Agamidae, (order Squamata), lizard family composed of about 350 species in about 50 genera.
All rights reserved. Phylogenetically, they may be sister to the Iguanidae, and have a similar appearance. Aside from that, the appearance of agamids is highly diverse, ranging from the brightly colored species shown above to more "bland" species.
Several species of agamids have the ability to change their color, similar to a chameleon in that regard. There are both ground-dwelling and arboreal species. This feature is shared with the chameleons, but is otherwise unusual among lizards.
Many species are commonly called dragons or dragon lizards.
They are found over much of the Old World, including continental Africa, Australia, southern Asia, and sparsely in warmer regions of Europe.

[2][3] Many agamid species are capable of limited change of their colours to regulate their body temperature. Agamidae, (order Squamata), lizard family composed of about 350 species in about 50 genera. Agamids inhabit tropical rainforests and mountain forests as well as deserts and steppes throughout most of the Old World, but they are found primarily in Australia, southern Asia, and Africa. This list of agamid species is not all-inclusive, but includes many popular / well-known lizards found within the Agamidae family. The first comprehensive assessment was by Moody (1980)[12] followed by a more inclusive assessment by Frost and Etheridge (1989).

[4] In some species, males are more brightly coloured than females,[5] and colours play a part in signaling and reproductive behaviours. (2000)[15] and also by sampling across the Agamidae by Joger (1991). These differences in coloration are due in part to the variety of environments in which the agamid species live.
* Arranged alphabetically by common name. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. (2000)[14] and Honda et al. Knuckles Pygmy Lizard (Cophotis dumbara) is a agamid species endemic to Sri Lanka. Shared characteristics include well-developed limbs and strong tails.

Some, like the uromastyx, are excellent diggers and will scurry into their holes for safety.
This group of lizards includes some more popularly known, such as the domesticated bearded dragon, Chinese water dragon and Uromastyx species. This amazing photo was taken by a Wikipedia contributor. Agamids typically have scaly bodies, well-developed legs, and a moderately long tail; average body size ranges from 10 to 15 cm (4 to 6 inches), and the tail is 20 to 30 cm (8 to 12 inches) long, though the The agamids show a curious distribution.

Because of extensive propagation, its exact origin is uncertain although it probably came from Mexico. This species is probably the Agave most commonly grown as an ornamental plant, and has spread throughout the temperate and tropical areas of the world. The Agamidae Family of Lizards. They are, however, absent from Madagascar and the New World. Agamid lizards are generally diurnal, with good vision, and include a number of arboreal species, in addition to ground- and rock-dwellers. Other agamid species, like the aptly named hydrosaurus, have unique foot scales that allow them to run bipedally (on two legs) across water to escape predators. Agamids typically have scaly bodies, well-developed legs, and a moderately long tail; average body size ranges from 10 to 15 cm (4 to 6 inches), and the tail is 20 to 30 cm (8 to 12 inches) long, though the family varies widely. Contrary to an Acrodonta clade, some research suggests that Iguanidae sensu lato is paraphyletic with respect to Agamidae. [17], Among the Agamidae, six subfamilies are generally recognized:[18][19], The chameleons of the sister family Chamaeleonidae are sometimes discussed as subfamily Chamaeleoninae and subfamily Agaminae (referring to Agamidae, not the Agaminae mentioned above). The distribution is the opposite of that of the iguanids, which are found in just these areas but absent in areas where agamids are found. [6] Although agamids generally inhabit warm environments, ranging from hot deserts to tropical rainforests, at least one species, the mountain dragon, is found in cooler regions.
