Iguanas are naturally found in Mexico and the Central and Southern part of the Americas and some are found in the Lesser Antilles Islands, Hawaii, Florida and California.

These are the types of iguanas found within the Iguanidae family:

Genus Cyrclura or rock iguana can be found in most of the Caribbean Islands. They are an endangered species so they are rarely sold or traded, but if ever you find one in a shop it was most probably bred in captivity.

Genus Amblyrhyncus is known as the marine iguana or the Galapagos Marine Iguana. They are the most difficult to keep as pets because their diet of marine algae is close to impossible to produce commercially.

Genus Conolophus are the closest relatives of the marine iguana. This type of iguana is also called the Galapagos Land Iguana and basically they feed on plants and cactus.

Genus Ctenosauria or spiny-tailed iguanas are native to Mexico and Central America. They are small compared to other iguanas because they only grow from 5 inches up to 35 inches. The most outstanding feature of this iguana and the reason for its common name is the large spines on its tail. They are omnivores and basically feed on fruits and flowers as well as small insects.

Genus Dipsosaurus includes the desert iguanas of Southern America and Mexico. This iguana is full-bodied with an apex of elevated and expanded spines on its back. They have cream to white colored bellies and are spotted with white dots and striped colored tails. They can grow up to 15 inches long with a tail that is twice as long as its body.

Genus Sauromalus (Chuckwalla) is a robust herbaceous iguana commonly found in The United States and Mexico. They are strict vegetarians, eating only fruits, leaves and flowers. Chuckwallas have skins that hang loosely on their fat bodies; they love heat and basically do not move in the morning until the temperature reaches 100 degrees. They control extra heat by either changing color to reflect the sun's heat or hide in the shade. Chuckwallas are good as pets because they do not move much.

Genus Brachylophus or the Fijian Banded Iguana, is found in Fiji and Tonga.

Iguanas are considered endangered species and illegal possession of any type of iguana is punishable by law, so be sure that if you want an iguana as a pet, to have it registered first legally and consult veterinarians for advice and guidelines.
