A 6,000-square-meter aquarium on the first floor of the Madrid Xanadú mall, with 10,000 animals across 20 marine habitats. The open-ocean hall is a domed walkway where blacktip and gray reef sharks, rays, and a loggerhead turtle swim around you. The polar zone has a column of snow kids can touch, and the Passport game handed out at the desk ends with a medal.
