From this floor, you walk down the spiral slope, following the route and viewing a variety of seas and creatures inside their respective tanks: the Aleutians; a habitat of creatures like sea otters, harbor seals and California sea lions of Monterey Bay; the Gulf of Panama with long-spine porcupine fishes, capybaras and piranhas of the rainforest of Ecuador; king penguins of the Antarctic Continent; and Pacific white-sided dolphins at Tasman Bay. The Great Barrier Reef, the Pacific Ocean, the Seto Inland Sea and the Japan Deep are also recreated inside the aquarium's tanks.
