Endangered

At very high risk of extinction in the wild in the near future.

Spotted something wrong?

The Grand Cayman blue iguana is a large lizard endemic to the island of Grand Cayman, which takes on an intense turquoise blue when basking or during the breeding season. In 2002 there were between ten and twenty-five individuals left in the wild and the species was given up as doomed. A captive breeding and reintroduction programme has taken the population past a thousand.

Fun facts

  • GeneralIt was once down to a dozen animals; today there are over a thousand, thanks to captive breeding.
  • In 2002 there were between ten and twenty-five animals left in the wild: it was one of the most threatened species on the planet, and today it numbers more than a thousand thanks to a breeding and reintroduction programme cited as a benchmark success.
  • Its blue deepens with heat and in the breeding season: a cold or stressed animal is brownish grey, and the turquoise that gives it its name appears only when it is active in the sun.
  • It can live more than sixty years, and some of the founder animals of the recovery programme are still alive and breeding two decades on.
