Agama (from Sranan Tongo meaning "lizard") is a genus of small-to-moderate-sized, long-tailed, insectivorous Old World lizards. The genus Agama includes at least 37 species in Africa, especially sub-Saharan Africa, where most regions are home to at least one species. Eurasian agamids are largely assigned to genus Laudakia . The various species differ in size, ranging from about 12 to 30 centimetres (5 to 12 in) in length, when fully grown.
Their colour also differs between species, between genders, and according to mood; for example, a dominant male in display mode is far brighter than when it has been caught, beaten by another male, or otherwise alarmed. Females tend to be less colourful than the males of the species.
According to species, agamas live in forest, in bush, among rocks and on crags, but where their habitat has been cleared, or simply occupied by humans, some species also adapt to life in villages and compounds, for example inside the thatch of huts and other sheltering crevices. Agamids' hind legs generally are long and powerful; and the lizards can run and leap swiftly when alarmed. [1]
Agamas are diurnal, active during the day. They can tolerate higher temperatures than most reptiles, but when temperatures approach 38 °C (100 °F) they generally shelter in the shade. Males frequently threaten each other by nodding, weaving, and displaying their brightest colours to establish dominance. If that is insufficient, they lash their tails and threaten each other with open jaws. The jaws are very powerful, and older males commonly have damaged tails as souvenirs of past combat. Females may sometimes chase and fight one another, and hatchlings mimic the adults' behaviour. [1]
Agamas are mainly insectivorous, hunting prey by sight and snatching it opportunistically. Their incisor-like front teeth and powerful jaws are adapted to dealing with quite large, hard prey. They also may eat eggs of other lizards, and sometimes feed on vegetable matter, such as suitable grass, berries, and seeds.
Though not formally polygamous, dominant males commonly accommodate several females at a time in their territory. During courtship, and also when asserting his territory, the male bobs his head in display; this gives rise to some of the common names, such as Afrikaans koggelmander (literally, "little mocking man"). Females occasionally initiate courtship by offering their hindquarters to the male and provoking him to catch her. Typically the breeding season is timed for eggs to be laid during the season after the rains. Eggs are laid in clutches of up to 12, depending on species and the size of the female. [1]
In the 10th edition of Systema Naturae of 1758, [2] Linnaeus used the name Agama (pg. 288) as the species Lacerta Agama (with Agama originally capitalized to indicate a name in apposition rather than a Latin adjective, which he would have made lowercase). His own earlier description from 1749 [3] was derived from Seba, [4] who described and illustrated a number of lizards as Salamandra amphibia and Salamandra Americana, said to resemble in some ways a chameleon lizard and that supposedly came (in error) from "America." Seba did not use the term "agama", however. Linnaeus repeated Seba's error in stating that the lizards lived in the Americas ["habitat in America"], and he included other types of lizards shown and mentioned by Seba under his species name Agama.
Daudin [5] later created the new genus, Agama, to incorporate various African and Asian lizards, as well as species from Mexico, the Caribbean, Central America, and South America. He noted that the name agama was used by inhabitants of Guiana for a species that he included in the genus Agama.
The word "agama" [6] has been traced to West African Gbe languages as a name for the chameleon. The word was brought to Dutch Guiana (modern Suriname) by imported West African slaves and was then used in local creole languages for types of local lizards. [7] Linnaeus may have taken the name "agama" from some unidentified source in the mistaken belief that the reptiles came from the Americas as indicated by Seba.
The name "agama" has no connection to either Greek agamos "unmarried" (as a supposed Latin feminine agama) or to Greek agamai "wonder" as sometimes suggested.
Because of the confusion over the actual taxon that was the basis for the name Agama agama, Wagner, et al. (2009) [8] designated a neotype (ZFMK 15222), using a previously described specimen from Cameroon in the collection of the Zoologisches Forschungsmuseum Alexander Koenig in Bonn.

Nota bene : A binomial authority in parentheses indicates that the species was originally described in a genus other than Agama.
Agamidae is a family of over 550 species of iguanian lizards indigenous to Africa, Asia, Australia, and a few in Southern Europe. Many species are commonly called dragons or dragon lizards.
Calotes is a genus of lizards in the draconine clade of the family Agamidae. The genus contains 29 species. Some species are known as forest lizards, others as "bloodsuckers" due to their red heads, and yet others as garden lizards. The genus name Calotes has been derived from the Greek word Καλότης (Kalótës), meaning ‘beauty’, referring to the beautiful pattern of this genus.
