Blue Iguana

Endemic to Grand Cayman, this striking blue iguana is one of the most endangered lizards on Earth. Indeed, at the time of its original description in 1940 the Cayman Island blue iguana was already considered to be on the brink of extinction. Blue iguanas normally possess a blue-grey complexion when resting but are better known for the stunning azure blue they turn during the breeding season or when excited. The Cayman Island blue iguana is a relatively large iguana, with males larger than females. Previously listed as the subspecies Cyclura nubila lewisi, this iguana has recently been recognized as a full species, Cyclura lewisi.
