Green Iguana
Rainforests, mangroves, and along riverbanks
The Green Iguana, iguana iguana, is a large, arboreal lizard native to Central and South America. Recognizable by its vibrant green scales, this reptile can grow up to 2 meters in length, including its tail, which it uses as a defense mechanism against predators. The Green Iguana has a row of spines along its back to the tail, aiding in protection and thermoregulation, and a dewlap under its chin, which can be expanded to appear more imposing or to help with body temperature regulation. Males are generally larger than females and have more pronounced dewlaps.
| Population: | Listed as Least Concern, but faces threats from habitat loss and the pet trade |
| Generation Length: | 4-8 years |
| Average Weight: | 4-5 kg |
| Average Length: | 1.5-2 meters, including the tail |
| Lifespan: | 10-20 years in the wild |
| Diet: | Herbivorous, with a preference for tender leaves, shoots, and fruits |
| Conservation Status: | Least Concern (LC) |
Green Iguanas are primarily found in rainforest canopies near water sources like rivers or lakes. They are adept swimmers and will plunge into the water to escape from danger. These reptiles are diurnal, spending most of their daylight hours sunbathing to regulate their body temperature, and are known for their excellent climbing abilities, which allow them to navigate through their arboreal habitats.
The diet of the Green Iguana is herbivorous, consisting mainly of leaves, flowers, and fruits. This feeding behavior is crucial for the ecosystem as it helps in seed dispersal and maintaining the balance of vegetation in their habitats. Young iguanas may consume insects or other small animals, but as they grow, their diet shifts entirely to plants.
Reproduction in Green Iguanas involves elaborate courtship displays by males to attract females. They are oviparous, with females laying clutches of 20 to 70 eggs once a year in burrows or other protected ground areas. The eggs are left to incubate for about 90 days, and the hatchlings are entirely independent upon emergence, receiving no parental care.
The population of the Green Iguana is considered stable in the wild, though it faces threats from habitat destruction, hunting for the pet trade, and as a food source. In some regions, they are considered invasive species, impacting local ecosystems. Conservation efforts focus on habitat preservation and regulating trade to ensure their survival. The Green Iguana's striking appearance and behavior have made it a popular subject in research and a favored pet in the exotic animal trade, though they require careful management to thrive in captivity.

Fun Fact
Green iguanas can fall up to 50 feet without getting hurt. They are excellent climbers and swimmers.
These reptiles have a unique ability called autotomy, allowing them to shed their tails to escape predators. They can regrow the tail over time. Green iguanas are also herbivores and primarily eat leaves, flowers, and fruit. They rely on the sun for thermoregulation, often basking on tree branches.
