Green Iguanas, scientifically known as Iguana iguana, are one of the most recognizable and popular reptiles in the pet trade, native to the tropical rainforests of Central and South America. These large, arboreal lizards can grow up to 6 feet in length, with their long tails accounting for over half their body length. Green Iguanas are primarily herbivorous, feeding on a diet of leaves, flowers, and fruit. In the wild, they play a crucial role in their ecosystems by aiding in seed dispersal through their consumption of various plant materials. Their bright green coloration, which can sometimes include shades of blue, orange, or red, provides effective camouflage among the lush foliage of their habitat.

One of the most fascinating aspects of Green Iguanas is their remarkable adaptability and complex social behaviors. These reptiles are excellent climbers, using their sharp claws and strong limbs to navigate through the treetops. They also possess a dewlap, a flap of skin under their chin, which they use for communication and thermoregulation. Males display their dewlap and perform head bobs to establish territory or attract females. Additionally, Green Iguanas have a parietal eye, also known as a "third eye," on the top of their heads, which can detect changes in light and shadow, helping them evade predators. Despite their relatively calm demeanor in captivity, Green Iguanas can be quite territorial and aggressive during the breeding season. Their ability to adapt to various environments, combined with their striking appearance and behaviors, makes them both fascinating pets and important subjects of study in the wild.
