Starting with the seashore and journeying through the ocean's zones, readers 9 to 12 will discover mangrove forests, coral reefs, and the deepest ocean depths—plus the wondrous creatures that call these places home. Color photos appear throughout this substantial guide, while the detailed text is complemented by a foreword from explorer Brian Skerry, an interview with marine conservationist Jess Cramp, and a poem by former children's poet laureate J. Patrick Lewis.
