What may be a yellow rat snake slithers through the grass on Kennedy Space Center. Yellow rat snakes are found throughout most of Florida and the Keys. They also live in a narrow strip along the Atlantic coast through Georgia, South Carolina and North Carolina. They are often found in warm southern swamps, and are also common in abandoned buildings and barns. Besides rats, yellow rat snakes will eat a wide variety of small mammals, birds, and eggs. They are considered the best tree climbing snake in Florida. The scales on their bellies are squared off, which aids them tremendously with climbing. They are strong constrictors, and kill their prey by suffocation. KSC shares a boundary with the Merritt Island Wildlife Nature Refuge. The refuge is a habitat for more than 310 species of birds, 25 mammals, 117 fishes and 65 amphibians and reptiles. In addition, the Refuge supports 19 endangered or threatened wildlife species on Federal or State lists, more than any other single refuge in the U.S. Photo credit: NASA/Dimitri Gerondidakis
