Renowned rattlesnake expert Bruce Means travels throughout the southeastern United States to determine how America's largest venomous snake --the Eastern Diamondback Rattlesnake-- has been able to survive in the face of human encroachment, while other large-bodied snakes --like the Indigo Snake, the Pine Snake, and the Kingsnake-- are in severe decline. Bruce believes that the Eastern Diamondback may respond to human encroachment by living in greater densities --more snakes per acre-- than other species of large snakes. Bruce's preliminary data indicates that he's correct: Eastern Diamondbacks are indeed capable of not only surviving --but thriving-- within small habitats. Bruce ventures deep into the swamps of Florida's Wakulla Springs State Park --an area not normally thought of as rattlesnake habitat-- and find that the Eastern Diamondback has adapted to live in this watery new terrain.
