Opened during the Lisbon World Exposition of 1998, the Oceanario is a top attraction. With over 1 million annual visitors, it offers an enchanting glimpse into the underwater world. Explore 8,000 sea creatures from 500 species, including penguins, otters, sharks, and corals. The main exhibit features a 5-million-liter saltwater aquarium, surrounded by habitats representing the North Atlantic, Antarctic, Temperate Pacific, and Tropical Indian Ocean. The journey unfolds on two levels, crossing temperate, tropical, and cold waters of different oceans. Notable installations include "Forests Underwater" and "ONE - The Sea as you've never felt it," both celebrating oceanic beauty and connection with nature. The Oceanario is not just a spectacle; it actively promotes ocean education, research, and conservation efforts, collaborating with various institutions. Expert biologists and engineers ensure high-quality exhibitions and consulting services for aquariums worldwide.
