Explanation:

Burmese Pythons are non - native to Florida. They have established a large population in the Florida Everglades. They prey on native wildlife such as mammals (e.g., raccoons, opossums), birds, and reptiles. Their large size and high reproductive rate have disrupted the local ecosystem balance. Timber Rattlesnakes are native to parts of the United States (including some areas in the eastern US but not an invasive species causing major problems in the context of Florida's invasive species issue as described here).
