The green iguana (Iguana iguana) is a large lizard native to Central and South America and the Caribbean islands. Despite being primarily herbivores, their populations are threatened by habitat destruction, the pet trade, and being consumed as food in some areas.
The Green Iguana: A Comprehensive Overview
Physical Characteristics and Habitat
The green iguana (Iguana iguana) is a large, recognizable lizard native to Central and South America, as well as the Caribbean islands. It has adapted to thrive in various environments, including tropical rainforests, mangroves, and dry forests.
-
Coloration: They have a vibrant green color that helps them blend into leafy environments, although some individuals may display shades of blue, orange, or yellow depending on their age and region.
-
*Physical Features:
-
A prominent dewlap under the chin
-
Spines along their back and tail
-
Strong limbs with long claws and specialized toes for climbing trees
-
Excellent long-distance vision and sharp color vision
-
A third eye (parietal eye) on top of their head to detect predators
Social Habits and Behavior
Green iguanas exhibit both social and solitary behavior, depending on their age and life stage.
- Adult Green Iguanas: Fiercely independent, only interacting during the mating season when basking or feeding in the same area.
Diet and Adaptation
Green iguanas are primarily herbivores, consuming a strictly plant-based diet consisting mainly of leaves, flowers, and fruit. This makes them essential for seed dispersal in their habitats.
-
Juvenile Iguanas: May occasionally eat insects.
-
Adult Green Iguanas: Stick to a plant-based diet, indicating their adaptation to urban environments in places like Florida and Hawaii.
Conservation Status
While green iguanas are not yet vulnerable, habitat destruction and the pet trade threaten some local populations. Additionally, eating green iguanas is part of traditional diets in some areas, further impacting their numbers.
Wildlife conservation efforts aim to balance the preservation of green iguana habitats while addressing their negative impacts in non-native regions.
Length and Coloration
Adult iguanas have a prominent dewlap under their chin and spines along their back and tail. They have strong limbs, long claws and specialized toes designed for climbing trees. Most green iguanas also have excellent long-distance vision and sharp color vision. And they have a third eye (called the parietal eye) on top of their head that helps them detect predators from above.
Diet
Habitat Adaptation
Green iguana populations expanded beyond their native range, and in places like Florida and Hawaii, these wild iguanas have adapted to urban environments. There, you may find a green iguana basking on a sidewalk or lounging near canals.

Conservation Efforts
Distribution and Native Range
The species is native to the tropical regions of Central and South America and some of the Caribbean islands. They also exist in Florida and Hawaii, though they are seen as invasive species in those states because they eat their native plants.
