Must-see Points

The number one spot to watch the whale sharks feed is near the panel of acrylic glass (Kuroshio Sea, 1F). The whale sharks are fed in the middle of the tank, while the manta rays are fed at the sides. The whale sharks stand straight up in the water when they feed. The manta rays are fed a few minutes after the whale shark feeding begins.
