Lizards are a widespread group of squamate reptiles, with over 6,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic as it excludes the snakes and Amphisbaenia; some lizards are more closely related to these two excluded groups 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.
Podarcis is a genus of lizards in the family Lacertidae. Its members look very similar to lizards of the genus Lacerta, to which they were considered to belong until the 1970s. While similar externally and ecologically, Podarcis form a distinct group differing from Lacerta by the construction of the skull and the hemipenis, and by the processes of the caudal vertebrae. They are commonly known as wall lizards. They are native to Europe and northern Africa, and most species are restricted to the Mediterranean region. Wall lizards diversified and hybridized during the Messinian salinity crisis. The Italian wall lizard and the common wall lizard have been introduced to North America, where they have become intermediate hosts for some Acuariidae larvae.
The southern alligator lizard is a common species of lizard in the family Anguidae. The species is native to the Pacific coast of North America. It ranges from Baja California to the state of Washington and lives in a variety of habitats including grasslands, chaparral, forests, and even urban areas. In dry climates, it is likely to be found in moist areas or near streams. There are five recognized subspecies.
The slender glass lizard is a legless lizard in the Glass Lizard subfamily (Anguinae) The species is endemic to the United States. Two subspecies are recognized. The lizard was originally believed to be a subspecies of the eastern glass lizard. Their name comes from their easily broken tail which they can break off themselves without ever being touched. It is difficult to find a specimen with an undamaged tail. The lizard eats a variety of insects and small animals, including smaller lizards. Snakes and other animals are known to prey on the species. Humans have a part in destroying their environment and killing their food supply with insecticides. The lizard is considered to be a least-concern species according to the International Union for Conservation of Nature (IUCN), though it is vulnerable in Iowa and endangered in Wisconsin. It is important to note that the streamlined, legless species is often confused with snakes. Glass Lizards, however, differ from snakes as they possess a moveable eyelid, which is absent in snakes. Another way to distinguish glass lizards from snakes is the presence of an external ear opening, which are absent in snakes.
Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas. A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter. A robust species, up to 15 centimetres (5.9 in) long, its tubercules are enlarged and give the species a spiny armoured appearance.

Podarcis virescens, also known by its common name as Geniez's wall lizard, is a lizard species of the Lacertidae family. Podarcis virescens is commonly found in the Iberian Peninsula, including Spain and Portugal.

Colors vary during seasons and range between individuals from white, brown, green, and black.
