Did you know that sooty shearwaters travel more than one million miles and 6,000 days in their average life span of 32 years? Or that on coral reefs more than 100 cleaner species serve as doctors and dentists to other fish? These fun facts are featured in marine scientist Nancy Knowlton's new book "Citizens of the Sea." Written for a general audience, the book will also appeal to the scientific community and to educators looking to ignite students interest in marine life. In this podcast, Knowlton reads selections from her book.
