America's Longest Snake Slithers for Cover

The eastern indigo is the longest native snake species in the United States. Typically ranging between five and seven feet long, this nonvenomous serpent has iridescent scales that appear blackish-purple in sunlight. This snake calls woody areas near bodies of water in the southeastern United States home. But habitat loss means that you probably won't spot these guys in the wild.
