Species overview
About the Helmeted Iguana
The helmeted iguana has a conspicuous raised casque behind its head, a long tail and a strongly camouflaged body. Brown, olive and pale patches merge with tree bark and shadow. Its stillness can make it harder to detect than its unusual shape suggests.
It is a forest lizard, not a chameleon. Observe its grip and upright posture without making it move. An animal remaining still has not given permission to be handled. Let the forest’s quiet expert keep its chosen place on the trunk.
