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!
