Every year in Namibia, about two thousand zebras suddenly disappear from their grazing area along the Chobe River. Months later, the herd returns. Where do they go? And why? Thanks to satellite-tracking collars, scientists were able to solve the mystery, but several questions remain. Award-winning science author Sandra Markle reveals the process scientists used to study the zebras, and she also delves into the science of migration, exploring how animals know where to go, how to get there, and when to leave.
In the history of life on this planet, 99.9 percent of all species have gone extinct. But a few have survived almost unchanged. Author Rebecca E.

Readers will also discover a a spectacular timeline of the history of animal life on Earth. Dive into the stories of these incredible animals and find out how they help scientists piece together evolutionary history.
Burmese pythons are native to Southeast Asia, so when one showed up dead along the side of a Florida highway in 1979, scientists wondered where it came from. No one knew the snakes had launched a full-scale invasion. Pet pythons that escaped or were released by their owners started breeding in the wild, and these enormous predators began eating every animal in their path. Today a group of scientists at the Conservancy of Southwest Florida is tracking Burmese pythons to find ways to stop their spread. Page Plus links lead to video clips and photos of the scientists working in the field. Delve into the science of pythons and their role as invasive predators.
