Banded iguanas spend almost all their lives in trees. Their toes have tiny gripping pads and curved claws that let them run along branches without slipping. They are so well camouflaged in green leaves that even a sharp-eyed observer standing a metre away can look straight at one and not notice it.
They eat mainly leaves, flowers and fruit - whatever is in season in the forest. In the dry season, when food is scarce, they can slow their bodies down and wait patiently. Being able to go without much food for a while is a very useful skill on a small island.
Male iguanas can change colour when they are excited - flashing brighter green or showing orange patches. This is how they communicate with each other across the treetops: a flash of colour can mean 'this is my tree' or 'hello, I am here'.
The Fijian crested iguana is a close cousin that lives on the island of Yadua Taba. It has three white crests on its back and is one of the rarest reptiles in the world. A community-run sanctuary on Yadua Taba protects the island so the crested iguanas can thrive.
