The green iguana (or Iguana iguana) is a large species of lizard that lives throughout Central America, Northern South America and the Caribbean. It has a long tail with a serrated crest that goes from its head to the base of its spine, as well as muscular legs with long toes and claws. They may also have striations on their tail and body. Although named ‘green’ iguanas, they occur in many colours – commonly green, blue, brown and orange – and these different colour morphs often depend on their location of origin. Whatever the colour, the green iguana can reach 2m in length including the tail, and males are larger than females, weighing an average of 4kg compared to 2kg.

Animal Facts
Green iguanas are agile climbers and can fall up to 18m without sustaining an injury.
Green iguanas are excellent swimmers and use their strong tails to propel themselves through the water.
Green iguanas have a flap of skin hanging from their chin called a 'dewlap'. Movement of the dewlap is a method of communication between iguanas.
Green iguana hatchlings have a special tooth called a 'caruncle' that is used for breaking through the shell of their egg. It falls off shortly after hatching.
Green iguanas have a rudimentary third eye on the top of their head known as a 'pineal eye', which is sensitive to changes in light levels and movement.
