Iguana is an herbivorous genus of lizard native to tropical areas of Mexico, Central America and the Caribbean. The genus was first described in 1768 by Austrian naturalist Josephus Nicolaus Laurenti in his book Specimen Medicum, Exhibens Synopsin Reptilium Emendatam cum Experimentis circa Venena. Two species are included in the genus Iguana: the Green Iguana, which is widespread throughout its range and a popular pet, and the Lesser Antillean Iguana, which is endemic to the Lesser Antilles and endangered due to habitat destruction.
Alhough many different Iguanas are available as captives, they can be demanding to care for properly. Space requirements and the need for special lighting and heat can prove challenging to an amateur hobbyist. The Green Iguana or Common Iguana (Iguana iguana) is native to Central and South America and ranges over a large geographic area, from southern Brazil and Paraguay to as far north as Mexico and the Caribbean Islands. Currently there are nine described species and eight subspecies of Rock Iguanas of the genus Cyclura 0ccuring on islands in the West Indies, with a single species or subspecies restricted to individual islands.
