Green Iguanas, archaic-looking tree-dwelling lizards from Central America, are kept by 10 million people as pets. In the wild, Iguanas live in the canopies of lowland rainforests in Central-and South America where they feed exclusively on foliage.

They are the only lizards known to breed "socially" in colonies, where several dozen females share nesting grounds with crocodiles and turtles . This unique behavior may provide insight to the way dinosaurs were living many million years ago. The images of this portfolio provide a broad and thorough insight in the natural history of this interesting species, including the unusual nesting behavior in colonies and interactions with other species.

Taking pictures for the Iguana story had been an adventure. Being prey for a variety of predators, those creatures are extremly shy and always ready for flight. They are often found on high branches along the shoreline, where they let themselves fall into the water in case of aproaching predators. There is a huge splash and they hide under water for a few minutes - befor returning to the surface.
