From Flipper to Moby Dick to Sammy the Mad Seal, these marine mammal stories tell everything we've always wanted to know about whales, dolphins, sea lions, seals, and walruses. Is it true that they have a terrestrial origin? How do you dive so long and at great depths? How do mother sea lions and their young recognize each other? Is the killer whale a killer whale, or does it just play that dire role in Hollywood movies? Whether they are the specimens that take refuge in the ports, in Patagonia or the specimens of the high seas, these mammals have a special fascination for those of us who live with them.
Luis Cappozzo, one of the main specialists in marine biology, reveals the questions that surround the formidable warm-blooded animals that live in the oceans: their origins, their entertaining sex life, their dietary habits, plus the difficult survival between fishing boats and polluted waters.
