This volume of the six book "Discover Hawaii's" nature series introduces young readers to some of the unusual animals that live in Hawaii's freshwater streams and wetlands. To set the stage, we learn how fresh water is recycled in nature, and how plants play a vital role in this-how vegetation on land helps bring fresh water to the island, helps hold it in the ground, and helps Hawaii's offshore coral reefs to survive. Young readers learn about the strange lives of certain Hawaiian fish, shrimps and snails that spend their entire adult lives in fresh water, but produce young that must live in salt water. How could this be? The book explains. Some of these unusual fish can even climb straight up waterfalls! Young nature explorers can use Discover Hawaii's Freshwater Wildlife as an illustrated guide and tool to take with them as they visit different wetland areas. Like other books in this series, Discover Hawaii's Freshwater Wildlife has a conservation message. It describes threats that are undermining Hawaii's freshwater wildlife, and concludes with suggestions of simple things we can do to help. Full color illustrations on every page. Text and illustrations are equally balanced throughout the book. Includes Table of Contents, Glossary and Index.
