We will be heading back to Florida in about a month and I know that I have done Iguanas before but this guy has it all and he is running free and not in a cage or at the zoo. Iguanas are not indigenous to Florida, they were imported as pets. The fold of skin under his chin is called a dewlap and he can inflate it to attract females, intimidate rivals or scare off predators. The large round scale on his cheek is known as the subtympanic shield but it has no use other than to indicate that you are looking at a male. This guy is about 40 inches (100cm) long. He has a third eye (Parietal eye), visible as a pale scale, on the top of the head (above his eye) and used for sensing changes in light such as an aerial predator. Check out the claws and he has a nasty set of sharp teeth. Some info from Wikipedia. Zoom will work. Thanks for stopping by, taking a look and for all your previous favs and comments. They are very much appreciated. Dana
