We know more about Mars than we do about the oceans.

Yet every child is fascinated by sharks, tsunamis, coral reefs, and super strange-looking fish. This book is a genuine contribution to our understanding of the world's vast wilderness. It introduces ocean water, geology, and geography, then moves on to a stunning catalogue of ocean life, from the smallest sponge to the largest whale.

Beautiful original photographs are combined with up-to-the-minute factual knowledge from marine biologists round the world. The human impact on the ocean is explained and challenged, actions are suggested, and young readers are introduced to a world of information and activity outside the book. Cool, modern graphics grab kids' attention. Layouts are structured for reluctant and eager readers alike-learn a little or learn a lot-it's your information journey. Includes thought-provoking math and science concepts: cause and effect and sequence and prediction. Vetted by literacy experts.
