L'Oceanografic is an oceanarium situated in the east of the city of Valencia, Spain, where different marine habitats are represented. It was designed by the architect Félix Candela and the structural engineers Alberto Domingo and Carlos Lázaro. It is integrated inside the cultural complex known as the Ciutat de les Arts i de les Ciències (City of Arts and Sciences). It was opened on 14 February 2003.
The Oceanographic is the largest complex of its type in Europe, spanning 110,000 square metres (1,200,000 sq ft) and holding a capacity of 42,000,000 litres (11,000,000 US gal) of water, including a 26,000,000-litre (6,900,000 US gal) dolphinarium and a 7,000,000-litre (1,800,000 US gal) ocean tank with sharks, rays and other fish.
It is home to 45,000 animals from 500 different species—including sharks, penguins, dolphins, sea lions, walruses, beluga whales, birds, reptiles and invertebrate—all inhabiting nine two-tiered underwater towers representing the Earth's major ecosystems. The aquariums utilize sea water pumped from the La Malva-Rosa beach.
The park is divided into ten areas: the marine areas are arranged into Mediterranean habitats, the Arctic oceans, islands, the tropics, the temperate seas and the Red Sea. The park also includes a dolphinarium, an area of mangrove swamps and marshland, and a garden with more than 80 different species of plants.
