Teiidae is a family of autarchoglossan lizards native to the Americas. Members of this family are generally known as whiptails or racerunners; however, tegus also belong to this family. Teiidae is sister to the Gymnopthalmidae, and both families comprise the Teiioidea. The Teiidae includes several parthenogenic species – a mode of clonal reproduction. Presently, the Teiidae consists of approximately 150 species in eighteen genera.
Meroles is a genus of lizards, commonly known as desert lizards, in the family Lacertidae. The genus contains eight species, inhabiting southwestern Africa, especially the Namib Desert.
Crocodilurus is a monotypic lizard genus consisting of one species, the crocodile tegu, belonging to the family Teiidae. Its common name is the 'crocodile' tegu, due to its appearance and fondness for water, and is locally known as the jacarerana. This semi-aquatic, predatory lizard has a flattened, paddle-like tail, enabling it to swim with ease.
The genus Dracaena, also called caiman lizards or water tegus, is in the teiid family, along with tegus and ameivas. Caiman lizards are found in South America in Ecuador, Colombia, Paraguay, Peru and Brazil. These semiaquatic lizards spend a lot of time in the water and inhabit marshes, streams and flooded forests. Caiman lizards often bask on branches overhanging the water.
