Sea World Indonesia, Public aquarium in Ancol, Indonesia
Sea World Indonesia is a public aquarium in Ancol specializing in marine life from Indonesian waters. The facility contains 28 display tanks with over 18,000 aquatic animals, including sharks, rays, turtles, and tropical fish from the Coral Triangle.
The aquarium opened in 1980 as part of the Ancol recreational complex to make Indonesian marine biodiversity accessible to the general public. Over the following decades, several expansions were made, including the addition of the underwater tunnel.
The name Antasena for the main tunnel comes from Javanese puppet theater, where it refers to a mythical water warrior. School groups from across Jakarta visit regularly to experience educational programs about coral reefs and overfishing.
The daily feeding show in the main tank begins at 14:30, when divers hand-feed the different species. A visit typically takes two to three hours, as the pathways through the facility are well signposted.
The Antasena Tunnel passes through five million liters of seawater and allows visitors to walk directly beneath swimming sharks and rays. The glass tube is long enough to spend several minutes inside and feel as if you are underwater yourself.
