Iguana Senses
 Iguanas have excellent vision and can see long distances, shapes, shadows, color and movement. An iguana uses its eyes to navigate through trees and forests, as well as for finding food. They also use their eyes to communicate with members of the same species. An iguana's ear is called a tympanum. It is the iguana's ear drum and is found right above the subtympanic shield and behind the eye. This is a very thin, delicate part of the iguana, and is very important to its hearing.
