Under water, the Ghost's colorless skin occasionally appears orange when it reflects his surroundings. He has 13 siblings, all of them discovered in 1987 just as they were hatching at an alligator farm in Golden Meadow, La. An alligator's sex is determined by the temperature of the nest, with higher temperatures producing males and lower temperatures producing females. Although alligators can live 60 to 70 years, ones like the Ghost are thought to be less robust than others. Five other reptiles are part of the exhibit, which runs Saturday through Sept. 3.
Visitors still can touch animals in the petting zoo.
