Iguana

Iguana is a lizard that lives in the tropics of Central and South America, as well as the Caribbean. The Green Iguana and the Lesser Antillean Iguana are the only two species of Iguana.

Both lizard species have a dewlap and a band of spines running down their backs to their tails, as well as the third eye on their heads. The parietal eye, which resembles a pale scale on the top of their head, is the name given to this eye. Tuberculate scales are tiny scales that look like spikes on the back of their neck. A subtympanic shield, a broad round scale on their cheek, is also present.

Long-distance vision, forms, shadows, color, and movement are all visible to iguanas. Iguanas use their eyes to move through trees and woods and to find food. They often interact with other members of their species using their eyes. The ear of an iguana is known as a tympanum. It is the eardrum of the iguana, and it is located directly above the subtympanic shield and behind the eye. This is a very small, sensitive part of the iguana’s body that is crucial to its hearing.

Iguanas have evolved a herbivorous lifestyle, relying solely on plants and foliage for sustenance. Herbivorous lizards must have a higher bite force than their size in order to collect, process, and digest plant matter. According to one report, the iguana’s skull has been modified, resulting in a powerful bite force and effective vegetation processing.

Herbivorous lizards (such as the iguana) have higher and broader skulls, shorter snouts, and bigger bodies than carnivorous and omnivorous reptiles in order to do this biomechanically.

Acrodontal placement refers to the placement of the Green Iguana’s teeth on the surface of the jawbone. Furthermore, the iguana’s teeth are acrodontal, meaning that they rest on top of the jaw bone’s surface and project upwards. The teeth are tiny and serrated, allowing them to grasp and shear food.
