Sorry 'bout the typo in the title! Atlanterhavsparken, Ålesund Akvarium is perhaps most famous for their excellent 4 million liter (1 million gallon) main tank with native marine fish such as cod, wolffish and halibut, which measures 35 x 17 x 7 m on the longest/broadest/deepest sections. They also have various smaller tanks showing other local habitats, a handful of smaller tropical tanks and a Humboldt penguin exhibit. A few days ago, they've opened what supposedly is the largest seal exhibit in Europe. With a remarkable 6000 m2 (65000 square ft) and 15 million liters (4 million gallon) of water I wouldn't be surprised if "selbukta" (seal bay) actually is the largest in the world. At present, they have two male and four female harbor seals. Their own page about the seal exhibit in Norwegian: http://www.atlanterhavsparken.no/index.php?page_id=805&parent=21 Photo gallery from the opening: I bilder: Åpning av selbukta -smp.no Another gallery: Selar på plass i Atlanterhavsparken - NRK ? Møre og Romsdal I've not seen it in person, but it appears to follow the general concept of fencing in a local habitat, as also used by some other Scandinavia zoos such as Denmark's Skandinavisk Dyrepark and Sweden's Orsa Björnpark.
