Sydney Aquarium

Sydney Aquarium is a public aquarium located in the city of Sydney, New South Wales, Australia. It is located on the eastern (city) side of Darling Harbour to the north of the Pyrmont Bridge. It is a full institutional member of the Zoo and Aquarium Association (ZAA) and the World Association of Zoos and Aquariums (WAZA).
The aquarium contains a large variety of Australian aquatic life, displaying more than 650 species comprising more than 6,000 individual fish and other sea and water creatures from most of Australia's water habitats.
Its key exhibits in the aquarium are a series of underwater, see-through, acrylic glass tunnels where sharks swim above visitors, and recreation of a Great Barrier Reef coral environment.
 

History

The aquarium was designed by Australian architects to resemble a large wave, to complement the underwater theme of an aquarium and the maritime theme of Darling Harbour, and took nearly two years to build. The Great Barrier Reef complex which opened in October 1998 continues this same theme.
The Sydney Aquarium was opened in 1988, during Australia's bicentenary celebrations, and is one of the largest aquariums in the world. It is regarded as one of Sydney's premier tourist attractions with over 55% of its visitors each year coming from overseas. A crocodile exhibit was added in 2008.
In December 1991, the first Seal Sanctuary was opened. Since then, Sydney Aquarium has upgraded the facilities and a new oceanarium to house seals opened in September 2003. The Seal Sanctuary features Australian Sea Lions, Australian Fur Seals, Subantarctic Fur Seals, and New Zealand Fur Seals. In this floating oceanarium, the seals can be seen below the water's surface from underwater viewing tunnels, and from above on an open-air deck. The Seal Sanctuary is incorporated into the Southern Oceans exhibit, which also features Little Penguins, the Open Ocean Oceanarium, and Sydney Harbour displays.
In October 1998, the Great Barrier Reef complex opened comprising a tropical touch pool, a live coral cave, coral atoll, two circular gateway displays and a massive Great Barrier Reef oceanarium. Over 6,000 animals are housed in the oceanarium which contains 2.6 million litres (572,000 imp gal, 687,000 U.S. gal) of water pumped from Darling Harbour, filtered and heated before it flows into the Oceanarium and adjoining display tanks. The water is kept at a constant temperature of 25 °C (77 °F). The Oceanarium is 33 metres (108 ft) long and 13 metres (43 ft) wide, with a total area of about 370 square metres (4,000 sq ft) and a water depth of 3.5 metres (11 ft). The final exhibit is a reef theatre where activity in a coral canyon can be observed through a window 7 by 4 metres (23 by 13 ft) and 26 centimetres (10 in) in thickness.
In 2006, Wild Life Sydney opened next to Sydney Aquarium, which is also owned by Merlin Entertainment.
On 20 December 2007, the glass-bottomed boat, or Shark Explorer, began operating, giving guests a tour of the Great Barrier Reef tank.
In 2008 the seal sanctuary was closed and the seals were sent to Sea World, Gold Coast, Australia. The seal sanctuary was then renovated and reopened as Mermaid Lagoon in December 2008. Mermaid Lagoon is the new permanent home of Pig and Wuru, dugongs which were previously kept at Sea World, Gold Coast. Mermaid Lagoon has above-water viewing areas as well as underwater viewing tunnels. Other animals kept in the oceanarium include a shark ray, shovelnose rays, zebra sharks, eagle rays and dozens of different species of fish.
A Lego exhibit, Lego on the Loose, opened on 22 December 2010.
In March 2012, Sydney Aquarium's owners, Merlin Entertainments, announced that they would be spending $10 million on the refurbishment of the facilities. As part of the process, the aquarium will be rebranded as a Sea Life Centre and will reopen in September 2012.

The Sydney Aquarium has distinctly Australian themes and exhibits, which take visitors through the continent's waterways and marine ecosystems. Exhibits cover the rivers of Australia, exploring the Southern and Northern River habitats, as well as the oceans of Australia, through the Southern and Northern Ocean habitats. The complex and fragile nature of Australia's very different and unique aquatic environments is emphasised.
Some of the displays are housed in the main exhibit hall and others are housed in floating oceanariums. The Seal Sanctuary and Open Ocean exhibits comprise two massive oceanariums, amongst the largest in the world, and have underwater tunnels allowing visitors to examine marine life at close quarters. In the Open Ocean Oceanarium, Sydney Aquarium houses the largest collection of sharks in captivity. Some of the sharks weigh up to 300 kilograms (660 lb) and are over 3 metres (9.8 ft) in length.
