🐍 Introduction

The green iguana is a large, plant-eating lizard found in warm tropical regions of Central and South America, as well as parts of the Caribbean. Known for its bright green body, long tail, and excellent climbing skills, it is one of the most recognizable reptiles in the world.Green iguanas spend most of their time in trees, where they bask in the sunlight and feed on leaves, flowers, and fruits. They are skilled swimmers and can dive into water to escape predators.

🦎 Appearance

Green iguanas can grow between 5 and 7 feet (1.5-2 meters) long, with more than half of their length made up of their tail. Their skin is usually bright green but can also appear blue, brown, or orange, depending on their age, mood, and environment.They have a row of spines along their back, a large dewlap (flap of skin under the chin) for communication, and strong legs with sharp claws for climbing trees.

🌍 Habitat

These lizards live in tropical rainforests, coastal mangroves, and riversides. They are found from southern Mexico through Central America, down to Brazil and Paraguay, and on some Caribbean islands.They prefer areas with plenty of vegetation and access to water, often basking high in trees overhanging rivers.

🍽 Diet

Green iguanas are herbivores, eating mostly leaves, flowers, and fruits. Young iguanas sometimes eat insects, but adults rely almost entirely on plants. They use their sharp teeth to tear vegetation and need warmth from the sun to help digest their meals.

🔄 Life Cycle

Female iguanas lay 20-70 eggs in sandy burrows. The eggs hatch after about 90 days, and the hatchlings are independent from birth. Young iguanas live in small groups for protection but become more solitary as they grow.In the wild, they usually live 10-15 years, but in captivity they can live up to 20 years with proper care.

🐾 Behavior and Social Structure

Green iguanas are mostly solitary but may gather in groups where food is plentiful. They are diurnal (active during the day) and spend hours basking in the sun to regulate their body temperature.Males are territorial during breeding season, using head bobs, dewlap displays, and tail whips to warn rivals.

🛡 Conservation Status

• IUCN Red List: Least Concern (LC)

• Main Threats: Habitat loss, hunting for food, and the pet trade.

• Conservation Efforts: Protected in some regions; breeding programs and awareness campaigns help reduce wild capture for the pet industry.
