"Blue Iguana," Wikipedia, the free encyclopedia. The blue iguana, also known as the Grand Cayman iguana, Grand Cayman blue iguana or Cayman Island blue iguana, is an endangered species of lizard endemic to the island of Grand Cayman. Previously listed as a subspecies of the Cuban iguana (Cyclura nubila), it was reclassified as a separate species in 2004 because of genetic differences discovered four years earlier. The blue iguana is one of the longest-living species of lizard (possibly up to 69 years). The record is 67 years. The blue iguana is the largest native land animal on Grand Cayman with a total nose-to-tail length of 5 ft (1.5 m) and weighing as much as 30 lb (14 kg). It may be the heaviest species of iguana and most massive lizard in the Western Hemisphere. Its body length is 2030 inches (5176 cm) with a tail equal in length. The blue iguana's toes are articulated to be efficient in digging and climbing trees. Although not known to be arboreal, the blue iguana has been observed climbing trees 15 feet (4.6 m) and higher. The male is larger than the female by one third of his body size.
