Polychrus acutirostris, the Brazilian bush anole, is a species of lizard native to southern and eastern Brazil, Paraguay, Argentina, and eastern Bolivia. [2] It is diurnal.
It is an oviparous animal with an arboreal habit, which inhabits a large part of South America. Its color becomes stronger during mating season, but it can also change to obtain better camouflage. Despite presenting several characteristics similar to those of "true chameleons", such as eyes that move independently and the ability to change color, the species does not belong to the same family as the Chameleon, but still has a level of kinship with the same, belonging to the same suborder: SauriaTheir diet basically consists of insects. The species is being threatened by habitat loss. With a calm temperament, it does not pose a danger to humans.
Another peculiar characteristic of the animal is the one that characterizes it by its popular name of "sloth lizard", its movements are slow, especially when compared to other reptiles that normally have agility in their locomotion. It tends to remain motionless most of the time to camouflage itself, which, along with its subtle ability to change color, is its greatest defenses. Its slow mobility, in addition to affecting its diet, makes it easy prey, possibly placing it in a group at risk of extinction.
A diurnal species, it usually lives in trees. The males of the species defend their territories. It is difficult to find, because of its ability to camouflage itself, being confused with the environment. Its reproduction is annual, females usually lay 7 to 31 eggs. To attract females, during the breeding season, males acquire a reddish color on their heads. It can be found in the Andes, from southern Pará to northern Argentina, in savanna formations.
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.
Chameleons or chamaeleons are a distinctive and highly specialized clade of Old World lizards with 200 species described as of June 2015. The members of this family are best known for their distinct range of colours, being capable of colour-shifting camouflage. The large number of species in the family exhibit considerable variability in their capacity to change colour. For some, it is more of a shift of brightness ; for others, a plethora of colour-combinations can be seen.
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.
The central bearded dragon, also known as the inland bearded dragon, is a species of agamid lizard found in a wide range of arid to semiarid regions of eastern and central Australia.
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 leopard gecko or common leopard gecko is a ground-dwelling gecko native to the rocky dry grassland and desert regions of Afghanistan, Iran, Pakistan, India, and Nepal. The leopard gecko has become a popular pet, and due to extensive captive breeding it is sometimes referred to as the first domesticated species of lizard but no lizards are actually domesticated.
The veiled chameleon is a species of chameleon native to the Arabian Peninsula in Yemen and Saudi Arabia. Other common names include cone-head chameleon, Yemen chameleon, and Yemeni chameleon. They are born pastel green and without their distinctive casques on their head. They grow this as well as become more colorful as they mature. They are known for their variable color changes due to a variety of factors, including to show aggression, social status, reproduction, and stress. Females live around five years and males live for around eight and they breed a few times a year.
The common basilisk is a species of lizard in the family Corytophanidae. The species is endemic to Central America and South America, where it is found near rivers and streams in rainforests. It is also known as the Jesus Christ lizard, Jesus lizard, South American Jesus lizard, or lagarto de Jesus Cristo for its ability to run on the surface of water.
Jackson's chameleon, also known as Jackson's horned chameleon, three-horned chameleon or Kikuyu three-horned chameleon, is a species of chameleon native to East Africa, and introduced to Hawaii, Florida, and California.
The Namaqua chameleon is a ground-living lizard found in the western desert regions of Namibia, South Africa and southern Angola.
The Cape dwarf chameleon is a chameleon native to the South African province of the Western Cape, where it is restricted to the region around Cape Town.
Varanus timorensis, the Timor monitor or spotted tree monitor, is a species of small monitor lizards native to the island of Timor and some adjacent islands.
The common chameleon or Mediterranean chameleon is a species of chameleon native to the Mediterranean Basin and parts surrounding the Red Sea. It is the only extant species of Chamaleonidae with a range that naturally extends into Europe.
The Angel Island chuckwalla, also known as the spiny chuckwalla, is a species of chuckwalla lizard belonging to the family Iguanidae endemic to Isla Ángel de la Guarda in the Gulf of California. The species was transported to other islands by a tribe of the Seri as a potential food source.
The San Esteban chuckwalla, also known as the piebald chuckwalla or pinto chuckwalla, is a species of chuckwalla belonging to the family Iguanidae endemic to San Esteban Island in the Gulf of California. It is the largest of the five species of chuckwallas, and the most threatened.
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.
Uracentron flaviceps, the tropical thornytail iguana or Amazon thornytail iguana is an elusive species of medium-sized arboreal lizard found in the tropical lowlands of the Amazon Rainforest. The species was described by French zoologist Alphone Guichenot in 1855. They are considered to be ant specialists and exhibit communal nesting and a harem-style breeding system in which one male mates with and attends to multiple females. Study of this species has been impeded by difficulties collecting and observing them.
Microlophus albemarlensis, the Galápagos Lava lizard, also known as the Albemarle Lava lizard, is a species of Lava lizard. It is endemic to the Galápagos Islands, where it occurs on several islands in the western archipelago: the large islands Isabela, Santa Cruz, Fernandina, Santiago and Santa Fe, as well as several smaller islands: Seymour, Baltra, Plaza Sur, Daphne Major and Rábida. It is the most widespread of the Galápagos species of Microlophus, the others only occurring on single islands. Some authors however, consider populations on Santiago, Santa Cruz, and Santa Fe to be distinct species. The species is commonly attributed to the genus Microlophus but has been historically placed in the genus Tropidurus.
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.
