Youngsters meet ten marine mammals, including sea otters, bottlenose dolphins, manatees, harbor seals, humpback whales and walruses, and learn about each animal s unique sleeping habits. Although the brief portraits are based on up-to-date scientific research, author Gail Langer Karwoski weaves the facts into simple, poetic language. Connie McLennan s rich oil paintings capture the ocean s habitats and its appealing creatures. The story invites children to drift into peaceful sleep on the gentle waves of imagination. The educational supplement includes teaching trivia about marine mammals, their sleeping habits, and how they have adapted to their watery environment. It also includes a make-your-own marine mammal craft using various animal adaptations.
