Learn how deep a sperm whale can dive, how whales use bubbles to catch fish, why sea lions bark like dogs, what baleen is used for, and why killer whales come up on the beach. Discover how humpback whales communicate, why whales leap, the world's biggest baby, why the future of whales, seals, and dolphins is threatened, why whales migrate thousands of miles, and much, much more!
