Iguanas eat valuable landscape plants, shrubs and trees as well as orchids and many other flowers. Iguanas do not like citrus, but they will eat fruit such as berries, figs, mangoes, tomatoes & bananas.
Iguanas are certainly one of the most popular lizards to have ever been kept as a pet. Iguanas have strict feeding and housing requirements, can grow quite large, live a long time, and can be quite strong. They can be difficult to tame and become aggressive if not regularly handled. They are a big commitment and require a high level of care. This is not to say that iguanas cannot make good pets but they need the proper care right from the start and owners need to have the right expectations. Many new reptile owners do not realize how large their lizard of choice gets, how long they live, what kind of food is needed to keep them healthy, and all of the costs associated with these needs. As more and more people realized that iguanas are a large and long-term commitment, they have decreased in popularity.
For a land animal, the iguana is a talented swimmer. It is at home on land, in trees and in the water. It uses its swimming abilities to protect itself from prey and find food. One species of iguana is actually considered a marine animal.
Iguana meat is legal in the United States of America and several other countries, however importation is restricted due to CITES conventions.

There has been a marked preference for the green iguana over the black iguana in the region, though both are eaten.

Proper preparation of the iguana requires boiling it in water for twenty to thirty minutes before roasting or stewing it. Common recipes for the iguana include stews (guisado), pozole, birria, roasted in tacos and flautas, roasted and finished with mole, and even sautéed with almonds.

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.
Homeowners do not need a permit to kill iguanas on their own property, and the FWC encourages homeowners to humanely kill green iguanas on their own property whenever possible. Iguanas can also be killed year-round and without a permit on 22 public lands in south Florida.”
