Iguana (, Spanish: [iˈɣwana]) is a genus of herbivorous lizards that are native to tropical areas of Mexico, Central America, South America, and the Caribbean. The genus was first described by Austrian naturalist J.N. Laurenti in 1768. Two species are placed in the genus: The green iguana, which is widespread throughout its range and a popular pet; and the Lesser Antillean iguana, which is native to the Lesser Antilles. Genetic analysis indicates that the green iguana may comprise a complex of multiple species, some of which have been recently described, but the Reptile Database considers all of these as subspecies of the green iguana. The word "iguana" is derived from the original Taino name for the species, iwana. In addition to the two species in the genus Iguana, several other related genera in the same family have common names of the species including the word "iguana". The species is a popular quarry for pets, and non-native animals have been widely introduced beyond its native area, into Ishigaki Island, the Florida Peninsula, Hawaii, Singapore, Thailand, Taiwan, and including numerous islands with native Iguana populations in the Lesser Antilles.
