Scientists believe American alligators have been around for nearly 150 million years, but they came close to going extinct. American Alligator explores the alligator's key role in its habitat, how hunting and habitat changes almost led to its extinction, and how efforts such as egg collection and controlled hunting help to preserve the species. Easy-to-read text, vivid images, and helpful back matter give readers a clear look at this subject. Features include a table of contents, infographics, a glossary, additional resources, and an index.
