An alligator looks warily at the photographer who's spotted the familiar head in a drainage canal on NASA's Kennedy Space Center in Florida. A protected species, alligators can be spotted in the drainage canals and other waters surrounding KSC. The center shares a boundary with the Merritt Island Wildlife Nature Refuge, which is a habitat for more than 310 species of birds, 25 mammals, 117 fishes and 65 amphibians and reptiles.
