This soothing bedtime story explains how ten different marine mammals-animals that live in water but breathe air-sleep in the ocean. Based on up-to-date scientific research, the brief portraits are explained in simple, poetic language. Water Beds invites children to drift into sleep on gentle waves of imagination. The "For Creative Minds" educational section includes fun facts about marine mammal adaptations, and a "Design Your Own Marine Mammal" craft.
