Snakes !!!

MIAMI (Reuters) - Burmese pythons and other giant snakes imported as pets could endanger some of America's most important parks and wilderness areas if they are allowed to multiply, according to a report released on Tuesday.

Wildlife experts say the Burmese python is distributed across thousands of square miles (kilometers) in south Florida. There could be tens of thousands in the Everglades, a wildlife refuge that is home to the Florida panther and other endangered species.

The Burmese python and four other non-native snakes -- boa constrictors, yellow anacondas, northern and southern African pythons -- are considered "high-risk" threats to the health of U.S. ecosystems because they eat native birds and animals, the U.S. Geological Survey report said.
