Onboard a vessel that would make Jacques Cousteau green with envy, the Cat and Co. take to the high seas in search of whales, dolphins, and porpoises—those aquatic mammals known as cetaceans. While learning how cetaceans stay warm without hair, have teeth or baleen, swim in troops, spyhop, spin, breach, and see via ecolocation, kids are introduced to almost 20 different species—including sperm, right, humpback, and blue whales; Gulf, spectacled, and finless porpoise; and boto, common, hourglass, and bottlenose dolphins. A shipshape selection for summer reading! "The Cat in the Hat's Learning Library shows young readers that books can be entertaining and educational at the same time. This is a wonderful series!" —Barbara Kiefer, Ph.D., Charlotte S. Huck Professor of Children's Literature, Ohio State University