Ceratophora is a genus of agamid lizards found in Sri Lanka. The male has a horn on its snout.
Draco is a genus of agamid lizards that are also known as flying lizards, flying dragons or gliding lizards. These lizards are capable of gliding flight via membranes that may be extended to create wings (patagia), formed by an enlarged set of ribs. They are arboreal insectivores.
Laudakia is a genus of lizards, commonly known as Asian rock agamas, in the family Agamidae. The genus is found mostly in Asia, with some species in Southern Europe.
Pseudocalotes is a genus of lizards in the family Agamidae. The genus is endemic to Southeast Asia.
Euprepis is an obsolete genus of skinks in the subfamily Lygosominae. It was named by Wagler in 1830 and frequently used in subsequent years, often misspelled as Euprepes, a misspelling introduced by Wiegmann in 1834. It was then subsumed under the large skink genus Mabuya, until Mausfeld and others resurrected it for a group of mainly African skinks they split from Mabuya. The following year, Bauer argued that this assignment had been in error and that this group should be called Trachylepis instead. Euprepis itself is a junior synonym of Mabuya.
Lacerta is a genus of lizards of the family Lacertidae.
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.
The Nile monitor is a large member of the monitor family (Varanidae) found throughout most of Sub-Saharan Africa, particularly in drier regions, and along the Nile River and its tributaries in East Africa. Additionally, there are modern, invasive populations in North America. The population found in West African forests and savannahs is sometimes recognized as a separate species, the West African Nile monitor. While it is dwarfed by its larger relatives, such as the Komodo dragon, the Asian water monitor or the crocodile monitor, it is still one of the largest lizards in the world, reaching Australia’s perentie in size. Other common names include the African small-grain lizard, as well as iguana and various forms derived from it, such as guana, water leguaan or river leguaan.
The ocellated lizard or jewelled lizard is a species of lizard in the family Lacertidae. The species is endemic to southwestern Europe.
Laudakia stellio is a species of agamid lizard. also known as the starred agama or the roughtail rock agama.
The common agama, red-headed rock agama or rainbow agama is a species of lizard from the family Agamidae found in most of sub-Saharan Africa. To clear up centuries of historical confusion based on Linnaeus and other authors, Wagner et al. designated a neotype for the species, using a previously described specimen from Cameroon in the collection of the Zoologisches Forschungsmuseum Alexander Koenig in Bonn. The species name was formerly applied to a paraphyletic collection of taxa ; subsequent mitochondrial DNA analysis of various populations indicates they represent separate species. Consequently, three former subspecies A. a. africana, A. a. boensis, and A. a. mucosoensis are now considered separate species, and A. a. savattieri is considered synonymous with A. africana.
In the 10th edition of Systema Naturae, Carl Linnaeus described the Amphibia as:
Animals that are distinguished by a body cold and generally naked; stern and expressive countenance; harsh voice; mostly lurid color; filthy odor; a few are furnished with a horrid poison; all have cartilaginous bones, slow circulation, exquisite sight and hearing, large pulmonary vessels, lobate liver, oblong thick stomach, and cystic, hepatic, and pancreatic ducts: they are deficient in diaphragm, do not transpire (sweat), can live a long time without food, are tenatious of life, and have the power of reproducing parts which have been destroyed or lost; some undergo a metamorphosis; some cast (shed) their skin; some appear to live promiscuously on land or in the water, and some are torpid during the winter.
Bosc's fringe-toed lizard or Bosk's [sic] fringe-fingered lizard is a species of lizard in the family Lacertidae. The species is endemic to North Africa and Western Asia. Three subspecies are sometimes recognised; A. boskianus boskianus, from Lower Egypt; A. boskianus euphraticus from Iraq; and A. boskianus asper from the rest of the range; however this division is unsatisfactory because each subspecies has much variation and the differences between them are not consistent.
Agama bibronii, Bibron's agama or the North African rock agama, is a species of lizard belonging to the family Agamidae from north western Africa.
Agama hispida, also known commonly as the common spiny agama, the southern spiny agama, and the spiny ground agama, is a species of lizard in the family Agamidae. The species is native to southern Africa. There are two recognized subspecies.
