Overview: A Japanese aquarium that was once in dire straits has become the world's center for jellyfish research, thanks to its current director, Okuizumi Kazuya. He proposed setting up a jellyfish exhibit many years ago. At the time, he was a young man with little self-esteem. But the success of the exhibit gave him a new perspective. Today, he's become a leading expert in jellyfish, and his fish tank designs have been adopted by aquariums world over. He shares his passion for jellyfish with our host, Robert Campbell.
