What is special about the Seattle Aquarium is that it is not a rebuilt aquarium itself, but a glass is set underground to show the real scenes on the sea floor. The aquarium focuses on four points: First, there is a huge glass in the door, don't miss the divers feeding fish show. Second, the experience and explanation area, where you can touch any undersea creature, including starfish, except for fish. Each booth has a staff explanation, if you don't understand, you can consult them at any time.
