A rare albino alligator is shown in its habitat at the Cypress Swamps at the California Academy of Sciences building in Golden Gate Park in San Francisco, California September 18, 2008. The facility's new design unifies the Academy's original set of 12 buildings, features a natural history museum, aquarium, planetarium and research facility all under a "living roof", and is one of ten pilot "green building" projects of the San Francisco Department of the Environment.
