Description
Green Iguanas are large lizards, the largest among the Iguanidae family, and can grow up to 1,7 m in length. Its body is covered by smooth scales. Despite its name, the green Iguanas can actually have different body colors, from green, lavender, black, blue, yellow, orange to brick red; they vary geographically and sometimes by age. There is a row of spines on its back meant for protection. It has a long, thick and strong tail with dark stripes. Under its chin, it has a flap of folded skin called the dewlap, used to regulate its body temperature. It also has long, sharp claws to grasp on tree branches.
Behavior
Iguanas are arboreal and live in canopies or on top of trees near water. They are excellent climbers, utilizing sharp claws and long tails for balance in the trees.
When frightened by predators, they can try to dive into the water and swim away, using strong tail strokes to propel their bodies. If the predator is still hot on their trail, the iguanas may hiss and show its dewlap as an intimidation attempt. When cornered, iguanas can strike their opponent with their tail or use their claws for defense, they can also shed the tail to distract the predators as they flee.
Reproduction
They reproduce annually during the dry season to ensure hatchlings arrive when food is plentiful. Females lay clutches of 10–70+ leathery eggs in deep, sandy burrows, which incubate for 90–120 days without parental care.
Communication & Perception
They communicate primarily through complex, non-vocal, and visual body language, including head-bobbing, chin flap extensions, and stylized body movements. They use these signals to display territory, courtship, aggression, or submission, often in response to both other iguanas and their environment.

Fun Fact
Iguanas have a "third eye" or parietal eye, which is actually part of the pineal gland in reptiles. This third eye is marked by the presence of a discolored scale on the top of the iguana's head. It is used to help the iguana sense motion and changes in light, helping them avoid predators and enables them to tell night from day.
