Pythons have invaded the Everglades, where they flourish in warm, wet habitat that has an abundant buffet of native species to feast on.
The giant snakes were imported to North America as pets, but released or escaped into Florida's wetlands they are proliferating, challenging alligators for the top of the food chain, and potentially positioning themselves to invade much more of the United States.

He is worried about the impact on indigenous species--and what could happen if pet owners release other big reptiles into the watery wilderness. (Source: National Geographic)
