Sea Lions - In this intriguing segment, Jonathan goes diving with a group of playful sea lions in the Galapagos Islands. Impressed by the apparent inquisitiveness of the sea lions, Jonathan heads to the Mystic Aquarium in Connecticut where he learns how they train sea lions, and how smart they are. Jonathan finds out that the sea lions at Mystic know more than 100 commands, and he gets a lesson in sea lion training! Humpback Whales of the Silver Banks - Every year, Humpback whales in the North Atlantic make a long migration down to the Caribbean to have their calves in warm, calm water. Many of these whales go to one particular area called the Silver Banks near the Dominican Republic. Jonathan spends a week in the Silver Banks filming whales underwater, and you won't believe how close he gets to the whales, and the exceptional behaviors he observes!
