Oceanarium

The Lisbon Oceanarium is one of the world’s largest aquariums, which includes a deep-sea diving experience with approximately 25,000 fish, seabirds, and mammals in a tank the size of four Olympic-sized swimming pools.
The Oceanarium is the first to incorporate the world’s ocean habitats within a single environment; including an Antarctic tank containing penguins, and a Pacific tank with otters. The “tanks” are separated by acrylic walls, while giving the appearance of creatures swimming together in the same space.
