Wilma the whale - What happens when a Beluga whale, normally found far north in the arctic, suddenly shows up in a Bay in Nova Scotia? What happens when she starts swimming with people and approaching boats full of tourists? This segment shows how one incredible friendly whale transformed a town, and captured the hearts of children and adults alike. The Prinz Eugen - Once the pride of the German Navy, this 700 foot long heavy cruiser was used by the U.S. as a test target for not one but two atom bombs at Bikini atoll. Today, at the bottom of the ocean, the radiation levels of the Prinz Eugen are low enough for safe exploration. Jonathan joins historian Mark Miller on a trip to explore this mysterious shipwreck. What they find about the condition of this wreck is surprising. The Mysterious Hammerhead - Of all the animals in the oceans, the hammerhead shark may be one of the strangest looking. The exact purpose of the wide, flat head is a mystery, but several theories abound. We travel to the shark-infested waters of the Galapagos in Ecuador to learn about the unusual habits of these sinister-looking sharks. Jonathan swims in schools of hundreds of hammerheads, and yet the sharks ignore him. What are the sharks up to?
