A soothing story that answers the question of how marine mammals manage to breathe air while they sleep in the ocean. Youngsters meet ten mammals, including sea otters, dolphins, manatees, humpback whales and walruses, and learn about each animal's unique sleeping habits. While the brief portraits are based on up-to-date scientific research, the facts are woven into simple, poetic language and rich oil paintings capture the ocean's habitats and its appealing creatures. The educational supplement includes teaching trivia about marine mammals' adaptations to their watery environment, and a make-your-own marine mammal craft using various animal adaptations. For ages 2-8. All Sylvan Dell titles feature free education resources at www.SylvanDellPublishing.com, including the "For Creative Minds" sections and additional teaching activities.
