Iguana iguana (Common Green Iguana)


Wikipedia Abstract

The green iguana (Iguana iguana), also known as common iguana or American iguana, is a large, arboreal, mostly herbivorous species of lizard of the genus Iguana. It is native to Central, South America, and the Caribbean. Usually, this animal is simply called the iguana. The green iguana ranges over a large geographic area, from southern Brazil and Paraguay as far north as Mexico and the Caribbean Islands. They have been introduced from South America to Puerto Rico and are very common throughout the island, where they are colloquially known as "Gallina de palo" and considered an invasive species; in the United States feral populations also exist in South Florida (including the Florida Keys), Hawaii, the U.S. Virgin Islands and the Rio Grande Valley of Texas.

Invasive Species

The green iguana (Iguana iguana) is native to tropical parts of Latin America and grows to around 1.5m in length and 4 to 5kgs in weight. It is associated with warm coastal regions, low elevations and waterways, especially where trees extend over water. It inhabits mangrove forests and saltwater habitats, but requires access to freshwater. Popular as pets throughout America and Europe, green iguana owners often do not realise the lizard's space requirements and release them into urban areas when they grow too big. I. iguana is reported as an exotic pest in Puerto Rico. It also occurs in high concentrations in urban areas of southern Florida. It consumes and defecates the fruits of invasive plants, thereby acting as a potential dispersal agent. It has been cited as the source of a number of laboratory-confirmed cases of human salmonellosis.
