At the Baikal Seal Plaza, you can see, from a short distance of the observation deck, the freshwater Baikal seals, which are rare in the world, that came from Lake Baikal in Russia. Unique shows, which are also popular, are performed by the seals. You can see the difference in character of each seal. At the center of the Sea Pavilion, there is a large, open-air water tank that is 7 meters in height, and you can see various, lively saltwater fish swimming inside. During the water show in the large tank, the divers demonstrate how they feed the fish. You may observe rare, colorful fishes, such as the mysterious fishes from the Amazon River.
