Green Iguana

Iguana iguana

The green iguana is a large arboreal lizard native to Central America, much of tropical South America, and several Caribbean islands. Despite the name, adults may be green, gray, blue-green, or orange, especially in breeding condition or in some regional forms. Iguana iguana has a long whip-like tail, strong claws, a row of dorsal spines, and a prominent dewlap used in display and thermoregulation. Hatchlings are often sold when they are small, but healthy adults can exceed five feet in total length and become powerful animals.

Keeping a green iguana is closer to maintaining a reptile room than a small terrarium. It needs tall climbing space, high-output ultraviolet lighting, and warm basking zones. Humidity must be managed, and the diet should be plant-based, built around calcium-rich leafy greens and vegetables. Poor lighting or diet can lead to bone and kidney problems. Mature males may become territorial, and even tame adults can injure people with tail strikes or bites, so handling and enclosure access must be planned. In places where released iguanas have become invasive, ownership rules may be strict and responsible rehoming is an important part of stewardship.
