 Lisbon's Oceanarium is one of the world's largest aquariums. Designed by American architect Peter Chermeyeff, it rises from the river and is reached by a footbridge.
It is a deep-sea diving experience without any of the risks, with about 25,000 fish, seabirds, and mammals in an enormous central tank that is the size of four Olympic-sized swimming pools. Visitors can look into it from different levels for close-ups of the various creatures, including different species of sharks.
The Global Ocean tank, one of the world’s largest aquariums (4 million liters), is visible throughout a visit to the Oceanarium. The tank habitat is that of the high seas, and a good percentage of its inhabitants are large animals, known for being strong swimmers. Most are migratory species, and ranges can span several oceans. The best known are the sharks, rays and barracudas. Large shoals of fish can also be found on the high seas, although they are more common in coastal waters and on the continental shelf.
They are all separated from the main tank by invisible acrylic walls, giving the impression that all the creatures are swimming in the same space. There are also high-tech multilingual interactive displays explaining the development of ocean life.
