Blue Iguana (1 of 2) (image) Wildlife Conservation Society Caption This is an adult Grand Cayman blue iguana on its namesake island. Decimated by a combination of habitat destruction, car-related mortality, and predation by introduced cats and dogs, the reptile numbered between 10-25 individuals by 2002. A recovery program -- assisted by health experts from the Bronx Zoo -- has brought the number of free-ranging iguanas within Grand Cayman's protected areas to more than 500 animals.
