blue iguana

The blue iguana, also known commonly as the Grand Cayman ground iguana, the Grand Cayman blue iguana, and the Cayman Island rock iguana, is an endangered species of lizard in the family Iguanidae. The species is endemic to the island of Grand Cayman. It was previously considered to be a subspecies of the Cuban iguana, Cyclura nubila, but in a 2004 article Frederic J. Burton reclassified it as a separate species because, according to him, the genetic differences discovered four years earlier between the different C. nubila populations warranted this interpretation. The blue iguana is one of the longest-living species of lizard.
