This book in the Little Explorers series takes young readers from the seashore to the ocean floor, finding fascinating plants and animals and solving ocean mysteries along the way.

Let's meet some of the amazing sea life that calls the ocean home. What creatures live where there is no sunlight? How do tides work? Is coral a plant or an animal? Search for the answers to these questions and more in the pages of this book.

With engaging text and realistic illustrations, young readers will adventure through the fascinating underwater world of our planet's oceans. Learn why some sea creatures glow, and how sharks can be as small as a pencil or as long as a bowling lane. From the helpful kelp forests of the shallow sunlight zone to the cold depths of the abyssal zone, interesting plants and animals abound - and many mysteries too.
