(01/08/1999) -- An alligator lurks in the murky, mossy waters of the Merritt Island National Wildlife Refuge at Kennedy Space Center. Its tail surfaces behind him, looking like a log in the water. The wildlife refuge harbors nearly 5,000 American alligators, some of which can be seen in the canals and ponds around KSC. The refuge is also habitat for more than 310 species of birds, 25 mammals, 117 fishes and 65 amphibians and reptiles. The open water provides wintering areas for 23 species of migratory waterfowl and a year-round home for great blue herons, great egrets, wood storks, cormorants, brown pelicans and other species of marsh and shore birds
