Cayman blue iguana (Cyclura lewisi) is one of the critically endangered species in the world. The wild population of blue iguanas is expected to be extinct within 10 years. There is however new hope on the horizon. Three eggs laid by a Grand Cayman blue iguana that had been released into a nature reserve on the Caribbean island have successfully hatched. Durrell Wildlife Conservation Trust. UK Is heading this successful captive breeding and release programme
