The green iguana is also known as the Common iguana or American iguana. Green iguanas are native to areas such as South and Central America, as well as in the Caribbean and islands in the West Indies. They also roam the landscapes of countries like Brazil, Paraguay, and Mexico, where they’re considered to be an endangered species. Human intervention has also been responsible for these reptiles being introduced to locations as diverse as the U.S., Puerto Rico, and the Virgin Islands. In North America, green iguanas are considered to be an invasive species in such states as Florida, Hawaii, and Texas. Green iguanas are also popular as pets, and kept in captivity as such in various parts of the world.
Green iguanas can reach a size of almost five feet in length, and achieve weights of almost 20 pounds. Although these greenish, gray-toned animals have a stout looking body, they’re actually fast-moving creatures who have the capacity to skillfully evade natural predators before taking cover beneath thick vegetation. Despite being herbivores, green iguanas have sharp teeth, powerful jaws, and strong tails. It’s interesting to note that the tail section of the green iguana makes up about half of its overall length. The reptile also makes optimum use of its tail by engaging it as a means of self-defense. Green iguanas have the ability to powerfully move this appendage in a threatening whip-like fashion, meant to ward off potential dangers. The green iguana’s tail also has the capacity to detach itself, and can then be regrown without incurring any lasting damage.
As herbivores, green iguanas subsist on a diet rich in plant material. Food sources for the reptile include such vegetation as flowers, leaves, and various types of fruit. Occasionally, the green iguana may also consume insects to supplement its nutritional regimen, with this being especially true for young iguanas with increased need for minerals, vitamins, and quality proteins to grow. In the wild, green iguanas search for food during the day, and are known to regularly return to the same feeding areas time and time again. These animals get the majority of their water intake by relying on rainwater, and the condensation found pooled up on an array of plants. When kept in captivity, the green iguana is typically fed a nutrient-rich diet composed of salad greens, lettuce, sweet potatoes, carrots, and kale.

Green iguanas are a social species who spend most of their time gathered in groups. Males of the species are usually more aggressive and territorial than their female counterparts. These reptiles are skilled swimmers who use their tails in order to navigate through the water. These creatures can remain beneath the water's surface for up to half an hour at a time. The green iguana’s nostrils have the ability to expel a substance rich in salt, a mechanism used to control salt levels in its body. When confronted with danger, Green iguanas adopt an aggressive posture which includes expanding theirs dewlaps (flaps of skin under their necks), puffing up their entire bodies, and making hissing noises. In captivity, green iguanas can reach 20 years of age.Iguanas on a seawall in Hallandale Beach, Florida.

The Florida Fish and Wildlife Conservation Commission said people should exterminate the lizards on their properties as well as on 22 areas of public land. It did not say how civilians should try to kill them.
“Homeowners do not need a permit to kill iguanas on their own property, and the FWC encourages homeowners to kill green iguanas on their own property whenever possible, ” the agency said.

Iguanas are not dangerous or aggressive to humans but they can dig lengthy tunnels, damaging pavements and building foundations. They can sometimes carry salmonella bacteria.
Males can grow to at least 5ft (1.5 metres) long and weigh 9kg (20lb), and females can lay nearly 80 eggs a year.
“Some green iguanas cause damage to infrastructure by digging burrows that erode and collapse sidewalks, foundations, seawalls, berms and canal banks, ” the wildlife commission said. “Green iguanas may also leave droppings on docks, moored boats, seawalls, porches, decks, pool platforms and inside swimming pools.”

Iguanas are native to Central America, tropical parts of South America and some Caribbean islands. They were brought to Florida as pets or inadvertently on ships and have begun to flourish in the state, where the warm climate is perfect for them.
Some have been reported in northern parts of Florida, but their spread is more limited there as they do poorly in colder weather.
Another invasive species, the Burmese python, is wreaking havoc in the Everglades as they eat almost anything and have no natural predators in the US, except for the occasional alligator.

Iguanas are allowed to be kept as pets in Florida but are not protected by any law except those prohibiting cruelty to animals. The commission takes in pet iguanas whose owners can no longer care for them under an exotic pet amnesty programme that lines up adoptions of the animals.Unlike the infamous but elusive Burmese python, iguanas freely mingle with people — and often act like they own the place. One jaunty male was videoed recently strolling Miami Beach’s Lincoln Road while others pose unperturbed for pictures along the crowded promenade. They sun on docks and decks across South Florida, poop in pools and graze on gardens. They’ve undermined the kitchen at a golf course restaurant in Cooper City and canal banks along Miami’s Little River.
They’ve now been spotted in the wild across much of the state, everywhere from Gainesville down to Key West, where they have a habit of shorting out power lines.
Florida wildlife managers know they’re a problem. Citizen complaints about the invasive reptiles had become so numerous that they made a tentative stab at doing something about it early this year, giving the green light for residents to “humanely kill green iguanas on their own property whenever possible.”
Iguana Bite Can Lead To Rare Bacterial Infection, New Study Says
But the state quickly softened that approach after backlash from animal rights groups, to the point where the agency now refuses to even explain how to humanely dispatch one.
Still, there is no getting around the fact that South Florida has an exploding population of giant exotic lizards and no real plan to do anything about it. The sparse research on their numbers, how fast the population is growing or how much damage they are doing is narrowly focused or outdated.
In 2007, a group of scientists including researchers from the University of Florida and state agencies sought to document the geographic distribution, reproduction and potential ecological impacts of the green iguana. They tallied up 3, 169 documented lizard sightings from May 1992 through December 2006 from just south of Lake Okeechobee to Key West. While nobody’s counting them today, it’s fair to guess that there are easily that many on Key Biscayne alone.
Iguana Lifespan: How Long Do Iguanas Live?
As for impacts, based just on anecdotes, it’s a lot. One agency, the South Florida Water Management District, has dealt with so many issues from big burrowing lizards that it’s working on what appears to be the state’s first formal assessment of iguana damage — if only to drainage canals crisscrossing much of the region.
The only thing wildlife managers and scientists can say for sure is that the iguana population has come back with a vengeance from a freeze that killed off many of them a decade ago. Iguanas are vulnerable to cold — their body temperatures depend on conditions outside — and enter a lethargic state when temperatures dip below 50 degrees, sometimes dropping from trees in chilled stupor.
They eventually die if a serious cold snap sticks around for more than three days. But that hardly ever happens in South Florida and with climate change raising average temperatures, extended cold snaps may occur even less frequently.
The Green Iguana
“They are in paradise, ” said Frank Mazzotti, a University of Florida wildlife biologist and reptile expert. “Their populations are growing and their range is also expanding.”
Florida’s relationship with iguanas is complicated and often contradictory. People kind of like them, but don’t really want them on their properties. Even many people who want them removed from their homes don’t like the thought of killing them like rats or roaches.
“A lot of people have mixed feelings about iguanas because they are cool animals: they look exotic with their beautiful colors and aren’t dangerous, ” said Brian Wood, a trapper who’s been catching iguanas in South Florida for more than 10 years. “People have a hard time treating them as the pests they really are.”

They’re not aggressive and don’t hurt pets, though their droppings can be a source of salmonella bacteria, which causes food poisoning. And unlike the Burmese python, another invader that poses a well-documented threat to the Everglades and has wiped out entire populations of small mammals in the threatened ecosystem, the mostly vegetarian iguana is only a problem to a select number of native
