Lisboa, Portugal
The main exhibit is a 1,000 m2 (11,000 sq ft) tank. It is 7 m (23 ft) deep, which allows pelagic swimmers to swim above the bottom dwellers, and provides the illusion of the open ocean. About 100 species from around the world are kept in this tank, including sharks, rays, barracudas, groupers, and moray eels.
