Blue iguanas on Grand Cayman island are no longer considered a critically endangered species. A decade ago, there were just 10 to 25 blue iguanas living in the wild and they were listed as critically endangered. It's a major victory for a breeding program that rears and releases blue iguanas on Grand Cayman, the only place in the world where the turquoise-colored reptiles live in the wild. Fred Burton is the director of the Blue Iguana Recovery Program. In a Friday, Oct. 19, 2012, statement, he said the program is confident that it can achieve its long-term goal of restoring 1,000 blue iguanas to Grand Cayman's shrublands.
