Burmese pythons, one of the largest snake species in the world, could be the most destructive invasive animal in Florida Everglades history. They can swim, burrow and climb trees, and they eat almost anything, including prey much larger than themselves.

Pythons can go weeks without eating. Now researchers have isolated an appetite-suppressing metabolite in python blood that could spur a new weight-loss therapy.
