An escalator takes you to the top, then you spiral down around the huge central Pacific Ocean tank. You see the same tank from a different depth on every level: rays skimming the surface near the top, then sharks on the sand and the slow pass of the whale shark as you go deeper. Penguins, otters and sea lions come in between, and the last dark room is full of drifting jellyfish. It is the classic rainy-day half day with kids.
