops. The ground color ranges from pale tan or yellow to deep green or brown. It also has patterned markings that range from light-colored speckling to complex marbled patterns, and some populations also have large black-ringed "eye" spots on their flanks.
Sphaerodactylus macrolepis, also known as the big-scaled dwarf gecko or the big-scaled least gecko, is a lizard of the Sphaerodactylus genus. It was first documented in 1859 in the US Virgin Islands, specifically, St. Croix. This diurnal species has since been spotted in other locations such as Puerto Rico with major populations in Culebra.
Anolis agassizi, Agassiz's anole, is a species of lizard in the family Dactyloidae. The species is endemic to Malpelo Island, which is part of Colombia.
Anolis grahami, commonly known as the Jamaican turquoise anole and Graham's anole, is a species of lizard in the family Dactyloidae. The species is native to the island of Jamaica, and has also been introduced to the territory of Bermuda. It is one of many different species of anole lizards found in Jamaica. There are two recognized subspecies.
Anolis cuvieri is a species of lizard in the family Dactyloidae. The species is endemic to Puerto Rico, and is common in the Toro Negro State Forest.
Lizards are among the most diverse groups of reptiles, with more than 5,600 species. With such diversity in physical and behavioral traits, lizards have evolved many ways to communicate. Communication may be physical, chemical, tactile, or vocal, and varies according to habitat, sexual selection practices, and predator avoidance methods. Each type of communication uses different sensory systems, including visual, olfactory, and auditory.
Anolis stratulus is a moderately-sized species of anole found in Puerto Rico, the United States Virgin Islands and the British Virgin Islands. It is a gray-colored lizard spotted with brown markings. It is arboreal, usually found positioned on tree bark on branches in the canopies of forest trees, where in some areas of Puerto Rico it can be incredibly abundant, with tens of thousands of the lizards being present per hectare.
Anolis aquaticus, commonly known as the water anole, is a semi-aquatic species of anole, a lizard in the family Dactyloidae, native to southwestern Costa Rica and far southwestern Panama. The species demonstrates adaptations that allows it to spend periods of time underwater up to approximately a quarter of an hour, forming an air bubble which clings to its head and serves to recycle the animal's air supply while it spends time beneath the surface. Although highly unusual, similar adaptions and behavior are found in other species of semi-aquatic anoles.
Anolis auratus, the grass anole, is a species of lizard in the family Dactyloidae. The species is found in Costa Rica, Panama, Venezuela, Colombia, French Guiana, Guyana, and Brazil.
Anolis evermanni, also known commonly as the emerald anole, Evermann's anole, and the small green anole, is a species of lizard included within the family Dactyloidae. A. evermanni is native to Puerto Rico, where it is mainly found in wet forests. A. evermanni is a medium-sized lizard and bright emerald-green in color. A. evermanni is studied for its behavior as well as the evolution of the family Dactyloidae. The group of lizards which are member species of the family Dactyloidae are known as anoles. Anoles are found throughout the Americas and are related to iguanas.
