“Iguanas” have a distinctive and memorable appearance, namely the “wattle” which is a large round leather patch under the chin. From the neck to the middle of the back, there is a continuous row of spines extending all the way to the tail. If you look at the “cheeks” there are new circular scales called the subtympanic shield, and there is an ear canal behind each eye. Come to Aquaria Phuket and take a look.
