The Marine Life Park is a part of Resorts World Sentosa, Sentosa, situated in southern Singapore. The 8-hectare (20-acre) park houses two attractions, the S.E.A. Aquarium and the Adventure Cove Waterpark. The S.E.A. Aquarium (South East Asia Aquarium) was the world's largest aquarium by total water volume until overtaken by Chimelong Ocean Kingdom in Hengqin, China.
It contains a total of 45,000,000 litres (9,900,000 imp gal; 12,000,000 US gal) of water for more than 100,000 marine animals of over 800 species. The aquarium comprises 10 zones with 49 habitats. The centerpiece of the aquarium is the Open Ocean tank with more than 18,000,000 l (4,000,000 imp gal; 4,800,000 US gal) and 50,000 animals.
Until 2014 when eclipsed by China's Chimelong Ocean Kingdom, it had the world's largest viewing panel, 36-metre (118 ft) wide and 8.3-metre (27 ft) tall, which is intended to give visitors the feeling of being on the ocean floor. The aquarium houses the world's largest collection of manta rays, including one of only a few giant oceanic manta rays in captivity.
It also showcases 24 Indo-Pacific bottlenose dolphins, scalloped hammerhead sharks, the Japanese spider crab, and relatively uncommonly-exhibited species such as the guitarfish and the chambered nautilus.
