Alligators have clashed with non native pythons before in Everglades National Park. A 13 ft long python tried to swallow a 6 ft alligator whole and then exploded. Scientists have documented four similar encounters in the last three years. The encroachment of Burmese pythons into the Everglades could threaten an $8 billion restoration project and endanger smaller species, said Frank Mazzotti, a University of Florida wildlife professor. The gators have had to share their territory with a python population that has swelled over the past 20 years after owners dropped off pythons they no longer wanted in the Everglades. The Asian snakes have thrived in the wet, hot climate. “Encounters like that are almost never seen in the wild – and we here are, it's happened for the fourth time,” Mazzotti said. In the other cases, the alligator won or the battle was an apparent draw.
