Burmese pythons, native to Southeast Asia, that either escaped or were released by their owners started breeding in the wild and began eating every animal in their path. A group of scientists at the Conservancy of Southwest Florida are tracking the snakes to find ways to stop their proliferation, which could change the ecosystem of the Everglades. Messner does a good job of describing the sometimes-messy work of scientists who work in the field and in the lab. She delves a bit into invasive species and responsible pet ownership. Captioned photographs, maps, and diagrams add information. Videos of some of the episodes described are available via QR codes scattered throughout the book. Overall, a well constructed book that might inspire budding scientists and others fascinated by 100-pound snakes. Recommended for middle school students.
