The Underwater World aquarium was opened in Sentosa in Singapore in 1991. The aquarium offers a view of more than a total of 2500 marine animals and is located close to the Siloso point. The Dolphin Lagoon at the Underwater World provides a great show where visitors can see the interaction between dolphins and their trainers. In the photo, the show is ongoing, and part of the show is where the dolphins jump over the trainer who is in the water and then land back in the water. The photo shows the trainer part.
