Underwater World Langkawi is one of the largest aquaria in Malaysia. Since the start of its operation on 26 August 1995, it has become one of the must visit tourist destinations in Langkawi and has attracted a large number of foreign as well as local tourists. The concept and theme of Underwater World Langkawi are geared towards Knowledge, Education and Entertainment. It is built to raise awareness on the importance of conserving our precious aquatic life forms, thus creating understanding of the deep and inseparable bond between man and nature. Unique to Underwater World Langkawi is the gigantic 15-meter long walk-through tunnel consisting of 500,000 litre seawater which houses many big fishes and sea creatures. The 34,701 square foot oceanarium is located adjacent to a shopping centre and the Neptune Café. Visitors are thus provided with a one-stop shopping, eating and entertainment package, all of which are available within one area. A new building (with 60,000 sq. ft built-up area) which displays Tropical Rainforest, Temperate and Sub-Antarctic Ecosystems, and info theatre with a 200-seating capacity will be opened to the public in early 2005. The Sub-Antarctic Ecosystem Display includes a spectacular “penguinarium” with an underwater tunnel for visitors to view swimming penguins.
