When Burmese pythons began slithering across Everglades levees in increasingly alarming numbers, state water managers petitioned the federal government to crack down on the pet trade’s sale of the giant snakes.

In the five years since, a string of studies, congressional hearings, articles and nature shows — not to mention bad sci-fi movies — have painted the python as a monstrous ecological menace that threatened to spread to other states.

But the proposal to ban the import and interstate sale of Burmese pythons and eight other large exotic snakes has stalled, swallowed up in White House bureaucracy for nearly a year. A bipartisan group of lawmakers has written letters urging the Obama administration to approve the snake ban — among them, Democratic Sen. Bill Nelson last month, Tampa-area Republican Rep. Bill Young this month and Miami Republican Rep. Ileana Ros-Lehtinen last week.
