An eastern diamondback rattlesnake slithers through the grass near the NASA News Center at NASA's Kennedy Space Center. The diamondback is Florida's largest venomous snake and may exceed six feet in length. It lives throughout Florida in a variety of dry habitats, such as pinelands, scrub and golf courses. Kennedy 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.
