If anyone ever looked at a lake, stream, or any body of water that makes up 70% of our earth and wondered what lives in there, this is the book with the answers. Every page explores the story of life underwater. Readers learn about unusual animals, like the crafty mudskipper that can live in water and on land so that it can escape from hungry saltwater crocodiles. The fact-filled text also explains the mutual dependency of plant and animal in these ecostystems; while seagrass provides food for pinfish, sea turtles, and manatees, the seagrass is maintained by several of species that live among it, such as sea horses and baby barracuda.

Common and not so common habitats are based on actual locations that readers can identify. Places such as a New England salt marsh or the rocky coast of British Columbia are illustrated with realistic detail. Maps and a glossary complete this learning experience.
