A large species of lizard within the genus Iguana possesses a dewlap, a row of spines running down their back to their tail, and a third eye on their head. This eye is known as the Parietal eye, which looks just like a pale scale on the top of their head.
Behind their neck are small scales which resemble spikes, known as tuberculate scales. They also have a large round scale on their cheek known as a subtympanic shield.
An iguana’s ear is known as the tympanum. It is the iguana’s ear drum, and is located right above the subtympanic shield and behind the eye. This is a very thin and delicate part of the iguana, and crucial to their hearing.
Location Central and South America and the Caribbean
