The blue iguana (Cyclura lewisi), endemic to the island of Grand Cayman, has one of the longest lifespans of any lizard, living up to 69 years. When the lizards are born, they are intricately patterned but barely blue, with only some parts of their bodies maintaining a pale blueish-gray color. As they mature, they become bluer in color. However, mature lizards have the ability to change color and usually make themselves gray in order to blend in with the rocks that are found throughout their habitat.
A blue iguana will only make itself blue when it comes in contact with other members of its species either to communicate with them or to establish its territory. Males of the species also tend to have a more pronounced blue color than females do.
