Burmese pythons are a popular kind of pet snake in the United States. However, they're meant to live in India and parts of China—not Florida. These huge snakes can harm people and generally disrupt the food chain of southern Florida enough for them to be called an invasive species. This book introduces readers to the concept of "native" and "invasive" animals through the facts surrounding the spread of Burmese pythons. The main content covers how the snakes came to be in southern Florida, their harm to the environment, and modern ways conservation groups are trying to stop their spread.
