Iguanas are the cold blooded animals which are the most intelligent of all reptiles. They are a genus of lizard native to tropical regions of the Caribbean, Central and South America. They are costly not in terms of their tag prices but they are the most expensive animal to care for. However, of all the pets, they are the most economical reptile to keep. Some of their species are spiny-tailed iguanas, desert iguanas, and green iguanas. The green iguana is the most preferable species among the kids. Iguanas can live up to 20 years and grow in a big size within this length of time.

Most iguanas have a row of spines running along their back to their tail, and a third parietal eye (looks like a pale scale) on top of their heads. There are also small spike-like scales called tuberculate scales behind their necks. A large round scale called subtympanic shield is located on their cheek. Generally, iguanas have excellent vision as they are able to see shadows, colors and even detect any movements at long distances. Not only they use their eyes to crawl through the crowded and thick forests, but also they are used for searching food. The visual signals help them to communicate with other companions of the same species. Their ear’s drum called tympanum is found right above the subtympanic shield and behind the eye. They use this very thin and delicate part for hearing.
